Something I did last night must have screwed things up. This morning, /var/log/maillog shows the following: sendmail[1876]: starting daemon (8.13.4):SMTP+queueing@01:00:00 sendmail[1876]: NOQUEUE:SYSERR(root): opendaemonsocket: daemon MTA: cannot bind: Address already in use sendmail[1876]: daemon MTA: problem creating SMTP socket What could be causing this?
