This is probably what happens. Mailman, the mailing list software 
linuxaudio.org uses, changes the content of all mails passing through. 
This causes the DKIM signature to become invalid and it seems like Gmail 
doesn't like that. There are some options to prevent this from happening 
with the current version of Mailman we're using but basically the only 
viable one would be the following:

          C. Replace From: address and forward replies

             Change the RFC5322.From address to a unique per-author 
address within the mailing list's domain.

                 user at example.com => unique-address at mailinglistdomain.com

             Add DKIM signature using the mailing list's domain
             If replies are sent to the unique address, forward them to 
the associated message author.

See: https://dmarc.org/wiki/FAQ#s_3

This would be quite an administrative burden, unless I could automate 
this in some way. If Mailman 3 can deal with this issue then that could 
be an option too. I'm open to any suggestions on this one. Contacting me 
off list about this issue is no problem, maybe even preferable, we want 
to talk Linux and audio, not mail issues right?
