I just installed my first e-mail server, a Release 6.0.6_GA_2324.DEBIAN5 DEBIAN5 FOSS edition, with the archiving option using Postfix's always_bcc.
I am facing a situation wich I think is not exactly a problem, but it's been quite a pain. The thing is: when an internal user sends a message to an external user, only one message is archived, and this is fine. The problem is that the messages are been archived twice when exchanged internally (or more times when it's been sent to multiple internal accounts - one copy for each account). I understand that Postfix is archiving once for the message sent and again for each receiving account.
My question: is there a way to make Postfix archive the message just once, no matter how many people it is sent to?
