We have route.cfg set up to send mail for some destination domains direct instead of through the default relay.
One of the destination domains we want to add to route.cfg has multiple MX hosts they can receive mail on.
Is it possible to add multiple host IP addresses for a single destination domain in route.cfg?
abc.com has mail receivers with MX records:
abc.com 3600 IN MX 9 10.0.0.25
abc.com 3600 IN MX 2 10.0.1.25
abc.com 3600 IN MX 2 10.0.2.25
abc.com 3600 IN MX 9 10.0.3.25
- is there a way to put all those into route.cfg for abc.com for resilience?
As I've read that route.cfg works in a similar manner to the hosts file, would a space separted list of IP addresses work?
