If i am sending a mail to group1 and group2. It is going two times a single mail to the user1 mailbox. But in dovecot it is not eliminating since it has the same message-id. Previously i was able to accomplish this task with cyrus duplicate elimination.
"two times a single mail to the user1 mailbox" actually I do expect that the MTA detects the duplication of the two aliases and does NOT send the mail two times to user1.
Yeah, I think that's what I answered before too. Dovecot currently has no duplicate elimination code.
(I hate the whole concept of dropping incoming messages as duplicates based on Message-ID. I would definitely want it disabled for my own mails, for example that would mean I couldn't filter messages to mailing lists based on List-ID: header, because the first mail usually comes directly from the other user, and then the second mail with the List-ID: would get dropped.)
