New releases of iRedMail + iRedAdmin-Pro are scheduled to be released in November, after OpenBSD 5.8 release and new Ubuntu releases (hopefully).
It's not recommended to try the latest iRedAdmin-Pro development edition right now, because several components are not stable yet. If you're interested in giving it a try, i summary the steps below, hope it helps you make the decision.
*) Upgrade iRedMail to the upcoming iRedMail-0.9.3 by following this (DRAFT) upgrade tutorial:
http://www.iredmail.org/docs/upgrade.ir … 0.9.3.html
if you're not running iRedMail-0.9.2, please upgrade your iRedMail first. All upgrade tutorials are available here:
http://www.iredmail.org/docs/iredmail.releases.html
*) During upgrading iRedMail, you need to upgrade iRedAPD to the latest iRedAPD-1.7.0. it hasn't been released yet, but you can check out the latest development edition.
Important things are:
1) iRedAPD requires a new SQL database `iredapd`, used to store throtte settings (and throttle tracking info).
2) iRedAPD requires a new SQL table `amavisd.outbound_wblist`, used to store white/blacklists for outbound emails.
Once you have iRedMail-0.9.3 and iRedAPD-1.7.0 running, it's ok to upgrade iRedAdmin-Pro as usual (run 'tools/upgrade_iredadmin.sh').
WARNING: as mentioned above, both iRedMail + iRedAPD + iRedAdmin-Pro are still under development, something may be changed in final release, the changes between current development phase and final release will not be covered in iRedMail upgrade tutorials.
