Hiya :)

OK I'll clarify :) The new 1U boxes will use the same config as the
existing mail server, including rejecting users that dont exist. Our
amavisd settings will also be stored in LDAP, so that look up will take
place anyway.

Also, we have three redundant LDAP servers. One primary write only and
two read only, which are speedy. LDAP runs our entire network, and we
have hourly backups of the entire data, and spares that stand by :) I
think we're covered from LDAP's end. Its honestly the simplest setup
I've ever worked with. Once you understand it, of course.

regards,

Matt
