telnet port 25 not available externally - 30.Oct.2007 2:46:01 AM

Hi,

we have a mail server that I can't reach by using telnet to port 25 from external locations. Mail is recieved and I can telnet from internal clients. Also, no hits are registered in the ISA server log when trying to telnet from outside.
If I try to telnet using port 110, then that is registered in the log.

Any ideas?

Something between the ISA Firewall and the telnet client must be blocking the connection.

HTH,
