Upgrade SlackerMail

• Upgrade from v0.55.0 to v0.55.1

  Update /etc/SlackerMail-release with new release number

  echo "0.55.1" > /etc/SlackerMail-release
  

  Disable logging "New not syn:" messages from iptables firewall

  Edit /etc/rc.d/rc.firewall
  Comment the following in the rc.firewall file:
  
  #$IPT -A bad_tcp_packets -p tcp ! --syn -m conntrack --ctstate NEW -j LOG \
  #    --log-prefix "New not syn: "
  

  Disable logging "IPv4: martian source" messages from iptables firewall

  Edit /etc/rc.d/rc.firewall
  Comment the following in the rc.firewall file:
  
  # This option logs packets from impossible addresses.
  #if [ "$SYSCTL" = "" ]
  #then
  #    echo "1" > /proc/sys/net/ipv4/conf/all/log_martians
  #else
  #    $SYSCTL net.ipv4.conf.all.log_martians="1"
  #fi
  

  Change /etc/hosts localhost setting

  Edit /etc/hosts
  Change from:
  127.0.0.1 localhost.localdomain localhost - This can cause problems, very rarely, but it can cause problems.
  
  To:
  127.0.0.1 localhost
  

  Spamassassin sa-compile

  This is suppose to help Spamassassin run more efficiently. Run the following on the command line:

  LogLevel INFO
  

  That should do it for upgrading to SlackerMail v0.55.1

• Upgrade from v0.54.0 to v0.55.0

  rm rust-opt-1.91.1-x86_64-1_SBo.tgz
  

  Apache - Add two location settings so Netdata can monitor apache and phpfpm.

  In /etc/httpd/extra/httpd-ssl.conf add two location settings.
  
  <location /netdata/>
     AuthType Basic
     AuthName "Restricted Content"
     AuthUserFile /etc/httpd/netdata.users
     Require valid-user
     Order deny,allow
     Allow from all
  </location>
  
  Put the following just below the one above.
  
  <Location "/server-status">
      SetHandler server-status
      Order deny,allow
      Allow from 127.0.0.1
  </Location>
  
  <Location "/status">
      SetHandler "proxy:fcgi://127.0.0.1:9000/status"
      Order deny,allow
      Allow from 127.0.0.1
  </Location>
  

  Nginx - Moved settings to always use HSTS "HTTP Strict Transport Security".

  # HTTPS
  server {
      listen 443 ssl;
      http2 on;
      server_name _;
      root /var/www/html;
      index index.php index.html;
      location ~ ^/.well-known/ {
          allow all;
          access_log off;
          log_not_found off;
          autoindex off;
          #root /var/www/html;
      }
      # Note! - Add the below add_header setting in /etc/nginx/conf.d/mailserver.conf just below the above server setting.
      add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always; 
      
      # Remove the two "add_header Strict-Transport-Security "max-age=31536000";" settings in:
      location ~ ^/mail/(.*\.php)$ {
      and
      location ~ ^/postfixadmin/(.*\.php)$ {
  

  Postfix - made two changes in the /etc/postfix/main.cf file:

  Changed "mydomain = $myhostname" to "mydomain = example.org"
  Added "smtpd_discard_ehlo_keywords = chunking" just below "show_user_unknown_table_name = no"
  

  Mysql - Added one setting in /etc/my.cnf.d/server.cnf

  Under [mysqld]
  Added "performance_schema = 0" 
  Uses less memory without hurting perfomance.
  

  Netdata:

  a. Upgraded to v2.8.1:

  wget https://github.com/netdata/netdata/releases/download/v2.8.1/netdata-v2.8.1.gz.run
  chmod 0755 netdata-v2.8.1.gz.run
  ./netdata-v2.8.1.gz.run --accept
  rm netdata-v2.8.1.gz.run
  

  b. Changed the phpfpm monitor from socket to url:

  Change /opt/netdata/etc/netdata/go.d/phpfpm.conf to:
  
  jobs:
    - name: local
      url: https://127.0.0.1/status?full&json
      tls_skip_verify: yes
  

  c. Changed the netdata mysql database, so it will work properly with the newer netdata:

  mysql -u root -p
  DROP USER 'netdata'@'localhost';
  GRANT PROCESS ON *.* TO netdata@localhost IDENTIFIED BY 'mysql-netdata-password';
  FLUSH PRIVILEGES;
  QUIT;
  

