ubuntu 8.X maildrop
I just did a fresh install onto Ubuntu 8.10 ran into 2 problems that shut down the mail system for ispconfig..
On sending an email to a test account.. /var/log/mail.log: Jan 30 09:04:47 XXXXXX postfix/pipe[22066]: 1D8CC781DB: to=test@XXXXXXXXX, relay=maildrop, delay=0.68, delays=0.27/0.02/0/0.39, dsn=5.1.1, status=bounced (user unknown. Command output: Invalid user specified. )
checking maildrop: maildrop -d test@XXXXXXX Invalid user specified.
fix: apt-get remove courier-maildrop apt-get install maildrop
Why: latest courier-maildrop is not compiled with mysql.. yeahhhh..
this moved me to error number 2, when sending the next test email: Jan 30 10:49:20 XXXXXXXXX postfix/pipe[9203]: 868AD7805F: to=test@XXXXXXXXXXXX, relay=maildrop, delay=0.24, delays=0.06/0.02/0/0.16, dsn=5.1.1, status=bounced (user unknown. Command output: ERR: authdaemon: s_connect() failed: Permission denied Invalid user specified. )
Fix: chmod 4755 /var/run/courier/authdaemon
After that the mail system worked fine.
