One of verizon's relays was misconfigured for about a week
(15th-21 Sept ie last week). It gave 421 replies when my
mailserver checked the sender's address by doing a RCPT TO
back to verizon's machine. Then one day someone must have
looked at the logs and it started working again.
Here's the log

Whadaya know. It's the same machine!
I don't know who to call, but I had a lot of trouble finding
someone at Verizon to help me setup my DSL modem about a
year ago so it would let packets straight through and my
router did the dhcp call. Everyone said that wasn't
technically possible. Eventually I found the right person,
who just read me the instructions - he said that verizon had
people reconfigure their modems all the time.