  Disable /etc/rc.d/rc.ntpd - I do ntpdate time updates daily and at bootup, and with ntpd running it will not work and time will be off.

  chmod 0644 /etc/rc.d/rc.ntpd
  

  That should do it for upgrading to SlackerMail v0.55.0

• Upgrade from v0.53.5 to v0.54.0

  Update /etc/SlackerMail-release with new release number

  echo "0.54.0" > /etc/SlackerMail-release
  

  Made changes to /etc/postfix/main.cf and /etc/postfix/master.cf

  Remove the line "mailbox_size_limit = 0" with the sed command below:

  sed -i '/mailbox_size_limit = 0/d' /etc/postfix/main.cf
  

  Add the following 3 lines to /etc/postfix/main.cf:

  #Set max mailbox and message size
  mailbox_size_limit = 0
  message_size_limit = 15728640

  With the sed command below:

  sed -i '63i#Set max mailbox and message size\
  mailbox_size_limit = 0\
  message_size_limit = 15728640\
  ' /etc/postfix/main.cf
  

  Edit /etc/postfix/master.cf

  In the line in /etc/postfix/master.cf "smtp-amavis unix -  -   n   -   16  smtp", the 16 needs to
  be changed to 8 to match "$max_servers = 8;" in /etc/amavisd.conf. You can also change amavisd.conf
  "$max_servers = 8;" to match master.cf with 16. Just make sure the two match.
  

  Downgrade php-imagick-3.8.0 to php-imagick-3.7.0. php-imagick-3.7.0 is meant for php7, which is what we have.

  wget https://the-slacker.com/download/php-imagick-3.7.0-x86_64-2_SBo.tgz

  Make a minor adjustment to the smmlm mailing list manager.

  Edit /var/spool/smmlm/smmlm:

  Change:
  INSERT INTO lists (email) VALUES("$MLADD1");
  To:
  INSERT INTO lists (email) VALUES('$MLADD1');

  chmod 0755 netdata-v2.7.2.gz.run
  ./netdata-v2.7.2.gz.run --accept
  rm netdata-v2.7.2.gz.run
  

  That should do it for upgrading to SlackerMail v0.53.5

• Upgrade from v0.53.3 to v0.53.4

  Update /etc/SlackerMail-release with new release number.

  echo "0.53.4" > /etc/SlackerMail-release
  

  Upgrade Postfixadmin to v3.3.16

  Download and install postfixadmin-3.3.16.

  cd /var/www
  wget https://github.com/postfixadmin/postfixadmin/archive/refs/tags/postfixadmin-3.3.16.tar.gz
  tar -xf postfixadmin-3.3.16.tar.gz
  rm postfixadmin # This just removes the link to postfixadmin-postfixadmin-3.3.15. Keep the old postfixadmin around for awhile just incase something goes wrong.
  ln -s postfixadmin-postfixadmin-3.3.16 postfixadmin
  cd postfixadmin
  mkdir templates_c
  chmod 750 templates_c
  If Apache is your web server then:
  chown apache:root templates_c
  If Nginx is your web server then:
  chown nginx:root templates_c
  Then copy your config.local.php from 3.3.15 to 3.3.16:
  cp /var/www/postfixadmin-postfixadmin-3.3.15/config.local.php /var/www/postfixadmin-postfixadmin-3.3.16/config.local.php
  Then edit /var/www/postfixadmin-postfixadmin-3.3.16/config.local.php at the end of the file change $CONF['version'] = '3.3.15'; to $CONF['version'] = '3.3.16';
  Since config.local.php has passwords in it you'll need to change ownershp and permissions on that file:
  If Apache is your web server:
  chown root:apache config.local.php
  chmod 0640 config.local.php
  If Nginx is your web server:
  chown root:nginx config.local.php
  chmod 0640 config.local.php
  Okay, now try to log into your postfixadmin control panel, and your roundcube webmail client, to see if they are working properly.

  rm /etc/cron.daily/0logwatch
  touch /etc/cron.daily/0logwatch
  chmod 0755 /etc/cron.daily/0logwatch
  

