I have a mail system from Postfix, Dovecot, Amavis, Spamassin on a Debian Jessie 8.5.

Imap and pop3 work fine. Smtp port 465 over ssl sends fine, delivery is okay, but port 25 and 587 got the error "undelivery user unknown for all local recipient and internet mailboxes".

My master.cf is:

dovecot unix - n n - - pipe
    flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

  • Here a little bit of professionalist writing style would be needed. So that you answered your question, it is okay, but if you want others to invest effort to answer your question, it is much better if it seems well. – peterh Feb 17 '17 at 21:36

All start to work after adding these two lines in master.cf in postfix:

smtp unix - - n - - smtp -v -v
smtp inet n - n - - smtpd -v -v

postfix/smtpd - This is typically the SMTP daemon process for handling incoming mail and routing to the appropriate internal location. postfix/smtp - This is typically the SMTP daemon process for delivering mail out to the world.

smtp inet n - n - - smtpd this line tell postfix to send mail via 25 port

  • It is a little bit "magician answer": it says: "do X, Y will happen", but there is no explanation. Good answers aren't simply a snippet, they explain what it does and how. – peterh Feb 17 '17 at 21:33

  • Not in a comment, extensions to an answer should be edited into the answer. Furthermore, you can (should) accept also your own answers to your own questions. – peterh Feb 18 '17 at 19:29
