Subject: [IMail Forum] '550 unknown user' errors for users who exist
Occasionally my server starts sending back '550 unknown user' when the
users exist. I believe that it returns this for all users on the system.
The most expedient way to fix the problem has been to reboot. However,
sending back a 550 unknown user for users that exist is *very* bad! I'd
like to figure out how to stop getting this message in the first place. Any
clues?

Peace is not the absence of war. Peace is the presence of a system for
resolving conflicts before war becomes necessary. War never creates peace.
