The Exchange 2000 server is behind a NAT and I have looked into the

Any ideas or comments

Connecting To mail.intas.be...Could not open connection

Ran into this the other day with relaying. If your behind a firewall and
it
is configured to block telnet sessions then that is why. Try telneting
from
within your network.

Sorry, that is not correct. A telnet to port 25 is exactly what SMTP
is.

Can you allow internal IP addresses to relay? Or, you can set up for smtp
auth for the Macs... I am not sure about the commands that you would have
to do for the web based app thingy you have though ;)

I believe this is an issue that would require those users to use
authenticated SMTP... do they not have the option to authenticate to the
smtp server (in this case your exchange server) in their client?

Telnet to port 25 of the machine
Search the internet for open relay exchange 5.5, there is a good article in

Here's a telnet example:
