There is no easy way. *but* it is possible to combat spam.

Some Linuxoids use draconian measures against spam.

such as:
1. drop all mails that include attachments.

2. drop all mails that include HTML/Javascript/ActiveX/Flash.

3. require all non-dropped mail to request image recognition.
 (the recepient's server replies with image-recognition question, and
the sender must approve that he is a human, otherwise mail get
dropped)

4. make white-list firewalls, only allowed users can send you. else is dropped.

NOTE: some Viruses, like "I love you" can come from known ppl,  so
rule #4 alone won't help you, but when all rules copmbined, and each
mail requires image-recognition, then spam stops TOTALLY.

With this you can achieve devastating effects, so only friends will be
able to mail you.
