Replication question - cross replication?

[Nels Lindquist]

Hi, folks.

I'm setting up a high-availability mail server setup with two boxes that
will essentially be mirrors of each other.

If both are configured for local delivery, can I have them replicate
each other if I utilize UUIDs?

The idea would be to have identical copies of each mailbox on each
machine, regardless of which one accepted the mail initially.
