I'm afraid I don't know any contact there, but someone else on CC might. > I am following up with our IT/mail team about DKIM and the correct > SMTP relay configuration for mailing lists.

FWIW, when I first investigated DMARC/DKIM/SPF in the context of mailing lists years ago, the following blog was a good explainer to refer people to: https://begriffs.com/posts/2018-09-18-dmarc-mailing-list.html TL;DR: if DMARC is used by a sender's domain, then the best situation is for the sender domain to have DMARC + DKIM enabled, AND for mailing lists to NOT modify the message text, nor any of the headers covered by DKIM. We believe qemu-devel does the latter part correctly, as we turned off modification of the Subject header, and stopped appending a footer to the message text. Unfortunately I don't know any way to trace the cause of your problems without info from the mail system logs on the mailing list server, which only the sysadmins have access to :-( With regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
