Unable to send mail - Android and IOS

[Aerobaticrug]

I'm running Plesk 12.0.18 update 39 on Centos 6.6 with postfix and courier-IMAP

However I can't send emails from mobile devices or outlook - the security settings are invalid, I've tried all 4, SSL, SSL/TLS Accept all certs, Start TLS etc.

Can anyone point me in the right direction?

Hi Aerobaticrug,

in most cases of your described issue, the cause are wrong/incorrect cipher usage and/or misconfigurations for postfix or courrier-IMAP. Keep in mind, that it might be sometimes a good idea to temporary change the standard log - level ( defined in the depending configuration files ), to get a more detailled output of issues/failures/problems/errors-

To help to investigate you issues, please include error - logs and depending configuration files:
