Mark,

I previously had a duplicate delivery issue with a single user's account and
it turned out that the user's username/Maildir/.qmail file had been
corrupted. I restored the file and the problem went away. 

Regards,
Tim

2 copies of messages are usually a result of the message being in the
SMTP-processing-process (if that makes sense) too long. What I usually see
is when spamassassin, clam, or some other process (like reverse DNS
checking) takes too long. Since you migrated to Cent5, I have to ask what
your CPU and memory situations are. Cent5 is very memory hungry, 
especially when compared to Cent4.x.   I have a suspicion that when 
performing some checks that it's swapping to disk, which induce too long of
a latency in the process and cause the SMTP daemon to think the message "got
lost" somewhere and try and deliver it again.
