Hi everyone: I'm using postfix as MTA in a lot of servers. I usually use aliases to forward messages from one account to another, or use BCC (sender_bcc_maps and recipient_bcc_maps) to copy messages to other accounts.
A couple of customers asked me to configure the system to save only a copy of external sent/received messages to an account. Our MTA receives mail for domain1.com, domain2.com and domain3.com but he needs to save a BCC of every sent/received mail except those between these domains internally. I was thinking something like this: Sender Recipient Action [email protected] [email protected] (none, don't BCC) [email protected] [email protected] (BCC to [email protected]) [email protected] [email protected] (BCC to [email protected]) [email protected] [email protected] (none, don't BCC) I would want to achive this at MTA level, I mean using Postfix. Is it possible? I was searching something similar that really works but I had no luck. Thanks
