Got a few mailing lists mirrored over at [Mailing Lists - Tor Project Forum](https://forum.torproject.org/c/mailing-lists/23) We recently noticed a few messages were not being mirrored from the Mailman3 mailing list to the forum. The email rejection logs show these emails having encountered a `Email::Receiver::InvalidPost` error. The error message logged is either of those two: > We’re sorry, but your email message to [“tor-relays@lists.torproject.org”] (titled [tor-relays] authority bandwidth measurements and latency) didn’t work. > > Reason: > > Access Denied > > If you can correct the problem, please try again. or: > We’re sorry, but your email message to [“tor-relays@lists.torproject.org”] (titled [tor-relays] Re: webtunnel bridges for the telegram distributor) didn’t work. > > Reason: > > Something has gone wrong. Perhaps this topic was closed or deleted while you were looking at it? > > If you can correct the problem, please try again. I can’t find anything wrong with these messages from looking at the headers, although in _some_ instances, the extracted body as logged only contains the mailing list footer, or in another instance, it’s a bunch of gibberish characters like there was some decoding glitch. I’ve tried to reproduce this issue using a test mailing list and test category but was unsuccessful. Any help debugging this would be appreciated. --- _[View the full topic](https://meta.discourse.org/t/unexplained-email-invalidpost-errors/377793)._
