Both servers are nearly identically configured (just different domains
and users).
One has been running Wheezy several months longer, but they're both on
wheezy now, anyway.
I essentially set them up, initially, when running squeeze, according to
the instructions here:
https://library.linode.com/email/postfix/dovecot-mysql-debian-6-squeeze
although 1) they are not on linode (one is on contabo in germany, the
other is here in my office), and 2), they were both updated to Wheezy
since then (and configs for both dovecot and postfix had to be altered
at that time, but that was months ago for both, and both were working
until this morning).
They both use mysql (well, mariadb) auth for both dovecot and postfix.
I have confirmed that I can connect to the DB on either server with the
mail admin account configured in postfix.
Yet, I can not send mail.
I'm stumped.
They were working yesterday during the day. I ran aptitude update, then
safe-upgrade later in the evening.
Then today, they can not send mail.
As far as I recall, postfix was not updated yesterday.
Nor was mariadb, dovecot, or anything else I can imagine is significant
here. Aside from mail, the servers have slightly different software
installed. One received 1 update, the other 3.
I do not believe they were the same at all (as in the 1 update one the
first server was not the same as any of the 3 on the other).
Still, they're having apparently identical problems now, and the only
thing that has changed on either since they were working was running the
aptitude updates.
All the logs seem to be telling me is that SASL auth is failing,
which I know. They do not tell me why or wherein lies the failure.
