Given the spate of postings concerning the use of milters recently, I
thought this information from Anthony Howe concerning sharing milter
information between gateways would be of interest to others on the list.
I will second the posts that have praised the effectiveness of milters as a
method of cutting off spam before it adds load to your gateways. If you're
looking to learn more about some of the different milters available drop by
An article which gives an interesting overview of milters can be found at

Install milter-sender on the 3rd server using an Internet host:port
specifier instead of the unix domain socket specifier, then specify in
the Sendmail config for the two MXes that they should consult
milter-sender via an Internet socket to the 3rd machine.
In this way you can centralise the cache used by milter-sender. NOTE
that a copy of the access.db should be found on the 3rd server or
accessible by NFS for B/W list support.
ANY milter (not just Snert milters) can be centralised in this manner,
since its a base functionality of libmilter and Sendmail.
See the milter-sender documentation and sendmail libmilter documentation