  Then run the following echo command to create the logwatch daily cron job:

  echo '#!/bin/sh
  #Set logwatch location
  LOGWATCH_SCRIPT="/usr/sbin/logwatch"
  #Add options to this line. Most options should be defined in /etc/logwatch/conf/logwatch.conf,
  #but some are only for the nightly cronrun such as --output mail and should be set here.
  #Other options to consider might be "--format html" or "--encode base64", man logwatch for more details.
  OPTIONS="--output mail"
  #Call logwatch
  $LOGWATCH_SCRIPT $OPTIONS
  exit 0' >> /etc/cron.daily/0logwatch

• Upgrade from v0.50.1 to v0.51.0

  Change from rust16 to rust-opt required by clamav-v1.4.2

  First we need to stop clamav:

  /etc/rc.d/rc.clamav stop
  

  Then remove the rust16 package:

  removepkg rust16-1.79.0-x86_64-1_SBo
  

  Then download and install the rust-opt package:

  cd /root/tmp
  wget https://the-slacker.com/download/rust-opt-1.84.0-x86_64-1_SBo.tgz
  installpkg rust-opt-1.84.0-x86_64-1_SBo.tgz
  rm rust-opt-1.84.0-x86_64-1_SBo.tgz
  

  Upgrade clamav to v1.4.2

  Download and upgrade to clamav-v1.4.2

  cd /root/tmp
  wget https://the-slacker.com/download/clamav-1.4.2-x86_64-1_SBo.tgz
  upgradepkg clamav-1.4.2-x86_64-1_SBo.tgz
  rm clamav-1.4.2-x86_64-1_SBo.tgz
  

  Now start clamav:

  /etc/rc.d/rc.clamav start
  

  Clamav should be running properly now.

  Upgrade Netdata to v2.2.1

  Download and upgrade Netdata:

  cd /root/tmp

  That should do it for upgrading to SlackerMail v0.51.0.

• Upgrade from v0.50.0 to v0.50.1

  Configure roundcubemail password plugin so it will work as expected:

  To configure the roundcubemail password plugin, so you can change passwords, go Here.

  Change postfixadmin encryption method from md5crypt to dovecot:SSHA512:

  If you have Apache then:

  usermod -aG vmail apache
  

  If you have Nginx then:

  usermod -aG vmail nginx
  

  Then you'll need to edit /var/www/postfixadmin/config.local.php:

  Change:
  $CONF['encrypt'] = 'md5crypt';
  to:
  $CONF['encrypt'] = 'dovecot:SSHA512';
  

  Then you'll need to update the postfixadmin admin account to use the new encryption:

  /var/www/postfixadmin/scripts/postfixadmin-cli admin update admin@example.org --superadmin 1 --active 1 --password password  --password2 password
  

  You should now be able to login to your postfixadmin control panel at https://example.org/postfixadmin as admin@example.org with the "password" you entered
  twice in the above postfixadmin-cli update command, and postfixadmin should now use the dovecot:SSHA512 encryption when adding new mailboxes.

  That should do it for upgrading to SlackerMail v0.50.1.

• Upgrade from v0.49.0 to v0.50.0

  Upgrade Postfixadmin to v3.3.15:

  First backup your vmail database. You shouldn't need it, but best to be safe.

  mysqldump -u root -p vmail > /tmp/vmail-backup.sql
  

  Then download and install postfixadmin-3.3.15.

  cd /var/www
  wget https://github.com/postfixadmin/postfixadmin/archive/refs/tags/postfixadmin-3.3.15.tar.gz
  tar -xf postfixadmin-3.3.15.tar.gz
  rm postfixadmin # This just removes the link to postfixadmin-postfixadmin-3.3.14. Keep the old postfixadmin around for awhile just incase something goes wrong.
  ln -s postfixadmin-postfixadmin-3.3.15 postfixadmin
  cd postfixadmin
  mkdir templates_c
  chmod 750 templates_c
  If Apache is your web server then:
  chown apache:root templates_c
  If Nginx is your web server then:
  chown nginx:root templates_c
  Then copy your config.local.php from 3.3.14 to 3.3.15:
  cp /var/www/postfixadmin-postfixadmin-3.3.14/config.local.php /var/www/postfixadmin-postfixadmin-3.3.15/config.local.php
  Then edit /var/www/postfixadmin-postfixadmin-3.3.15/config.local.php at the end of the file change $CONF['version'] = '3.3.14'; to $CONF['version'] = '3.3.15';
  Since config.local.php has passwords in it you'll need to change ownershp and permissions on that file:
  If Apache is your web server:
  chown root:apache config.local.php
  chmod 0640 config.local.php
  If Nginx is your web server:
  chown root:nginx config.local.php
  chmod 0640 config.local.php
  Okay, now try to log into your postfixadmin control panel, and your roundcube webmail client, to see if they are working properly.

