Verizon's SMTP blocking is NOT an anti-spam measure, as the company claims, but a way to force their users to switch domain hosts ...
I had a somewhat heated exchange with their abuse desk about this very topic. It turns out that it actually is an anti-spam measure, albeit one that's almost completely ineffective and has the not altogether undesired side-effect of pushing people to sign up for their hosting service. VZ is still in the process of merging the former GTE and Bellatlantic ISPs. They know that the correct thing to do is to allow their customers to send mail with any return address they want, but and require mail from outside to be addressed to one of their domains. But their network is a mess and they're technically unable to tell which IP addresses are customers and which ones aren't. (This isn't quite as trivial as it sounds, since there are shared dialup pools that are sometimes used by VZ customers and sometimes by others, but it's a problem that other large ISPs solved years ago.) So they slapped on the best band-aid they could devise in five minutes, which was to force the domain on outgoing mail to be one of theirs. They tell me that when the mess is cleaned up, they should change the rules to be reasonable, but I have no idea how long that'll take. -- John R.
