Another  option  would  be  to  periodically re-import the user registry
data.

Here's  where  I've  got  some questions. When the primary does down are
you/they expecting to be able to see the e-mail that was received on the
primary when you are connecting to the backup?

And  in reverse, when the primary comes back up is the expectation to be
able  to  see  e-mail  that  was  received  on the backup when you start
connecting to the primary again?

If  people  will  accept  e-mail stored on the primary being unavailable
when  the  primary  is  down  and  e-mail  received  by  the  backup not
automagically appearing on the primary the task becomes a lot simpler.

It  would  make  sense  to  have  an authoritative slave running in your
backup  data  center.  You'll automatically get updates you make on your
master  nameserver  and  some of the cost of backup data center could be
assigned  to  DNS backup (although a 'dig' on todhunter.com shows you're
pretty well covered in that respect).

Keep in mind that any network hiccups that prevent someone from reaching
the  primary  will  cause  them  to  attempt  to reach your backup. Also
spammers  will  often  go  after lower priority MX's with the assumption
that they're less protected.

That would certainly cut down on spammers going after the backup :-)
