Postfix/smtpd problem

Postby Sysadmin1 » Tue Jun 12, 2018 8:04 am

Hello,
just installed Zimbra 8.8.8 on Centos 7.4. With DNS Windows server inside local network. Web client work well. Can send and receive the mails to external mail servers.
But can't connect mail client (tried with Thunderbird and Opera mail).
Zimbra log:

Any ideas?

So found out the answer myself.
In my case (no zimbra proxy installed, standard certificate generated bt Zimbra automaticly during the instalation process)
Port for imap should be 7143 and 25 for smtp.
STARTTLS for encription and standard password.
