It's late and I've had a long day, so forgive me if I overlooked this
from someone else mentioning it. Have you checked the permissions on the
sasl_passwd and sasl_passwd.db file?
When I updated today, one machine stopped working sending mail, and the
other one was fine. For me, I found the relayhost commented out, and I
have no idea why. On the working machine, everything was fine.
Given the strange happenings of updating today, I'd check the
permissions on the sasl_passwd files. They should be 600. If that
doesn't work, did you simply try to regenerate the sasl_passwd.db file
after the permission is correct?
postmap hash:/etc/postfix/sasl_passwd
The last update from 4.2 -> 4.3 made my relaying stop working, and all I
had to do was regenerate the password file and life was good again.
Whatcha think?
