But that's not what the mail server is supposed to do.
% host -t mx debian.org
debian.org MX 10 klecker.debian.org
debian.org MX 0 master.debian.org
debian.org MX 5 murphy.debian.org
That's what it's supposed to do, and then try to deliver mail to master
(if master is down, try murphy (if murphy is down, try klecker (if klecker
is down, make a bounce))).
For example,
% vrfy -v apenwarr-survey@debian.org
vrfy 'apenwarr-survey@debian.org' at 'master.debian.org'
<apenwarr-survey@debian.org> is deliverable

This is intentional, that's what DNS round robins are for :)

This, however, is a problem. It's known to happen since not all of those
four update at the same speed... <sigh>
