Hi,

I have a mail server, nearly all of the users are using IMAP but few of them have to use POP3.
I would like to make a copy of every outgoing and incoming messages for the daily backup for my POP3 users.
Incoming is working smooth with procmail.
For some reason postfix made 2 copies of every incoming messages instead of outgoing if I am using sender_bcc_maps option.

I dug a lot to solve this problem, but I am stucked now.

Anyone could help me?


Thanks, Robert

can you not just manage your backups at a filesystem level? It's much nicer to handle this sort of thing at the lowest generic level possible.

Thats what I do.

Maing backups of every mailboxes, but because of POP3 the messages are sent by the user stored on the local machine.
I know I could make a rule on the local machine to send a copy but that is not an option.

I don't see how POP3 is relevant really. Sure if a mail arrives and they pull it off the server and delete it in error locally it's gone, but that's their problem, no? Generally most POP3 clients can be instructed to leave a copy on the server anyway. Am I missing something?

I said POP3 because of the settings, if you set up outlook as POP3 client the program wont copy anything to the server, just store it locally. Ofc you can set it to keep all incoming mail on the server but you can't do that with the outgoing emails.
Unfortunately I can't say "Ohh sorry the user deleted the message".

So my problem, I need a copy all of the outgoing messages on the server before the message leaves it.

Thats why I tried sender_bcc_maps but for some reason it makes a copy of incoming messages instead of outgoing.

Sorry if I misdirect you.

Any ideas?
