Have you tried the SMTP diag tool from MS??

This may give you an idea.

This looks like a fireall is curpting your communications between the two SMTP servers. Do you have a firewall. There is defintely a curruption of packets.

underscores are invalid in hostnames, so the external mailserver refuses connections from your host as long as you use "iopc_relay.iopcfund.org" for it.

Best is to fix your hostname to not contain invalid characters (_) in it, and the problem will go away.
