> my request for comments on people using both IMGate and SPAMASSASIN. I tried it, and had to remove it.
SA, in my opinion: Is designed around being run on the mail server where the mail delivery occurs. It is intended to be used as a tagging tool so that people can filter to sort and/or delete based off the SA rating. This makes it a poor choice to run on a gateway in an ISP situation. SA was killing all religious newsletters that went in or out from our service. These newsletters were actually scoring higher than porn spam due to their use of HTML tags, imbedded pictures, poorly done signatures, etc. Since we host something like 5 churches, and a prison ministry, we have a lot of religious news letters going in and out. No matter what I did, these news letters out scored the porn. That was only the most major side effect. There were several other false positives. I think this is largely to a combination of some spammers getting smarter, and sending better messages, backed up by many users and news letters being more sloppy. This causes the scoring gap to be very narrow. So while SA was very powerful at killing junk, the collateral damage was far too high for us to use it here. --Eric
