With very few exceptions, no one with a verizon email account can send email to trinityarlington.org or hardts.net. Any sender gets a daily email from verizon saying that delivery failed (6-12 times) and verizon will try again for 3 days. The error is always "initial status response expected". This is probably a handshake error between verizon and trinityarlington.org or hardts.net.
I tried talking to a support agent who kept trying to blame my email client (a ridiculous approach since the rejection letter implies there is nothing for me to receive). I have to tell my 250+ member church that verizon email accounts cannot send mail to our pastor, choir director, etc. And Verizon doesn't care. (Interesting fact: one email did reach me - the sender was using a BlackBerry so probably using a different email server).
I expected Verizon to research the problem and tell me that they could solve the problem or tell me that the host of trinityarlington.org was not following standard protocol and should upgrade their server. I am very disappointed.
If anyone has solved a similar problem - please let me know...
