Hello,
I've setup Postfix, Dovecot with MySQL and PostfixAdmin like here:
https://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot-mysql/
on an Ubuntu 12.04 VPS.
I can send mails - so far so good.
Now I assume, that something is wrong with my rejection list. If I send
an email from a freemailer to any account I see this in the mail.info:
Sep 5 04:47:01 nudin1 postfix/smtp[26753]: 5F08712E005F:

I'm not perfectly sure about the hostname in the /etc/hosts ..
Does this need to be an actual domain name of one of the domains which
are served by this server?
Is there anything wrong in the main.cf?
Thank you in advance
Bye, Chris
