AT&T has now started blocking the IP address of the multiple auto-forwarding email addresses I set up to get around them blocking the IP address of my GNU Mailman list. So even that labor-intensive strategy won't work. You'd have to be sending from multiple different IP addresses.
Dream Host to their credit jumped right on this and also tried to resolve the problem with AT&T. No responses from AT&T. This includes sbcglobal.net, att.net, flash.net, bellsouth.net, optonline.net, worldnet.att, and ameritech.net .
37 list members at risk unless they change their email addresses. We started 20+ years ago with a different list program and hosting provider, so we have lots of legacy members suddenly getting cut off.

I should mention that for the free att.net account I set up (managed by Yahoo) that as the end user I received *NO* notifications of any sort. List emails were not even sent to a Spam folder!

I can second this. I believe AT&T has been blocking for months or years, but with Dream Host rebuilding their discussion list servers in July, it gave AT&T a new opportunity to reblock us anew and a new opportunity for list administrators of GNU Mailman lists hosted at Dream Host to notice.
I have 36 list users all blocked from AT&T managed accounts at the following domains: sbcglobal.net, att.net, flash.net, bellsouth.net, optonline.net, worldnet.att, and ameritech.net
Almost all of these flow through email servers at the prodigy.net domain, but please notice that this also includes att.net domains managed for AT&T by Yahoo (no Prodigy servers involved).
AT&T has ignored my (very polite) screams for months, and this week Dream Host support reported back that AT&T is no longer answering their inquiries. According to Dream Host, AT&T recently blocked 8 additional IP blocks (or just IP addresses?). For one of them, AT&T responded saying it was in error (and unblocking it) and saying something to the effect that they block any IP block sending too many email. For the other 7, crickets.
I do observe that my IP block is on the UCEPROTECTL3 blacklist, although I don't know that AT&T is using it. UCEPROTECTL3 would, however, be happy to "express delist" my particular IP address as its doing nothing wrong for the low, low price of only $25 per month. Jerks!
I have (temporarily?) fixed this by creating nine or so auto-forward email addresses that auto-forward to 5 AT&T accounts each. (Dream Host users: you can't just create one auto-forward address to send to everyone because Dream Host themselves limit email addresses to about 30 emails sent per hour. Also -- with Dream Host auto-forward only email addresses you won't see bounce traffic when AT&T starts blocking again.)
What a mess.

- They are rejecting our list mail with a reject notice, but let individual messages through. I have different outgoing server for mailman. My servers are hosted at Dreamhost, who generally has very helpful support, but in the past 3 weeks they are not able to convince sbcglobal & att to let our mail through because they banned our IP block.
I did set Mailman to give me notice for each bounce notification so I could see what was going on, and when the bounce counters were incremented. That helped me be more aware.
Immensely frustrating, as almost half of our list members have sbcglobal or ATT & are losing contact with our group.

Hi,
Yesterday I received a report from an AOL user that she's not receiving traffic from one of my lists. The problem here is that my server logs show outgoing mail being accepted by AOL's incoming mail servers, and of course after that it's anyone's guess what happens to them. She says she's checked her junkmail folder and the messages aren't there. Does anyone have any thoughts on this? Is AOL known to silently discard mail they think is spam for some reason? I replied to her message from the same server and she did receive that reply, so they haven't outright blocked my IP or something. Even if I could contact someone who knows what they're doing at AOL, there are no error logs for me to show.
