Upgrade from v0.41.0 to v0.42.0
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
./netdata-v1.46.1.gz.run --accept
rm netdata-v1.46.1.gz.run
```
Upgrade Rust16 to v1.79.0.
```
wget https://the-slacker.com/download/rust16-1.79.0-x86_64-1_SBo.tgz
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:
```
wget https://the-slacker.com/download/nginx-1.26.1-x86_64-1_SBo.tgz
upgradepkg nginx-1.26.1-x86_64-1_SBo.tgz
rm nginx-1.26.1-x86_64-1_SBo.tgz
```
Upgrade Netdata to v1.45.6:
```
wget https://github.com/netdata/netdata/releases/download/v1.45.6/netdata-v1.45.6.gz.run
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

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.

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) .*$

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)

wget https://the-slacker.com/download/openzfs-2.2.2_5.15.145-x86_64-1_SBo.tgz
upgradepkg openzfs-2.2.2_5.15.145-x86_64-1_SBo.tgz
rm openzfs-2.2.2_5.15.145-x86_64-1_SBo.tgz

That should do it for upgrading to Slackermail v0.31.2 from v0.31.1
