2 iredmail mailservers behind haproxy
-
Hello all. i already have a quite big infrastructure.
2 pfsense HW in failover ans sync.
i want to create 2 new servers with 2 iredmail mailserver on them.
What i want is HaProxy will redirect tcp requests from internet to one of the 2 mailserver in loadbalance failover roundrobin.
i already did the frontend answering tcp 25,143,587 but these doesnt go to backend as expected.
i did not NAT, just firewall rule on wan and haproxy front and backend
Hope you'll help me
thanks -
@Tony-Soprano It is not very easy to Proxy SMTP and IMAP with Haproxy and will cause adnormal problems. But you would need to enable Proxy in Postfix main.cf.
Personally I would not bother.
I would use Haproxy for Webmail & ActiveSync on Port 443 then for SMTP 25. 587 and IMAP 993 I would put them under NAT instead.
Depending how many Static IPs you have too.
I would configure mx1 on Public IP 01 and mx2 on Public IP 02 then configure relay from mx2 to mx1. Make sure you have PTR Records added by your ISP too.
Regards
