To get or prevent from getting?
If you are a lover of spam, just put an unsecured Win2k box directly
connected to the internet with IIS and SMTP. I'm sure someone will ensure
that your love affair continues.
For prevention, I have found that a combination of solutions work better
eliminate a good portion of spam. The combination is Bayesian, RBLs,
recipient filtering, and sender/subject filtering. I haven't found a
single methodology that is effective. So the big question is, where is this
solution supposed to fit in? (eg. Exchange, stand-alone hardware device,
Win2k's SMTP service that is part of IIS, .etc)

ps - don't forget to check with your antivirus companies since they may have
av solutions that include some measure of antispam protection. Many will
include a combination of methods listed above.
