Relaying to two servers

[Aethyc]

Hello,
I've been playing a bit with PMG, got it to work and now toying with it

Been reading this post https://forum.proxmox.com/threads/redundant-servers-and-load-balancing-using-mx-records.73/ but I think it applys to incoming mail ?

Is it possible to relay a domain to two different servers ?

Public DNS MX1
|
PMG -------> mailserver1
|------------> mailserver2 if 1 is down

If I use a private DNS server containing the MX records pointing to the internal servers on PMG, am I correctly assuming this config should work as I imagine it ?
Transport config :
Relaydomain : mydomain.com
Host : mydomain.com
port : 25
Use MX : checked

Sounds correct.

Will try to make some time to test it

Finally tested it !
Works like expected
