Make sure the internal SMTP server is a secureNAT client to the ISA.

From an external site, 'telnet hostname smtp' gives me the error 'No route to host'. However, I can ping 'hostname' (the ISA server responds) with no problem. From an internal host, I can 'telnet internalhostname smtp' and connect fine Any hints out there? I'm tearing my hair out.
