Toot

Written by Goffi on 2024-10-29 at 09:02

My emails are often flagged as 'spam' for my recipients, notably on mailing lists. I've set everything up hopefully correctly (DKIM, DMARC, etc.) and I score 10/10 at https://www.mail-tester.com/ . I don't appear to be on any block list, and I own my domain (goffi.org) for over 20 years.

Any ideas what the problem might be?

For the record, I've got a detailed answer which may explain the trouble: https://mail.jabber.org/hyperkitty/list/standards@xmpp.org/message/PAVMJD45BQNN2VJ5IQMD5SC7N253LD4K/

So changing my DMARC policy from reject to none apparently did fix the issue. Thanks to all for support and replies.

@Goffi Is your IP address in a range that might have been used by a spammer? The mailing lists might not have a good setup for spam mitigation - there are some complicated things that you need to set up to properly forward mails DKIM/DMARC headers.

@praxeology I don't think so, and https://senderscore.org says that I'm the clear.

I have mostly problems with standard@xmpp.org, which is specially annoying as I'm an active XMPP developer, but it happens sometimes on other too (and it's actually hard to say if somebody has seen my emails or not if there is no answer).

@Goffi This is it. If folks are sending to your list from mailing-list-incompatible domains (ones that use DMARC to say lists aren't allowed to forward them to subscribers) then your only options are to exclude those senders or rewrite their mails to change to a fake sender. Forwarding as-is won't get thru to anyone enforcing DMARC, but will get you marked as spammy (for disregarding DMARC and sending as an unauthorized user of the sending address).

@dalias I've loosened my DMARC policy from 'reject' to 'none'. I hope this will fix my issues.

@Goffi Oh, I thought you were the one running the lists. If you're sending to lists, yes, you're in a position to fix this just by disabling DMARC for your domain.

@Goffi capitalism and monopolies. Microsoft and Google just don't care about small email senders. Sadly. https://berthub.eu/articles/posts/who-controls-the-internet/

@Goffi Some mailing-lists breaks DMARC and DKIM.

@breizh yes that's probably the problem, see the link the detailed answer I've posted above (https://mail.jabber.org/hyperkitty/list/standards@xmpp.org/message/PAVMJD45BQNN2VJ5IQMD5SC7N253LD4K/).

@Goffi Could it be that anything not from Google, Microsoft or perhaps Apple domains automatically get flagged as spam?

@ball not automatically, but it's harder if you're not coming from a big email server. The problem in my case is probably due to the mailing list breaking the signatures (due to changing the body to add footer with unsubscription links), see https://mail.jabber.org/hyperkitty/list/standards@xmpp.org/message/PAVMJD45BQNN2VJ5IQMD5SC7N253LD4K/ .

@Goffi

Probably has to do with:

• https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/handlers/docs/dmarc-mitigations.html
