By shutting down those IPs, they effectively shut down their Intenet mail

All,
I've had good luck blocking access by denying all traffic to the IP
ranges of the login servers for those services. Currently I block all
traffic to:
AOL IM
152.163.0.0 /16 255.255.0.0
205.188.0.0 /16
64.12.0.0 /16
MSN Messenger
64.4.0.0/18 255.255.192.0
Yahoo
Excellent information. Does anyone else have tibits like this? I've seen
bits and pieces floating around on things to watch for regarding bad apps
and ports.
We had an issue with a 3rd party company(now a dot-bomb) who provided
firewalling and virus scanning. We got them to block real audio but
and deny everything else ( and don't call it Internet
access ).

I can't imagine the problem with Messenger apps. I feel that instant
communication can be handy at times. Sometimes I hate waiting for an e-mail
response, and a messenger service fits that niche nicely. And no, they
don't waste bandwidth. The messages are usually smaller than e-mail. And

Let me put something into perspective here. It was said earlier about why
give access then block it. Why indeed... the why is for BUSINESS reasons..
not day trading, not stock tickers, not chatting for hours(documented) with
friends at the expense of work, viruses coming in on Hotmail attachments

Employees will understand that monitoring needs to be done at times and
offenders be dealt
IM isn't anywhere near as bandwidth intensive as video, audio, etc. And I
can understand blocking video and streaming audio. But if you communicate
via e-mail or IM, they can both be for business purposes. I have seen plany
of non-business related e-mails in my time, just as I'm sure you all
