A quick google search reveals users complaining that Verizon DSL
does block port 25, except to the official Verizon SMTP relays.

The messages I saw spoke only of outbound email. I dunno if they also
block inbound port 25. You might call them and ask. Good luck with that.

I can't get DSL at home; live out in the sticks. But I do have the
new high speed Verizon broadband wireless Internet service. They don't
block port 25 on mine (yet).
