I've created an SMTP service application that archives emails by some criteria. Now I need to make postfix send a copy to my service when it receives some mail.
Most obvious way to go would be to use "content_filter = my_service". Problem is, using content_filter I will need to re-send the mail back to postfix from my service, and I don't want to do that. Is there a way to make postfix clone, not redirect, the messages to my SMTP service?
Thanks in advance.
