Over at the Tor Project forum we’ve been mirroring mailing lists on the forum but the topics created as mirrors of the mailing list are often missing messages. The issue was troubleshooted and identified in another topic: Unexplained Email::Receiver::InvalidPost errors .
Would it be possible to find a solution so that mailing list messages from both known and unknown users are accepted? Otherwise, those mailing list mirror categories are quite broken, and it can become difficult to follow conversations because of the rejected messages.
