Hmmm, that looks like an error message from your email server. My
guess is they have instituted some sort of rule as an anti-spam
measure, and you're falling afoul of it. It's not entirely clear from
their message whether it's your return address that's upsetting them,
or whether it's your computer's IP address, but since we can only
fiddle with the former, let's assume it's that.

Really? Huh. So, assuming you're succesfully authenticating, that
means it's actually an anti-VIRAL measure that you're triggering. Not
that that's important, I suppose, just thinking aloud here.

That shouldn't matter.

My guess is that the problem is your return address. For historical
reasons, if you don't specify one, mutt guesses your return address
based on your local hostname and your local username. Unless you run
your own mail server, though, mutt's guess is almost certainly
incorrect. You probably just need to specify your *actual* verizon
email address, like so:
set from=russurquha...@verizon.net
set use_from=yes # this is the default value
In your case, what mutt is probably guessing is:
russurquha...@russ-urquharts-computer-2.local, which of course isn't
an email address that Verizon has any interest in allowing. You could
force mutt to guess the correct address by setting your hostname to be
verizon.net, but that wouldn't be a good idea for obvious reasons. :)
