On two different systems: Ubuntu 18.04 fresh & auto install - works fine with the exception of send/receive emails - please help! Connection ok to Roundcube but not send/receive Email client (windows 10 client and thunderbird) by pop3 or imap just connected and grab only the welcome roundcube email! Port 25 open (and other ports), work with other control panel! On the other control panel work everything.

Seems as if your mail client tries to use a deprecated SSL protocol (SSLv3): https://github.com/tomav/docker-mailserver/issues/705 If your client does not support recent encryption methods, then change the lines: smtpd_tls_protocols = !SSLv2,!SSLv3 smtp_tls_protocols = !SSLv2,!SSLv3 in postfix main.cf file to: smtpd_tls_protocols = !SSLv2 smtp_tls_protocols = !SSLv2 and restart postfix.

Please post the postfix main.cf and master.cf file of your server. And as a side note, there is no official automatic installer for ISPConfig, the supported and tested way to install ISPConfig are the perfect server tutorials.

Remove the # in front of the smtps and submission line in postfix master.cf and restart postfix. If an auto installer works depends heavily on the base system, if the base system is really clean and unmodified and exactly as the auto installer needs it, then auto-installers will work. But many ISP's modify their base images so they are not exactly the same than a normal clean ubuntu install and then auto installers tend to fail. That's why we recommend the manual step by step installation as its faster in most cases than using an auto installer + having to debug the auto install later to fix it.
Was fresh install on my server(s)... Now the mail has gone from Roundcube (oh yeah), due to settings arrived in my google spam (later I resolve this) But not from client (windows 10 client)...

If that's the lasts ending attempt, then the tls protocols seem still to be too new for your windows client. Try to change the lines: smtpd_tls_mandatory_protocols = !SSLv2 smtpd_tls_protocols = !SSLv2 smtp_tls_protocols = !SSLv2 to smtpd_tls_mandatory_protocols= smtpd_tls_protocols= smtp_tls_protocols= and restart postfix.
So... After some weeks in production... The setup works well in multiserver enviroment... Sites on slave servers sometime have a time loading and sometime just not works, sometime faster. Just on slaves. And with not a lot of zones/sites. But, some errors/warnings on phpmyadmin login, witch are not displayed anymore by added >>sql-mode=""<< under [mysqld] block in /etc/mysql/mysql.conf.d/mysqld.cnf and this was mandatory for older versions of osCommerce. One bug... Mysql (fresh without mods) report databases 0kb on admin dashboard, after this little mod simply show correct info...??? Another one: Cron backups works, but only at 00.00h. If I choose another same hour on all servers work or not. Sometime just make it at 00.00, sometime at my hour. Thanks!
