Runs on top of Sendmail or Postfix, supports text blocking, filename blocking, filetype blocking, integrates with SpamAssassin for spam blocking, integrates with just about any linux AV program for virus blocking (We use BitDefender, which is free for even commercial use) and is open source. It also does disclaimers appended to emails, if your corporate environment requires that sort of thing.

There's also a commercial version called XaMime, which includes things like web-based administration, etc.

I use Sybari Anti-gen v7.5 with Anti_Spam module, and love it. the virus filtering is the best, and the RBL/Whitelist support is great, and once you start working with interface, it it easy to learn and manage. I average over 10,000 spam blocks a day, and have not had one virus/worm get through Sybari because of the file filtering settings. My only complaint is the filtering list, which was to 'PC' and had to be cleaned up, it was block mail from valid users based upon key words or parts of words that never should have been blocked like 'kraut' or 'coon'. I have evaluated others, but nothing has even come close to matching my experience with this product.

I started as IT manager here at my company 2 months ago and they think I'm a god, much due to one particular product - Symantec Mail Security. They were inundated with spam - some users getting as many as 100 a day. One of the first decisions I made was to implement Symantec antivirus, because we were nearly at the end of our McAffee licence anyway, didn't have nearly enough licenses, and because I prefer the Symantec product in general. It shipped with SMS 4.0, and it sort of worked, but was a bear to administer - the worst thing being the inability to quarantine gray area spam messages to watch for false positives. I called Symantec, and they told me to download the new version 4.5, and what a great product it is. I'm using the heuistic spam filtering, set up to dump anything with a score above 3, and quarantine scores 1-3 in an alternate email account I set up for that purpose. Even without using a subscription blacklist - which you CAN do with this product, it's blocking about 98% of the spam that WAS getting to my users' mail boxes. I spoke with one of them this morning, and he said that he had 6 of them from the weekend. A typical Monday morning for him would have had him deleting over 200 spam messages. We were about to take the plunge to an outside service to the tune of $250 per month for filtering, and now we can keep it in house for the cost of software we already own the license for anyway. Good deal.

We reviewed a number of vendors and I have to recommend TrendMicro's ScanMail and eContent Manager. eContent manager allows you to manage your own filtering without being totally dependent on an outside source to determine what is or is not spam.

I have evaluated about every SPAM product for Exchange that is on the market. Sunbelt Software's IHateSpam Server edition is by far the best. We got a 25 user license for less that 500 dollars with 1 years support. Their latest version (1.5 I beleive) catches 99% of all spam coming into our network. I have evaluated other products with the same success rate, but they cost in the 7,000+ range. You cannot beat this product for the price and performance.


It is what it is!!

We tried Trend's Scanmail for a little while, but it turned out to be a fairly poor product. It actually ran on the same servers that stored the mailboxes, so we had to buy copies for each mailbox server, and then applying it's filtering ate up CPU scycles across the board.

We eventually settled on XWall because the filtering was done at the SMTP gateway servers. That way we only had to buy 4 copies instead of the 100 or so that we would have had to purchase from anyone else. And while there was some performance degradation on the SMTP gateway servers, since these boxes were dedicated to inbound/outbound SMTP traffic the slowdown wasn't visible to end users. I firmly believe that anything that doesn't do the filtering at the gateway is going to be a pig of a product.
