By the way, why do you have a backup MX? [snip]
He's right. There's no reason for this anymore. All MX's should
be precisely equivalent in terms of their accepted email addresses
and their anti-spam rulesets. The primary tools of competent,
professional system administrators are your friends here: use
make, rsync, and friends to ensure that they're kept identical
at all times...and use things like virtusertable entries to handle
the internal plumbing necessary to route mail as needed.
While I agree, it may still be advantageous to have inbound email come
to one server over another, so it's not inherently wrong to consider one
a "backup", as long as the configuration is functionally similar.
But the traditional "just accept everything" backup, as a concept, needs
to go away.
