There are very few RFCs that are directly related to spam, but a
lot of sites offer advice.


Is one of your customers sending or relaying spam?

Then you should make them stop by telling them what marketing
techniques are acceptable, by helping them to configure their mail
systems correctly or by disconnecting them.


If instead someone is sending spam into your network from outside,
you should look at the messages or the traffic to find where the
spam is coming from. Then try to persuade the spammer's service
provider to help you (both those tasks can be difficult).
You may also need to block some incoming traffic.

The IMC pages at
http://www.imc.org/imc-spam/
refer to three RFCs.

http://mail-abuse.org/
is the MAPS front page.

http://www.abuse.net/
offers some different services.


Tell me a bit more about what your problem is, either on or off
the list.
