Bob:
I am using postfix on an Ubuntu 16.04 system. I have also installed
dovecot as my mail server. I am able to send mail, I am also able to
check my mx setup from outside my domain (mxtoolbox) and it tells me
there is only one issue with a banner mismatch in my reverse dns. The
problem is I cannot receive mail. The system returns a "user not found"
or "user unknown" message in the logs. I checked my home directory and
there is a Maildir in that directory. I do not have virtual mailboxes
set up. Any help would be appreciated.
On this list, in addition to your opinions, we also want to see hard
evidence in the form of "postconf -n" command out and logfile records,
perhaps anonymized, and never with verbose logging turned on.
So, I now know what you need to see and will send it.
