Hello there!
I have a remaining problem with Dovecot or Postfix. I have searched the forums and searched the interwebs but nothing helped so far so I hope you guys may be able to help me.
I have a Virtualmin/Usermin/Webmin Server. It contains a number of subdomains and the corresponding email addresses connected to their users.
I have installed SSL Certificates and connected them to Dovecot and Postfix, I have also been able to connect now with an external mail client, I get the folders and their contents. I can send out emails, but
I cannot receive emails.
They don’t show up in the Webinterface.
This is the /etc/log/mail.log contents:
postfix/error[3178]: 9B19744BDD: to=<user- domain.tld@x.xxx.xx.x>, orig_to=<user@domain.tld>, relay=none, delay=0.17, delays=0.08/0.05/0/0.04, dsn=5.1.3, status=bounced (bad address syntax)

Any suggestions?
I’ve found the answer which is also connected to your answer Ilia! I had to put the following line into the main.cf to make the ip address readable, since I couldn’t change the routing towards the domain assigned by my provider:
