My domain "jcea.es" has a strict DMARC configuration and this mailing list is not mangling email headers enough to satisfy any email server actually verifying SPF/DKIM.

As a result, I get quite a few DMARC failure reports each time I send an email here and those mail servers just drop the message. Beside this mailing list getting a bad spam score (and that is risky by itself, trying to get out of gmails or hotmail black lists is not fun at all), I guess I am not the only contributor with that issue.

Your mailman software is old, but it has the appropriate configuration flags, as documented in <https://wiki.list.org/DEV/DMARC>.
