How do you deal with Spam?

[Randi]

Note for british members - NOT THAT SPAM!!!

I suppose we all get more and more spam, and it's very annoying!! Only a few weeks ago, I started copying the spammers IP addresses and wrote to our provider to see if they can do something about it. I know there are blacklists, but as the spammers keep changing addresses, it's useless!
I've tried to block them on our mailserver, it doesn't work either.

I like this article about spamming!
