This is specifically to deal with the DMARC "from alignment" problem, which allows a domain to publish a restriction on who may use their domain in From. This restriction is respected by most receivers. Mailing list break both of the authentication protocols. This means that if the DMARC policy of the author's domain is "reject", receivers should refuse mail sent via mailing lists. So mailing lists substitute an address in their domain which they can authenticate to receivers. However, with respect to Wolfgang's posts, the official DMARC (RFC 7489) protocol is not involved here since gmx.net publishes a policy of "none", which means receivers should take no action merely on the basis of failure of From alignment. That said, the reason Google gave for refusing your email is based on From alignment. I suspect they have other reasons, my own organization (a university that has pretensions to world-class STEM research :-( ) marked your post as SPAM. Sorry, I can't tell you what the rationale is, the reason report is encoded. I myself don't see anything spammy about any of your posts. :-( > I wouldn't have a problem with the list maintainers setting up a > similiar procedure like in your case to deliver my emails to this > list - if it solves the problem: great! I don't think there is a problem with the lists. I suppose Fedora lists have thousands of subscribers. The weird thing is that you only received a few Delivery Status Notices (DSN). If something were broken in the lists you'd get thousands. I think that what is happening is that either there are a couple of broken receiver sites that sent DSNs to you rather than the list which should handle them, or (quite unlikely) Fedora has disabled the Mailman default of requesting that errors be sent to Mailman which knows how to parse several dozen styles of DSN, and if it can't sends to the list administrator (not to the author). The logic is that although the author sent the mail, the list chooses the recipients, and if the mail is bad (eg, spam) the list shouldn't send it at all, and if it's something idiosyncratic at the receiver (typically disk full or no such user), there's nothing the author of the post can do anyway (the list can and does disable delivery or even unsubscribe subscribers who produce lots of DSNs). > So yes: this email is explicitly meant to be also read the Fedora list > administrators. There are addresses specifically for that purpose. It is very frequently the case that list admins manage many lists they are not subscribed to. If you have specific requests for the list admins, use the -owner address. But think carefully about whether you need to do that. It's very likely they'll just tell you what I just told you, and there's nothing they can do. If you repeatedly get DSNs from the same domain, you can send them to the list owner, and they might unsubscribe those accounts. But that's up to them. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
