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.
AOL got absorbed into Yahoo, which in turn got absorbed into Verizon, which in turn split off Yahoo mail to a holding company. So, yeah, it is anyone's guess what is happening off in Yahoo-mail land. *Yahoo* is known to greylist mailling list posts, either because Yahoo thinks they are spam or simply because it is getting too many messages from a given source. If the latter, configuring mailman to send fewer messages at a time might help.
Question: are there other people on your list with any of these addresses:
@yahoo.com @verizon.net @aol.com @netscape.com
FWIW, I have 99 yahoo.com members on my largest list (4300 total), 13 aol.com, and 3 verizon.net. I never have problems with these, not even gray listing (which is not terrible when it happens, since the post is eventually delivered). I do have SMTP_MAX_RCPTS set to 5, which may help. I also have dkim and spf set up properly.
That said, my problems with all Microsoft addresses (outlook, hotmail, live, ssn) were so bad that finally I just abolished them from the list. But this was not a problem specific to Mailman.
