Anti-spam and anti-virus suggestions
I would like to ask and get some feedback about the free anti-spam and anti-virus tools which integrate with the Java Messaging System from Sun. I would also like to express my concern with SpamAssassin since I suspect it uses too much system resources. But, anyway, if it blocks the spam with a higher percentage compared to other solution(s), then I would forget about how much resource it requires as long as it is in reasonable amounts.
Please send me your comments,
Thanks!

A rather common question. I give the same answers every time.
Messaging Server includes integration with spam scanners
SpamAssassin
Brightmail
and AV solutions
ClamAV
Sophos (integration done by Sophos)
Others can likely be integrated by one or more means.
Yes, SA uses resources. It does not have to be installed on the same box as your Messaging Server to use the integration. Many people find it very good.

Hi,
Following on from what Jay said, SpamAssassin can indeed use a lot of resources if badly managed. This includes using large numbers of rulesets especially if they add very little to the overall score, and simpler things such as not using a local DNS cache. SpamAssassin if tuned well and if your system has a reasonable amount of RAM (2GB or more) can work just fine.
For example I ran x86 dual-CPU systems (less powerful then say an x4200) which were able to comfortably Spam (SpamAssassin) and Virus (Sophos Anti-virus) process 100-150K emails/day.
At the end of the day you get what you pay for. I tried out the Sophos Anti-Spam/Virus solution (Puremessage which has its own messaging server channel from memory) and found it to be very competent & slightly more efficient then SpamAssassin. In this case the cost was the limiting factor.

Shane.
