We can't seem to send emails to *@verizon.net addresses. The error we get after a while is #550 4.4.7 QUEUE.Expired; message expired ##. Messages sent to that domain just queue for a while then error out. We can send to all other domains. I checked and our mail server isn't on any blacklists I can find. I don't think it would do me any good to contact Verizon or even how I'd get a hold of anyone in their email department. is there anything I can do.
