That most likely means that IMail sent the E-mail, but chesapeake.edu never
sent back the confirmation that the E-mail was delivered. It sounds like
they may have some serious connectivity problems.

Taking more than 1 minute to send a 1.5K E-mail indicates a connectivity
problem, as well.

That's a "Connection Reset" error. IMail received a connection from them,
but when it tried sending the greeting, their mail server had already
disconnected!

I doubt that. Their DNS looks pretty good at first glance. The
connections *are* being made and being made properly (you are connecting to
their mail server, and they are connecting to yours and your backup), so
that would rule out DNS in my opinion. However, there *is* a serious
connectivity issue somewhere between you and them, that is causing TCP/IP
disconnections and slow traffic.
