Hello, I have different aliases configured under the same domain, say:
ali...@domain.tld ali...@domain.tld ali...@domain.tld which forward an email to the same mailbox, say: mail...@domain2.tld I have tried the following experiments.. EXPERIMENT 1: mail...@domain2.tld is the mailbox ali...@domain.tld (i.e.: the aliases above are all aliases of the same email address ali...@domain.tld) ============ I have a postfix mail server (Postfix+MySQL+Courier-IMAP+Maildrop). In the mailbox for ali...@domain.tld I saw three copy of the same message: one for each alias. Every one has the same message ID. EXPERIMENT 1: mail...@domain2.tld is NOT the mailbox ali...@domain.tld ============ The domain domain2.tld is managed on a different mailserver. It a MS Exchange mailserver which is not managed by me. When I get the messages on my MS Outlook with Windows protocol, I get only one message with three recipient: ali...@domain.tld ali...@domain.tld ali...@domain.tld Now, I have the following questions: 1) Why is there this different behavior in the situations above? 2) Who collapse the three email into one in CASE 2? The MTA or the MUA? 3) Is it possible to get the behavior on postfix post office while download messages with POP3/IMAP protocols? Thanks, rocsca
