> blocking our IP address for no reason In my 20+ years experience, there is never "no reason". The reason may not be clearly revealed, the rejection message may be lacking in useful information, and the reason may be wrong, but blocks are there for a reason, even if not discernible by the sender.

Never ascribe to malice (or in this case, perhaps, apathy) that which can be explained by stupidity (or, in this case, ignorance or unawareness). I've never, again, in my years of experience, run into a receiver who simply didn't care that their users were not receiving email that their users wanted. > I do suspect that John Von Essen's opinion has some merit.

There's no telling what email those same @att.net users are > not getting. People who are trusted do have that information. It's never going to be posted publicly on a website because a) spammers, b) malicious actors, c) people who just want to harass the people working for such entities, and d) people who are disgruntled or generally have a bone to pick, an ax to grind, or whom otherwise want to rant at them. Is it a perfect system? No, not by any means. But it's not quite as broken as you think (and trust me I feel your pain). You mentioned in your initial email that the issue is with these IP addresses: 23.239.97.150 5.101.141.35 AND that you "suspect that this is being blocked because these are new IPs that AT&T has never received mail from, so they block them by default." Receivers don't block email from new IPs by default; they block them when they notice something amiss with the email (be it improper authentication, spam complaints, or something else). What is the nature of the email which was being sent through those IP addresses? Instead of grumbling, if you can give us information, perhaps someone here can help you. Anne -- Anne P.
