Good day,

We are having problems with a type of spamming technique. The culprit is
subscribing to phony POP accounts managed by one of our customers and is
spamming from his home. 

We are getting rather tired of this cat and mouse game and have narrowed
the origin down to a range of IP addresses.

Does anyone know of a way to filter out mail coming from a range of IP
addresses in our Border Gateway router (or in the customer's frontal
router)?

Otherwise, are there other ways to handle this ?

Thank you for your time.