  chmod 750 templates_c
  If Apache is your web server then:
  chown apache:root templates_c
  If Nginx is your web server then:

  cp /var/www/postfixadmin-postfixadmin-3.3.13/config.local.php /var/www/postfixadmin-postfixadmin-3.3.14/config.local.php
  Then edit /var/www/postfixadmin-postfixadmin-3.3.14/config.local.php at the end of the file change $CONF['version'] = '3.3.13'; to $CONF['version'] = '3.3.14';
  Since config.local.php has passwords in it you'll need to change ownershp and permissions on that file:
  If Apache is your web server:

  Nothing needed to upgrade here. Just made a change in the SlackerMail install script.

• Upgrade from v0.40.0 to v0.41.0

  Upgrade Mariadb

  We will be installing the latest Mariadb security update, mariadb-10.5.25. Make sure mariadb* is removed from the /etc/slackpkg/blacklist file.
  mariadb-10.5.25 will not work properly, without some tinkering, if installed on a fresh Slackware64-15.0 system without there already being a
  mysql database present, but since we already had the mysql database installed with the initial SlackerMail setup, we can install mariadb-10.5.25
  with no problems.

  After you've removed mariadb* from the blacklist file, then download, install, and restart the mariadb-10.5.25 package with:

  wget https://the-slacker.com/download/mariadb-10.5.25-x86_64-1_slack15.0.txz
  upgradepkg mariadb-10.5.25-x86_64-1_slack15.0.txz
  /etc/rc.d/rc.mysqld restart > /dev/null 2>&1
  rm mariadb-10.5.25-x86_64-1_slack15.0.txz
  

  Now you should have mariadb-10.5.25 installed, and it should be working as expected.

  Upgrade Webmin

  Upgrade Webmin from the Webmin control panel. It will notify you of any upgrades.

  Upgrade Netdata

  wget https://github.com/netdata/netdata/releases/download/v1.46.3/netdata-v1.46.3.gz.run
  chmod 0755 netdata-v1.46.3.gz.run
  ./netdata-v1.46.3.gz.run --accept
  rm netdata-v1.46.3.gz.run
  

  That should do it for upgrading to SlackerMail v0.41.0.

• Upgrade from v0.39.0 to v0.40.0

  Make sure mariadb is blacklisted in /etc/slackpkg/blacklist before you do the system upgrade. The latest Slackware mariadb-10.5.25 is broke. Just
  put the line mariadb* in the blacklist file.

  Now you can do a full system upgrade safely. Just run the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Remove the /etc/fail2ban/jail.d/apache-4xx.local jail. It can cause problems with email.

  rm /etc/fail2ban/jail.d/apache-4xx.local
  

  Upgrade to Netdata v1.46.1.

  wget https://github.com/netdata/netdata/releases/download/v1.46.1/netdata-v1.46.1.gz.run
  chmod 0755 netdata-v1.46.1.gz.run

  upgradepkg rust16-1.79.0-x86_64-1_SBo.tgz
  rm rust16-1.79.0-x86_64-1_SBo.tgz
  

  That should do it for upgrading to SlackerMail v0.40.0.

• Upgrade from v0.38.0 to v0.39.0

  Make sure mariadb is blacklisted in /etc/slackpkg/blacklist before you do the system upgrade. The latest Slackware mariadb-10.5.25 is broke. Just
  put the line mariadb* in the blacklist file.

  Now you can do a full system upgrade safely. Just run the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Remove the python2-PyYAML-3.13-x86_64-1_SBo.tgz package. It's not needed as the "pip3 install mysql-connector-python" installs the python3 version needed by Netdata:

  removepkg python2-PyYAML-3.13-x86_64-1_SBo.tgz
  

  Enable the Fail2ban apache-4xx jail:

  Just edit /etc/fail2ban/jail.d/apache-4xx.local file and set "enabled = true", then restart Fail2ban:
  /etc/rc.d/rc.fail2ban restart
  

  That should do it for upgrading to SlackerMail v0.39.0.

