I had a problem with setting second node as backup mx. When I did it, postfix always send email to dovecot and dovect return error "Unknown user".

Same issue was reported here: http://www.iredmail.org/forum/topic4160 … up-mx.html

I think I found problem in SQL query for transports.

/etc/postfix/mysql/transport_maps_domain.cf

query       = SELECT transport FROM domain WHERE domain='%s' AND active=1

This query apply transport field also to domains which are relay_domains, domains with backupmx = 1. My opinion is backupmx domain should be only received by postfix, stored in queue (maybe checked by amavis) and then resent to domain primary mailserver based on DNS mx records for domain, no transport magic.

So i changed this query to

query       = SELECT transport FROM domain WHERE domain='%s' AND active=1 AND backupmx = 0

and now it works.

BUT i just look into

http://www.iredmail.org/wiki/index.php? … 6-hotfixes

Can you please tell me what is wrong with this ? Before I put mailserver into production.

Thank you.
