Incoming mail - unknown server error
« on: August 29, 2021, 04:52:32 PM »
Hey guys,

I am going crazy. I added a new domain on my pre existing server and can't get incoming mail to work. On this server there are already 3 domains with working emails and all the mailboxes on this domain can't receive anything.

DNS is setup exactly as the other domains. Emails reach the server and end up in the queue without being delivered to the mailboxes.

Here is the log:

Hi,

strange because this line shows me it has been sent:
Code: [Select]
Aug 29 18:49:32 tmip postfix/smtp[3223]: 5F29A20736: to=<user@receivingdomain.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=5.8, delays=0.14/0.02/0.02/5.6, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as E879B21C71)
have you tried to reboot the server since you added the new user?