• Upgrade from v0.37.0 to v0.38.0

  Make sure mariadb is blacklisted in /etc/slackpkg/blacklist before you do the system upgrade. The latest Slackware mariadb-10.5.25 is broke. Just
  put the line mariadb* in the blacklist file.

  Now you can do a full system upgrade safely. Just run the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Upgrade Nginx to the latest stable version:

  Important! Make sure to backup your /var/www/html/index.html file before you upgrade Nginx, because it will overwrite that file.

  chmod 0755 netdata-v1.45.6.gz.run
  ./netdata-v1.45.6.gz.run --accept
  rm netdata-v1.45.6.gz.run
  

  That should do it for upgrading to SlackerMail v0.38.0.

• Upgrade from v0.36.1 to v0.37.0

  We'll have to blacklist mariadb in slackpkg before you can do an upgrade. The latest Slackware mariadb security update mariadb-10.5.25 is broken.
  Once this is sorted we can un-blacklist mariadb. Just run the echo command below to blacklist mariadb:

  echo "mariadb*" >> /etc/slackpkg/blacklist
  

  Now you can do a full system upgrade safely. Just run the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Next we upgrade Roundcube to v1.6.7:

  1. Edit /etc/php.ini at about line 312 where is starts with "disable_functions =", and remove "system" from the list, then run "/etc/rc.d/rc.php-fpm restart" from the command line.
  2. wget https://github.com/roundcube/roundcubemail/releases/download/1.6.7/roundcubemail-1.6.7-complete.tar.gz
  3. tar -xf roundcubemail-1.6.7-complete.tar.gz
  4. cd roundcubemail-1.6.7
  5. bin/installto.sh /var/www/roundcubemail
  6. rm roundcubemail-1.6.7-complete.tar.gz
  7. Edit /etc/php.ini again and add system back to the disable_functions = list, and run /etc/rc.d/rc.php-fpm to restart php-fpm.
  

  Upgrade Netdata to v1.45.5:

  wget https://github.com/netdata/netdata/releases/download/v1.45.5/netdata-v1.45.5.gz.run
  chmod 0755 netdata-v1.45.5.gz.run
  ./netdata-v1.45.5.gz.run --accept
  rm netdata-v1.45.5.gz.run
  

  Remove package gnome-keyring. I don't like using keys for sshd myself, so this is optional.

  removepkg gnome-keyring
  

  Reformat the "disable_funtions =" line in /etc/php.ini so it conforms to standards properly. Just copy, paste, and run the entire sed command below:

  sed -i "/disable_functions =/c\disable_functions = system,posix_uname,eval,pcntl_wexitstatus,posix_getpwuid,xmlrpc_entity_decode,\
  pcntl_wifstopped,pcntl_wifexited,pcntl_wifsignaled,phpAds_XmlRpc,pcntl_strerror,ftp_exec,pcntl_wtermsig,mysql_pconnect,proc_nice,\
  pcntl_sigtimedwait,posix_kill,pcntl_sigprocmask,fput,phpinfo,phpAds_remoteInfo,ftp_login,inject_code,posix_mkfifo,highlight_file,\
  escapeshellcmd,show_source,pcntl_wifcontinued,fp,pcntl_alarm,pcntl_wait,ini_alter,posix_setpgid,parse_ini_file,ftp_raw,pcntl_waitpid,\
  pcntl_getpriority,ftp_connect,pcntl_signal_dispatch,pcntl_wstopsig,ini_restore,ftp_put,passthru,proc_terminate,posix_setsid,pcntl_signal,\
  pcntl_setpriority,phpAds_xmlrpcEncode,pcntl_exec,ftp_nb_fput,ftp_get,phpAds_xmlrpcDecode,pcntl_sigwaitinfo,shell_exec,pcntl_get_last_error,\
  ftp_rawlist,pcntl_fork,posix_setuid" /etc/php.ini
  

  That should do it for upgrading to SlackerMail v0.37.0.

