The list was silently dropping messages for 3 hours or so. It should be working now.
This started when I "fixed" the SMTP server's RCPT TO whitelist, which had previously been nonfunctional, to only allow mail to specific valid x...@agoranomic.org addresses. This was meant to block invalid incoming mail. Unfortunately, I didn't realize that this whitelist – unlike the more coarse-grained recipient-domain whitelist that was always in place – also applied to *outgoing* mail, such as copies of messages sent from the list to subscribers. So the list received messages, and added them to the archives, but, since list subscribers' email addresses are not @agoranomic.org, the SMTP server refused to deliver them to anyone. Since this was a permanent failure code, Mailman then dropped the messages on the floor rather than leaving them in a queue to be auto-redelivered. I tried redelivering them semi-manually based on the archives copy, but gave up: in part because it wasn't working, in part because I realized I didn't want to create any legal ambiguity regarding authorship. (G., that experimentation is why you just got a bounce notification or two from "test-list". Sorry about that.) Here are the affected messages. I suggest resending the PF ones, as they aren't valid public messages without being delivered to subscribers. https://mailman.agoranomic.org/cgi-bin/mailman/private/agora-business/2020-March/042431.html (BUS: Re: OFF: [Herald] A Huff that Slipped Through the Cracks) https://mailman.agoranomic.org/cgi-bin/mailman/private/agora-official/2020-March/013542.html (OFF: [Arbitor] Court Gazette) https://mailman.agoranomic.org/cgi-bin/mailman/private/agora-discussion/2020-March/057155.html (DIS: Mailing List woes?) Plus 3 more test messages on a-d I won't bother linking. Sorry for the inconvenience.
