Not too clear from the subject and probably a lame idea.

Situation: We have a system (MX1) that is having hardware problems.
Currently they are irritations but we want to rebuild the system before
it really crashes. There are actually two systems so there is back up
(MX2) in case there is a failure.

We created another system (MX3) and added it to the DNS records with a
priority the same as MX2 and gave MX1 a really low priority hoping to
slowly reduce traffic to it.

It is going too slowly! So I was thinking instead of just shutting it
down it would be nice to the tell the connecting systems to go to the
other system then refuse to accept the mail. After a day or so shout it
down.

Is this possible? If so what is it called? (I'm completely at loss here
for terms to search with.)

Thanks,
Rod
