Read the msg below from Cyberpromo. It is valid for ISPs to block at the
router level as well as the sendmail level as per Cyberpromo's mail. I
figured some people here may be interested in this.

And, now take a look at AGIS's abuse response. It's funny that AGIS and
Cyberpromo's responses are exactly the same thing, with "AGIS" instead of
"Cyberpromo". The rest of the mail contains the same suggestions...
AGIS also has another interesting way of handling spam complaints:

I've conveniently blocked cyberpromo's blocks. My upstream provider is
currently considering globally blocking cyberpromo. I am in the process
of determining the impact of blocking _4200_.

Ugh. That didn't come out right.
My upstream provider is currently considering establishment of
access-lists at their upstreams to block cyberpromo from reaching their
network as well as their customers'.
If I understand the way cyberpromo spam-central works, it would also
prevent your customers from using cyberpromo services because you would
not be able to send mail to their servers.

I'm becoming more and more convinced that it was not attacks AGIS was having
problem with. It was (and is) AGIS's own, er, inadequacy.

- END-USERs - A variety of e-mail and filtering software packages are
available on the Internet for end-users. For example, Eudora and procmail
offer sufficient protection from e-mail of your undesired Internet sites.
Or you can use the latest in filtering software, e-Filter, sold on
Cyber's own web page at... http://www.cyberpromo.com
Hold up. Just one second.
Cyberpromotions is selling software to block their own spam? That's like
the mob selling you protection insurace to protect you against the mob.
Gee, sounds like they are trying to get money from both ends.

I noticed this too... reminds me of Cincinatti Microwave, who made the
Escort and Passport Radar detectors (among others). Their other line of
business was making radar guns for the police... always seemed to me like
one hell of a business. Every new feature (or frequency) they'd put into
the police units meant they could sell a whole new round of detectors to
the public (and probably new detector-detectors to the Canadian police).
