It is possible, but you'll need squid + firewall (iptables in my case)
Rules i used in iptables:
iptables -A FORWARD -p tcp -m tcp --dport 5222 -j DROP
iptables -A FORWARD -p tcp -m tcp -d 72.14.217.189 -j DROP
Acl i'd blocked in squid:
acl gtalk url_regex -i .*talk.google.com .*chatenabled.mail.google.com
By some reason, some users still can connect using the executable
client. I'll try to debug this later.

I searched alot to find the solution but could not get any working
answer. How to block gtalk from google mail without blocking gmail
itself. We are able to do it for http://gmail.com but not successful
for https://gtalk.com.
May or may not be possible. With HTTPS all Squid has to decide with is
the domain name.
From the above you should be able to block CONNECT to .gtalk.com
If that does not work please show what you ave tried, etc.
