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.
Wait, how can you say it sounds awful when you are doing EXACTLY the same thing via a VM?
What Adam describes is quite typical of an anti-spam setup, but not at all like Ciro's setup. Judging by his description, Ciro has three independent anti-spam filters, whereas Adam has one anti-spam filter, separated into three separate functions. (inbound, virus, anti-spam).
