Genius. Yes, the bodyhash_mismatch is in the DKIM stuff, and the message returned from MM3 has a footer attachment. Although I had modified the default to contain no content, it is still 129 bytes.
Second, the reason why I saw different behavior from my posts and my wife's was that she wasn't a member. When I made her a member and sent another post from her address, the bounce+ address showed up in the nonmember list identically. So all of this has something to do with how our email host handles the outgoing mail. TMD uses Mailgun as a mail handler that provides deliverability services. I have a ticket in to them, but haven't heard back. Mailgun appears to modify the return path to a bounce+ address that MM3 sees as a nonmember sender, and then the recipient's email handler sees it as equivalent to another address that might be in the envelope. The header of a message sent from st...@stevebrown.us to my radg.us address shows: spf=pass (fr-int-smtpin1.hostinger.io: domain of "bounce+906d23.99dcd9c-administrator=radg...@stevebrown.us" designates 143.55.232.17 as permitted sender) smtp.mailfrom="bounce+906d23.99dcd9c-administrator=radg...@stevebrown.us"; I think I have bothered you enough for something that does not seem to create any real problems or threaten to do so. So reply only if something here stimulates another thought. _______________________________________________ Mailman-users mailing list -- mailman-users@mailman3.org To unsubscribe send an email to mailman-users-le...@mailman3.org https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ Archived at: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/WCGBCLF6UU24KPHPJCSDFPZLVN3BFAKW/ This message sent to arch...@mail-archive.com
