Sendmail and backup MX

[Steve Campbell]

I believe DNS does this if you have your secondary MX defined in DNS with 
equal or lower priority than the primary.

The primary will not accept mail as it's down.
DNS will direct mail to the secondary automatically.

I think this is all proper. I could be wrong though.
