I have dovecot installed on Ubuntu 12.04. I am using Ispconfig3 to manage the virtual users. I have been through the http://wiki2.dovecot.org/TestInstallation
process and everything (except the ssl) works: I can log in using telnet. I can open the inbox.
However when I try to send an email to one of the accounts from gmail, the email gets returned from "Mail Delivery System" saying "unknown user: 'test'". Trying to receive mail using a client gives an authentication error.
There don't seem to be any relevant errors in /var/log/ mail.err or mail.log, exept: CB7D01242D5: to=<email@example.com>, relay=local, delay=0.49, delays=0.01/0.38/0/0.1, dsn=5.1.1, status=bounced (unknown user: "test")
One thing I am suspicious of is that I have not used a sub domain for my mail server and I am not sure if this causes problems. (Now or in the future).
What should I do to troubleshoot this further?
