Re: Blocking GIF Spam

[Robert Mozden <vexira_dude () YAHOO COM>]

I would think that using multiple things like
spamassassin, even a commercial product like VAMS,
would drop those down.  Both of those have learn
features where you can use the current database of
known spammers plus the auto-learn feature & custom
rulesets to whittle down those.

To comment on the botnets, yes, they are getting
worse.  Alot of them are incorporated into adware now.
 There was an article in April's Baseline about the
damage & cost that they inflict on IT departments.

There were several article that covered bots:

Bots: Seven Saftey Tips

If you would like information about vams, contact me
directly please.