• Upgrade from v0.36.0 to v0.36.1

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Delete line from /etc/nginx/conf.d/mailserver.conf:

  Delete this line: "location ~* \.(jpg|png|gif)$ { access_log off; log_not_found off; }"
  
  Then restart nginx with the following command: /etc/rc.d/rc.nginx restart
  

  Upgraded Rust16 to the latest stable version v1.78.0:

  wget https://the-slacker.com/download/rust16-1.78.0-x86_64-1_SBo.tgz
  upgradepkg rust16-1.78.0-x86_64-1_SBo.tgz
  rm rust16-1.78.0-x86_64-1_SBo.tgz
  

  Add the nginx-bad-request jail for fail2ban:
  Just copy, paste, and run the echo command below.

  echo "[nginx-bad-request]
  enabled = true
  filter  = nginx-bad-request
  logpath = /var/log/nginx/access.log" > /etc/fail2ban/jail.d/nginx-bad-request.local
  

  Change default fail2ban bantime to 604800 (1 week):
  

  Run sed command below:
  sed -i "/bantime  = 86400/c\bantime  = 604800" /etc/fail2ban/jail.local
  
  Restart fail2ban: /etc/rc.d/rc.fail2ban restart
  

  That should do it for upgrading to SlackerMail v0.36.1.

• Upgrade from v0.35.0 to v0.36.0

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Upgrade Rust16 to v1.77.2:

  wget https://the-slacker.com/download/rust16-1.77.2-x86_64-1_SBo.tgz
  upgradepkg rust16-1.77.2-x86_64-1_SBo.tgz
  rm rust16-1.77.2-x86_64-1_SBo.tgz
  

  Upgrade Netdata to v1.45.4:

  wget https://github.com/netdata/netdata/releases/download/v1.45.4/netdata-v1.45.4.gz.run
  chmod 0755 netdata-v1.45.4.gz.run
  ./netdata-v1.45.4.gz.run --accept
  rm netdata-v1.45.4.gz.run
  

  If Nginx is your web server, then add the nginx-botsearch fail2ban jail with the following echo command:

  echo "[nginx-botsearch]
  enabled = true
  filter  = nginx-botsearch
  logpath = /var/log/nginx/access.log" > /etc/fail2ban/jail.d/nginx-botsearch.local
  

  Change Dovecot so that all log messages go to /var/log/dovecot/dovecot.log.

  Edit /etc/dovecot/conf.d/10-logging.conf and make sure you have the following 2 lines pertaining to logs:

  log_path       = /var/log/dovecot/dovecot.log
  info_log_path  = /var/log/dovecot/dovecot.log
  

  Edit /etc/dovecot/conf.d/15-lda.conf and delete anything pertaining to a log path.
  Edit /etc/dovecot/conf.d/20-lmtp.conf and delete anything pertaining to a log path.
  Edit /etc/dovecot/conf.d/90-sieve.conf and delete anything pertaining to a log path.

  Make sure owner and permissions are correct for /var/log/dovecot and /var/log/dovecot/dovecot.log:

  chown vmail:vmail /var/log/dovecot
  chown vmail:vmail /var/log/dovecot/dovecot.log
  chmod 0755 /var/log/dovecot
  chmod 0660 /var/log/dovecot/dovecot.log
  

  Now all log messages from Dovecot should go to /var/log/dovecot/dovecot.log

  Lastly make sure the Dovecot logs are rotated properly with the echo command below:

  echo "/var/log/dovecot/dovecot.log {
  rotate 5
  daily
  dateext
  compress
  compresscmd /bin/bzip2
  uncompresscmd /bin/bunzip2
  compressext .bz2
  notifempty
  missingok
  create 0660 vmail vmail
  sharedscripts
  
  postrotate
    doveadm log reopen
  endscript
  }" > /etc/logrotate.d/dovecot
  

  That should do it for upgrading to SlackerMail v0.36.0.

• Upgrade from v0.34.2 to v0.35.0

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  If Nginx is your webserver then upgrade to the latest stable version v1.26.0:
  Make sure to back up your /var/www/html/index.html file because the Nginx upgrade will overwrite it.

  wget https://the-slacker.com/download/nginx-1.26.0-x86_64-1_SBo.tgz
  upgradepkg nginx-1.26.0-x86_64-1_SBo.tgz
  rm nginx-1.26.0-x86_64-1_SBo.tgz
  

  If Nginx is your webserver then edit /etc/nginx/conf.d/mailserver.conf and make the following change.

