Corrupted messages Postfix

Hello David,

This problem you have may be stemming from the change of locking
scheme in Postfix 2.10. It was also a problem (in the past) when we
did the two-postfix deferred queue thing to implement MailScanner
(prior to the hold queue thing we usually do now).
Check wether your postfix is using fifo or unix locks in master.cf,
and consider going back to fifo in that (with appropriat restart of
Postfix afterwards, of course)... OR change MailScanner.conf
accordingly and restart MailScanner (setting is "Lock Type").

I would think it fairly safe&easy to do the PF change.

Cheers
