Ugg. BTW, outgoing.verizon.net is a horrible mail relay. It's
reliability is quite bad. It's not RFC compliant either - it won't pass
null sender mail (bounce messages) and the Verizon postmaster refuses to
fix it.

Not that this solves your problem, but you will probably need to find a
better mail relay at some point.

Stupid Verizon.
