Good day, everyone. Could you please tell me how to add IP addresses to the whitelist? Let me explain the situation: we are sending emails for distribution, but the emails are not reaching our mail server, Mailcow. I understand that they might be getting blocked somewhere or not arriving at all, as emails to external addresses do arrive.

Check for docs if some of those solution is suitable for you.
A) 
Per user settings docs.mailcow.email
B) For domain wide docs.mailcow.email
C) Server wide postscreen only docs.mailcow.email
Have something to say?

I tried to add the IP addresses to the postscreen. Now I will attempt to send the newsletter as well and check the results and let you know about them.

You will never know if you don’t look at the postfix log files (or the logs of the server sending the mails)
