Hello to everyone I'm trying to do full mail archiving and i think my server behave strange. For example: I have - domain1 and mailboxes - mailbox1@domain1 - mailbox2@domain1 - mailarchivemailbox@domain1 Inside mailbox1@domain1 and mailbox2@domain1 I set up mailarchivemailbox@domain1 as "Send copy to" and "Send outgoing BCC to" mailarchivemailbox@domain1 receiving 3 identical email to INBOX when mailbox1 sends email to mailbox2 But when mailbox1@domain1 sends email to not localdomain - everything works fine. Then I added line to master.cf like this to avoid double messages but it doesn't work. Code: smtps inet n - - - - smtpd -o receive_override_options=no_address_mapping Please anyone give me any suggestions?
This is what happens when you send an email from a to b where both are local domains in the setup you made: 1) There is the original mail which will go from A into mailbox b. 2) You configured outgoing bcc, so during sending, a copy is sent to the archive. 3) As you configured incoming copy, another copy of the mail is sent to the archive during receiving. Sending and receiving are two different actions and as you configured your system to create a copy during send and another during receiving, you must end up with 3 copies of this email on your server. Postfix can not deduplicate the email as the send copy to is done by dovecot and not postfix.
A -> B send = 1st mail in archive B received mail from A = 2nd mail in archive where is from 3rd email in archive? I can't understand a logic excuse me is there some mechanism or trick to kill duplicates in mailarchivemailbox@domain1 ? is it possible to modify logic to kill duplicate mail if sender and receiver are local domain mailboxes?
Please mark thread as SOLVED probably it will help someone. In file /etc/postfix/main.cf I changed line: Code: sender_bcc_maps = proxy:mysql:/etc/postfix/mysql-virtual_outgoing_bcc.cf to Code: sender_bcc_maps = hash:/etc/postfix/sender_bcc and added line: Code: recipient_bcc_maps = hash:/etc/postfix/recipient_bcc and created two files with text inside: /etc/postfix/recipient_bcc Code: mailbox1@domain1 mailarchivemailbox@domain1 mailbox2@domain1 mailarchivemailbox@domain1 /etc/postfix/sender_bcc Code: mailbox1@domain1 mailarchivemailbox@domain1 mailbox2@domain1 mailarchivemailbox@domain1 after that reindex hash files Code: postmap /etc/postfix/recipient_bcc postmap /etc/postfix/sender_bcc and restart services or reboot server: Code: systemctl restart dovecot postfix
Personally, i would add this to postfix cleanup-service. Code: cleanup unix n - - - 0 cleanup -o sender_bcc_maps=hash:/etc/postfix/archive_maps -o recipient_bcc_maps=hash:/etc/postfix/archive_maps /etc/posfix/archive_maps: Code: @domain [email protected].
