I have been slowly building a mail gateway, mg05.
I had working sending of email from my gmail account to
rlo...@mg05.cnm.edu and via virtualaliases it was passed into the
appropriate email server.
I noticed as I populated the virtualaliases table with more and more
lines from other gateways in production something broke.
I could no longer send to an address such as rlopez originating with
the local /usr/bin/mail.
The fix for that was to add this to /etc/postfix/main.cf:
append_dot_mydomain = yes
to allow appending cnm.edu to find fqdn for locally injected email.
That last change appears to have fixed that problem.
However now email sent from my gmail account to my rlo...@mg05.cnm.edu
is logged by postfix/error as "status=deferred (mail transport
unavailable)"
I do not comprehend how that last change has this side effect.
What am I missing?
