Huh, once again someone mails the list with a hotmail-generated
mail error report and it doesn't say damn thing at all!
Why even send error reports to users when they don't mention _what_
the blasted problem is? (note, I'm ranting at hotmail, not you).
Users don't know to look up in RFC 1893 for extended status codes!
Anyway, the status code 4.4.2 is telling us it should have been
deferred. It seems like hotmail doesn't like to have any messages in
its queue :) Are you sure this isn't a deferral notice? I guess since
it says "Failure" in the Subject we have to assume it's not.
X.4.2 Bad connection
The outbound connection was established, but was otherwise
unable to complete the message transaction, either because
of time-out, or inadequate connection quality. This is
useful only as a persistent transient error.

Interesting, but I can only find one MX record in the DNS for vfive.com.
$ host -t mx vfive.com
vfive.com MX 10 bmw.vfive.com
Therefore, if that is the machine in New Jersey, that could be the
source of your delivery failures. Reasonable MTAs will defer the
message until it can be delivered (when the link comes back up,
presumably).
