Blocking Web Messengers

Armengolx7
Hello guys, i would like to know if any of you know the way(s) to block web messengers, i mean the onea that you can use from your mail client (such as yahoo, google, hotmail), that little application [:@] . The problem is that our CEO sent us the direction to block al IM, and thats the only problem i have right now [:O] . If any of you can help me with this issue, please help me! 

I´ll thank you 4EVER!

    I just reran my experiment.  In IM/P2P, I chose "Block completely" for 'Google Talk/Jabber'.  I fired up the live logs for 'Content Filter (HTTP)' and 'IM/P2P Classifier'.  I also went into my packet filter rules to select logging of all outbound traffic.  I still was able to establish a chat session between two different gmail accounts on two different computers, one "outside" the Astaro and the other in 'Internal (Network)'.  Nothing appeared in the log.  I did the same with Yahoo Chat from inside Yahoo mail.

    MBrophy, can you check your 'IM/P2P Classifier' log and confirm that it shows the blocking of gmail chat when done from inside gmail?  I don't use this, so I wonder what I need to do differently to configure the blocking of email chat with IM/P2P.

    Cheers - Bob
