postfix+mysql+courier on Fedora 12, all mail rejected after update.

[djanubis]

ISPC 3.0.1.6 used to work on Fedora 12, PHP 5.3.1 and MySQL 5.1.42, but after last yum update, mail is rejected with:

, relay=maildrop, delay=0.03, delays=0.01/0.01/0/0.01, dsn=5.1.1, status=bounced (user unknown. Command output: Invalid user specified. )

I checked every bit offered by various google sources and cannot find what is now broken.

Please post the maildrop line(s) of the master.cf file.

Hi djanubis,

I just solved this same problem on my Fedora 11 system. When yum updated my maildrop package, the update was not compiled with authlib enabled. I first ran `yum erase maildrop`, then I simply had to download the source (http://www.courier-mta.org/download.php#maildrop) and recompile it following the installation instructions.

I say simply, but it took me 4 hours to find this post that tipped me off to what the problem was:

Your `maildrop -v` should look something like this:

# maildrop -v

Thank a lot. It helps. Is there any other package that needs to be excluded from yum update ?
