We use sqlgrey as a policy daemon for greylisting. It runs on both our
mail servers with a shared database on one of them. If the database is
unavailable for some reason on the main server the backup rejects mail
with "451 4.3.5 Server configuration problem" Is it possible to change
the default to accept the mail if the policy daemon fails. Most of our
users would prefer a bit of extra spam to losing genuine mail.
Maybe you should consider having a master db on one of the mail servers
and a slave db on the other one and have the data be replicated to the
slave automatically.
This way you can minimize the risk to have either mail server to reject
email just because the to servers aren't connected.
Setting up mysql replication is of course off topic here.
