This tutorial describes how to upgrade iRedAPD from 1.4.0 or later releases
to the latest stable release. It's applicable on all Linux/BSD distributions
supported by iRedMail.
/root/iRedAPD-2.4.tar.bz2.Attention
If you're running iRedMail with OpenLDAP or MySQL/MariaDB backends, upgrading from iRedAPD-1.6.0 or earlier releases requires MySQL root username and password, please get them before you run upgrade script.
# cd /root
# tar xjf iRedAPD-2.4.tar.bz2
# cd iRedAPD-2.4/tools/
# bash upgrade_iredapd.sh
That's all.
Known issues of SRS (Sender Rewriting Scheme) support
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.
Plugins
It's recommended to enable plugin reject_null_sender in iRedAPD-1.4.4
or later releases to prevent authenticated user sending spam as null sender.
Plugin amavisd_wblist is required for whitelisting and blacklisting.
