I have a mail server with postfix + dovecot lookup to Active Directory for user authenticaiton and mailbox and deliver mail to virtual mailbox (dovecot) User authentication for IMAP/POP are working well but now I want to enable SMTP authentication with Active Directory.

I have no clue that where to start with postfix to do that, can anyone give me a hint / guide?

Thanks in advance!


Sorry, I don't know what's wrong with me.

Acttually, what I wan to ask is with kind of that setup, how do I enable auto forward email of a user to another email address when he receive new email. Postfix use alias to forward email of user (IIRC) but with virtual user like this setup virtual_alias_maps is use for mail group (mail list) so I have no idea. Is postfix can lookup from multi maps as specially in this case: virtual_alias_maps?

Sorry for dumb question, maybe I need rest when post it.

  • Is postfix can lookup from multi maps? Yes. Do you mean like this answers? – masegaloeh Nov 13 '14 at 6:05

For authenticated outgoing SMTP traffic you want to use the dovecot SASL in postfix as described here: http://www.postfix.org/SASL_README.html#server_dovecot

I didn't quite get if your delivery to dovecot is working or not. If you currently don't receive mails from postfix in dovecot, then follow this dovecot wiki article: http://wiki2.dovecot.org/LDA/Postfix#Virtual_users

  • Thanks for the answer, I'm busy so not try this immediately. Will let you know the result. At the moment, I can receive mail in dovecot IMAP/POP3. – Lê Hồng Việt Nov 11 '14 at 4:32
