can't telnet a server outside my network

Hi, I have an external email server, i have a rule in my ASA to allow all
inbound traffic access the server ip on the ports used. from all PCs in my
network and servers and telnet it except from my intranet server.

I am trying to use it as smtp for an asp .net, when I run the application in
my computer through visual studio, it sends emails, but when i publish the
web application to the intranet server can't send emails, I get the error
"connection refused"

I also have an ISA server. can someone advice me please on this matter.

Do you have SMTP outbound access right for your Intranet server ?
What happens when you try to connect your External Mail server over SMTP
port from Intranet server ?
What happens when you run a command like nslookup -q-mx somedomain.com on
your Intranet server, does it resolve names and mx records?

Hi Osman, thanks for your reply:

A: How do I verify this?

> port from Intranet server ?

A: No connection could be made because the target machine actively refused it

What happens when you run a command like nslookup -q-mx somedomain.com on
> your Intranet server, does it resolve names and mx records?
A:Non-authoritative answer:
Name: yahoo.com
Addresses: 216.109.112.135, 66.94.234.13

Osman, the problem was solved. It was a restriction in the firewall, thanks
for your help.
