I have an Exchange 2003 server that will receive emails and deliver to recipients, but nothing will go out of the SMTP server.
I have checked all of the SMTP settings and everything looks good, however I noticed I cannot telnet to port 25 from command line from the server.
I can from other workstations on the network.
I'm new to this client and not sure how everything is setup. It was working fine until today.
They are using an IPCOP box as their firewall and I can't see anything in there that could be causing the problem as well as there are no local software firewalls.
