i i myself have a great little windows 2000 small business server running, with exchange 2000 [sp3] running, all works great, dont really want to purchase windows 2003 sml biz server, or exchange 2003 server, as i dont have the funding, and my current setup works fine,,,with this exception.....
im running the trend micro client server messaging security suite, which i assume has been doing a good job of keeping virus's out, since i really havent gotton a virus via email ... but the anti-spam that comes included with it is pathetic, im constantly getting spam, especially alot of chinese alphabet spam, and 80%off, etc., etc...

any ideas, are there any free  exchange server anti-spam products or at least low cost solutions for this?
