In the ongoing battle to eliminate spam (chuckle), I'd like to share my blacklists with my secondary MX.
Other than a manual hack, which would have to be redone at every upgrade, are there any plans to take advantage
of all the work we put into our blacklists?

Re: Share Blacklisting to backup MX

The latest iRedMail + iRedAdmin-Pro stores white/blacklists in Amavisd database (tables: mailaddr, users, wblist), so you can replicate this database to secondary MX.

Also, if you enable `relay_recipient_maps` in Postfix and replicate `vmail` database to backup mx, it will reject emails sent to unknown users.

BTW, we just fixed Backup MX setting in iRedAdmin-Pro, so with next iRedAdmin-Pro release, you can host mail domain as Backup MX.
