[Dbmail] Mysterious issue with local email.

[Mark Ratering]

I'm having this really quirky issue with DBMail where mail between two 
specific users is not being delivered properly.  All other mail works 
fine.  In one case a message seemed to be cross linked.  the correct 
subject displayed but the message was another message entirely.  I am 
95% sure that postfix is not causing this.  Any and all help would be 
greatly appreciated.
