Is there any chance that SPF and DKIM records could be added to appear in the headers ?
The gubba-mint folks are getting extremely medieval about email security.
Um? Those already are added? Or what do you mean?

Wietse Venema gave this answer on the same question on the postfix mailinglist:
" The list server adds its own DKIM-Signature: on behalf of the domain postfix.org, AND it adds ARC headers and Authentication-Results: for the message as received before modiification and redistribution.
However it does NOT remove existing DKIM-Signature: headers that are no longer matching header and body content. "
I would guess the same applies for this list.
