Yesterday I make upgrade of ZCS, everything work great,webmail work faster but i notify problem with IM vs external server like Google talk.

I'm getting all users from my IM list off-line (before upgrade work great).

I'm getting this error message " 404 : Server not found " on my pidgin on external accounts... everybody see me off-line and i can't write anything to them.

Yesterday I use 5.0.13
Upgraded to 5.0.14

I'm trying to reboot server, but it won't help.

I can send message to users from gmail or other servers so i'm not banned, DNS working properly because email's coming so DNS resolve IP of gmail server properly.

I rely don't know what cause this problem, if someone have any idea please say
