Relaying to two servers


Feb 5, 2019
I've been playing a bit with PMG, got it to work and now toying with it :)

Been reading this post 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 :
Host :
port : 25
Use MX : checked
