We received few reports from clients that Outlook for macOS may trigger some
unexpected smtp errors, and caught by the Fail2ban filter rules shipped by
iRedMail, so we decide to remove the filter rule used to match Postfix log
lost connection after EHLO.
Please follow commands below to get the updated filter rules.
cd /etc/fail2ban/filter.d/
wget -O postfix.iredmail.conf https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/samples/fail2ban/filter.d/postfix.iredmail.conf
wget -O dovecot.iredmail.conf https://bitbucket.org/zhb/iredmail/raw/default/iRedMail/samples/fail2ban/filter.d/dovecot.iredmail.conf
Restarting Fail2ban service is required.
After you have iRedAPD upgraded to version 2.5, it will listen on 2 new network ports: 7778 and 7779. They're used by Postfix for SRS (Sender Rewriting Scheme). For technical details of SRS, please read this paper: The Sender Rewriting Scheme (PDF).
To enable SRS support, please add parameters below in Postfix config file
/etc/postfix/main.cf (on Linux/OpenBSD) or /usr/local/etc/postfix/main.cf
(on FreeBSD):
sender_canonical_maps = tcp:127.0.0.1:7778
sender_canonical_classes = envelope_sender
recipient_canonical_maps = tcp:127.0.0.1:7779
recipient_canonical_classes= envelope_recipient,header_recipient
Reloading or restarting Postfix service is required.
Known Issues
Sender addresses will always be rewritten even if the mail is not forwarded at all. This is because the canonical maps are read by the Postfix cleanup daemon, which processes mails at the very beginning before any routing decision is made.
Postfix will use rewritten address in the Return-Path: header, if you
have any sieve rules based on Return-Path:, it MAY not work anymore and
please update your sieve rules to match rewritten address.
