I have 2 primary mailservers - SIMS & AMS. Both have MX records with same priority to the same domain. I am trying to use SIMS as a backup, but I have a problem.
The MX records are:
MX 10 mail.domain.com
MX 10 mail2.domain.com
MX 20 mail3.domain.com
My question is - the 1st primary server has a router entry domain.com = mail.domain.com.
I am having problems since adding the 2nd primary server. Should that router entry be taken out?
That depends...
What exactly do you mean by 'primary' mailserver? If you are seeking a way to have mail delivered to mailboxes on 2 different machines, you have a logical problem: there's no standard way to force that behavior.
One important thing to understand about SIMS is that it has a domain name that is special, set in the general settings. it WILL NOT look to DNS for its own identity. Usually that name should be a fully qualified domain name with an A record that points to an IP address by which the outside world can get to that SIMS machine. That name should also be what you use in an MX record. If your SIMS machine is in fact mail.domain.com (both by DNS and by the SIMS setting) and you have that router entry, then all [EMAIL PROTECTED] addresses should deliver to local mailboxes.
I hope that provides some basis to help you figure out your problem. I'm not clear on exactly where you want mail to go and how you hope to get it there, or just what trouble you are having on which machine, so it's hard to be any more specific...
