[afnog] how to block spam activity on my router cisco 2600

[JFL]

There are some who have opted for blackholing segments of the Internet 
which appear to be the sources of alot of spam. Not that this
actually works in the end. If your provider says there is spam from your 
ethernet interface, it is possible that one of your customers is infected
with a massmailer of sorts. Does all your mail go through a server 
before it hits your router? If so, do you have spam filters on the said 
server?

You will need to analyze the traffic and identify the abnormal or unexpected traffic or traffic patterns or get your uplink provider to be a more detailed as to what the are reffering to as 'spam' so that you are better equiped to address your problem.
