I have an Exchange 2000 box sat behind my ISA server. It can receive
mail ok but I cannot get it to send. (Cannot connect to external smart
host)
 
I have followed the new SMTP tutorial but am getting no joy !
 
Basically I am trying to test by telneting to port 25 on my ISP?s smart
host. I can resolve the smart hosts name FQDN via DNS ok, but the telnet
connection fails.
 
I can telnet ok from behind the ISA server on a machine with the
firewall client installed, and it works ok on the ISA server itself.
 
I created a outbound SMTP protocol rule, and one for DNS, both apply to
any request.
I have disabled the SMTP service on the ISA server.
II have published the Mail server.
 
According to the tutorial, that should be it.
 
It still don?t work and I don?t know what to do !