  Change:
  
  # HTTPS
  server {
      listen 443 ssl http2;
  
  To:
  
  # HTTPS
  server {
      listen 443 ssl;
      http2 on;
  

  If Nginx is your webserver then edit /etc/nginx/conf.d/mailserver.conf and add 1 line as below.

  location ~ /\. { deny all; }
  location ~* \.(jpg|png|gif)$ { access_log off; log_not_found off; } # This is the line you will need to add. It prevents some unnecessary logging in the Nginx logs.
  location = /favicon.ico { access_log off; log_not_found off; }
  location = /robots.txt { access_log off; log_not_found off; }  
  

  Next we add the Archive plugin to Roundcubemail.
  You'll need to edit /var/www/roundcubemail/config/config.inc.php and add archive to the $config['plugins'] like below:

  $config['plugins'] = ['managesieve', 'password', 'zipdownload', 'enigma', 'archive'];
  

  You''ll have to add the Archive folder while in Roundcubemail, and set it up as a special folder.

  Lastly we'll need to change the Vim color scheme to desert. The default dark blue color scheme is very hard to see.

  echo -e "colorscheme desert" >> /usr/share/vim/vimrc
  

  That should do it for upgrading to SlackerMail v0.35.0.

• Upgrade from v0.34.1 to v0.34.2

  wget https://the-slacker.com/download/fail2ban-1.0.2-x86_64-1_SBo.tgz
  upgradepkg fail2ban-1.0.2-x86_64-1_SBo.tgz
  rm fail2ban-1.0.2-x86_64-1_SBo.tgz
  

  Disable PubkeyAuthentication in /etc/ssh/sshd_config - Optional

  sed -i "/#PubkeyAuthentication yes/c\PubkeyAuthentication no" /etc/ssh/sshd_config
  

  That should do it for upgrading to SlackerMail v0.34.2.

• Upgrade from v0.34.0 to v0.34.1

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Upgrade Nginx to v1.23.2, if using Nginx as your web server:

  Important! Make sure to backup your /var/www/html/index.html file before you upgrade Nginx, because it will overwrite that file.
  
  wget https://the-slacker.com/download/nginx-1.23.2-x86_64-1_SBo.tgz

  ./netdata-v1.45.2.gz.run --accept
  rm netdata-v1.45.2.gz.run
  

  Update time at boot because sometimes time is set wrong at boot, with echo command below:

  echo -e "/usr/sbin/ntpdate pool.ntp.org >/dev/null 2>&1" >> /etc/rc.d/rc.local
  

  That should do it for upgrading to SlackerMail v0.34.1.

• Upgrade from v0.33.0 to v0.34.0

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  Upgrade rust16 to v1.76.0:

  wget https://the-slacker.com/download/rust16-1.76.0-x86_64-1_SBo.tgz
  upgradepkg rust16-1.76.0-x86_64-1_SBo.tgz
  rm rust16-1.76.0-x86_64-1_SBo.tgz
  

  Change user amavis shell from /bin/bash to /bin/false:

  chsh -s /bin/false amavis
  

  Change user netdata shell from /bin/bash to /bin/false:

  chsh -s /bin/false netdata
  

  Stop restarting Dovecot and Postfix in /etc/rc.d/rc.local:

  Edit /etc/rc.d/rc.local and delete "Dovecot restart" and "Postfix restart" lines. No need for restarting.
  

  Remove package ModemManager - Not needed:

  removepkg ModemManager
  

  Add a cron.daily job to free up memory:

  echo '#!/bin/sh
  # Free up memory
  sync && echo 3 | sudo tee /proc/sys/vm/drop_caches' > /etc/cron.daily/free-mem
  
  chmod 0755 /etc/cron.daily/free-mem
  

  If Apache is used as web server, and you have Netdata installed:

  Edit /etc/httpd/extra/httpd-info.conf and change example.com to your domain name, and uncomment "#ExtendedStatus On".
  This is to let Netdata get server-status.
  

  If Apache is used as web server, and you have Fail2ban installed:

  Add fail2ban filter config file for apache-4xx jail. (left out by mistake)
  
  echo '[Definition] 
  failregex = ^<HOST>.*"(GET|POST|HEAD).*" (404|444|403|400) .*$ 
  ignoreregex =' > /etc/fail2ban/filter.d/apache-4xx.conf
  

  That should do it for upgrading to SlackerMail v0.34.0.

