Maybe this is a little out of topic, but maybe some of you have experience with this.... What do you thing about chaining SPAM filters?, can this led to false positives faster?. Example: Internet ---> GW-Relay+Antispam (host1) ---> Antispam Appliance (host2) ---> MDA+Antispam (host3)
Sounds awful.
On our edge we have an SMTP server that verifies the inbound address exists and uses RBLs and Greylist. This delivers messages that pass to an internal SMTP server that uses CLAM (anti-virus) and SPAMAssasin (Anit-spam, to score messages). SPAMAssasin sits in its own VM (just so it is easier to update). The SMTP server can use an external content filter.
Thanks a lot for the input guys. This is a "customer requirement" as they "need" to justify those licenses paid in AntiSPAM appliances (more than one :s), I really don't like the added complexity and currently look for good arguments against this...
