Re: [FW-1] MSN and Yahoo messenger

[Ramesh Ragineni <rragineni@FW1-NOSPAMILOG.COM>]

Can you please give me more details? Here in our network we have allowed
yahoo,Aol,MSN messengers to users.
What is going to a big impact and how do we protect from this issues? how do
we restrict this traffic?

Thanks
Ramesh