• Upgrade from v0.32.0 to v0.33.0

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  First update /etc/amavisd.conf as below:

  Change $max_servers = 16; to $max_servers = 8;
  

  Then add the SlackBuild package libmspack v0.10.1alpha as required by Clamav v1.3.0:

  wget https://the-slacker.com/download/libmspack-0.10.1alpha-x86_64-1_SBo.tgz
  installpkg libmspack-0.10.1alpha-x86_64-1_SBo.tgz

  upgradepkg clamav-1.3.0-x86_64-1_SBo.tgz
  rm clamav-1.3.0-x86_64-1_SBo.tgz
  

  then upgrade Logwatch to v7.10:

  wget https://the-slacker.com/download/logwatch-7.10-noarch-1_SBo.tgz
  upgradepkg logwatch-7.10-noarch-1_SBo.tgz
  rm logwatch-7.10-noarch-1_SBo.tgz
  
  Then run the below echo command to recreate a new cron.daily job for Logwatch:
  
  echo '#!/bin/sh
  #Set logwatch location
  LOGWATCH_SCRIPT="/usr/sbin/logwatch"
  #Add options to this line. Most options should be defined in /etc/logwatch/conf/logwatch.conf,
  #but some are only for the nightly cronrun such as --output mail and should be set here.
  #Other options to consider might be "--format html" or "--encode base64", man logwatch for more details.
  OPTIONS="--output mail"
  #Call logwatch
  $LOGWATCH_SCRIPT $OPTIONS
  exit 0' > /etc/cron.daily/0logwatch
  
  Then make /etc/cron.daily/0logwatch executable:
  
  chmod 0755 /etc/cron.daily/0logwatch
  

  Lastly upgrade Netdata to v1.44.2:

  wget https://github.com/netdata/netdata/releases/download/v1.44.2/netdata-v1.44.2.gz.run
  chmod 0755 netdata-v1.44.2.gz.run
  ./netdata-v1.44.2.gz.run --accept
  

  That should do it for upgrading to SlackerMail v0.33.0.

• Upgrade from v0.31.2 to v0.32.0

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  First: Upgrade Roundcubemail to v1.6.6. Go to the official Roundcubemail upgrade web page for instructions on how to upgrade Roundcubemail.

  Next: If you are using Apache as your web server then edit the /etc/httpd/httpd.conf file and add the following for redirect to https, just below
  "Listen 80".

  RewriteEngine On
  RewriteCond %{HTTPS} off
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
  

  Next: Nginx was added as an option in SlackerMail v0.32.0, so if you want to switch from Apache to Nginx follow these instructions. Make sure
  to adjust the self signed or Let's Encrypt certs in /etc/nginx/conf.d/mailserver.conf.
  
  Next: Upgrade php-imagick to v3.7.0 with the commands below.

  wget https://the-slacker.com/download/php-imagick-3.7.0-x86_64-2_SBo.tgz
  upgradepkg php-imagick-3.7.0-x86_64-2_SBo.tgz
  rm php-imagick-3.7.0-x86_64-2_SBo.tgz
  

  Lastly: Upgrade Unrar to v6.2.12 with the commands below.

  wget https://the-slacker.com/download/unrar-6.2.12-x86_64-1_SBo.tgz
  upgradepkg unrar-6.2.12-x86_64-1_SBo.tgz
  rm unrar-6.2.12-x86_64-1_SBo.tgz
  

  That should do it for upgrading to SlackerMail v0.32.0.

• Upgrade from v0.31.1 to v0.31.2

  Make sure your server is up to date with latest patches and kernel with the commands below:

  slackpkg update
  slackpkg upgrade-all
  

  After the upgrade you should have Postfix v3.6.13 and kernel 5.15.145.

  Next update the /etc/postfix/main.cf file with the following to prevent SMTP Smuggling:

  # Prevent SMTP Smuggling
  smtpd_forbid_bare_newline = yes
  smtpd_forbid_bare_newline_exclusions = $mynetworks
  

  Next update the netdata.conf file (If you opted to install Netdata on initial install of SlackerMail):

  wget https://the-slacker.com/download/netdata.conf
  mv -f netdata.conf /opt/netdata/etc/netdata/
  

  Then create the netdata cloud.conf file to opt out of the netdata cloud if you want to.

  echo "[global]
      enabled = no" > /opt/netdata/var/lib/netdata/cloud.d/cloud.conf
      
  Then change ownership of cloud.conf:
  
  chown netdata:netdata /opt/netdata/var/lib/netdata/cloud.d/cloud.conf
  

  Lastly upgrade OpenZFS (if you opted to install OpenZFS on the initial install)
