DB Errors [SOLVED]

[Daniel Hazelbaker]

Okay, after knocking down our mail server for an hour to track this 
down I have a solution.  I do not remember where, but somewhere when I 
was setting this up years ago I read that the method for delivering 
from postfix->procmail->spamassassin->cyrus was to have postfix deliver 
to procmail, and procmail instruct spamassassin to do its thing. Then 
to use the cyrus deliver program with "-a $LOGNAME -m user.$LOGNAME" to 
deliver the message.  Well what was happening is this:

Breakpoint 1, verify_user (user=0x0, domain=0x0, mailbox=0x100f8189 
"user.kristina", quotacheck=0, authstate=0x0) at lmtpd.c:554

This combination (user = null and mailbox != null and mailbox does not 
exist) would cause verify_user to pass userinbox (== null) to 
autocreate_inbox, which would strcmp without any error checking and 
segfault.

The solution seems to be to change the deliver line to just "-a 
$LOGNAME $LOGNAME" and it seems to work properly for everything.
