I have vpn users that can't access their e-mail at outside ISP via pop or imap clients. They can browse Internet and connect to smtp port but can't access pop or imap. In the logs of ISA I see following messages for IMAP Protocol:IMAP4 Action:Initiated connection Rule:RDP for remote desktop and after a while Protocol:IMAP4 Action:Closed connection Rule:RDP for remote desktop No denials , vpnclients are allowed to talk to outside servers. I am not sure what RDP for remote desktop rule means and where I can find it. It is not among the current ISA rules and not even listed in system default rules. Please help.
