Hi there,

    I was wondering.. Say I have atleast two mail servers on two different networks, in different, locations mainly for redundancy...
In DNS I have:

MX 10 primary.domain.com
MX 20 secondary.domain.com
MX 50 teretiary.domain2.com

If someone sends mail to userdomain.com and primary server is down, it'll go to userdomain.com on the secondary server...
How would I configure it so that, once primary.domain.com is back up, secondary will send that mail back to primary so users on that host can simply check their mail there? This way, mail is never lost so to speak. In other words, I'd like to have the secondary and teretiary server(s) etc.. as mail holders or backup mail servers.

I've tried looking in the FAQ, etc.. But couldn't find the right answer I'm looking for. Maybe it is there and I just missed it or something, but any help/advice/recommendations on this would be greatly appreciated!

Thanks!
