Upgrade iRedAPD

iRedAPD source code is hosted on BitBucket.

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.

• Download the latest stable release here: http://www.iredmail.org/yum/misc/ For example, iRedAPD-1.4.4.tar.bz2.
• Upload it to your iRedMail server. Assume it's /root/iRedAPD-1.4.4.tar.bz2.
• Extract downloaded package and execute upgrade script:

# cd /root
# tar xjf iRedAPD-1.4.4.tar.bz2
# cd iRedAPD-1.4.4/tools/
# bash upgrade_iredapd.sh

That's all.

Important notes:

• Plugin amavisd_wblist is required if you manage white/blacklists with iRedAdmin-Pro.

• It's recommended to enable plugin reject_null_sender in iRedAPD-1.4.4 or newer releases to prevent authenticated user sending spam as null sender.

• Since version 1.4.4, iRedAPD supports Postfix smtp protocol state END-OF-MESSAGE, so you can enable iRedAPD in Postfix parameter smtpd_end_of_data_restrictions like below:

  smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:7777, ...

  Currently, only plugin amavisd_message_size_limit works in END-OF-MESSAGE state, other plugins work in RCPT state.

• If you want to develop your own plugin for iRedAPD, please read document README_PLUGINS.md in iRedAPD source code.
