It seems that Sourceforge silently drops DKIM enforced mail like jgarzik's. LF seems to pass along their mail but mangles the header/body and makes DKIM verification fail, which causes gmail to toss it into the spam folder. I think this behavior is slightly worse than Sourceforge because it makes the poster think their message was successfully sent (it is in the archive), but many subscribers never see it due to the spam binning. I don't see any good solution to this except an auto-reject for DKIM enforced domain postings. Yes this is rather terrible, but the instant rejection is vastly better than Sourceforge silently dropping the post or LF getting stuck in spam filters. We should also auto-reject any other reason for mail getting stuck in the moderation queue like including non-subscribers. I considered auto-rejecting spam too, but that could go horribly wrong as a false From address could make the Mailman server into a spammer itself. We may have no choice but to silently drop spam for that reason. Warren --e89a8ffbaba7f81a6a0518dc216d Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
