One needs specific sets for personal email or when driving
a mailing-list, at least for the oversigning (that i call
sealing); i document the sealing built-in list (for my one) like

         Remarks: In order not to break mailing-list posts (handled by
         software which does not recognize message signatures) the built-
         in defaults exclude ‘Reply-To’ and all the mailing-list related
         fields of RFC 2369.  In order to ease DKIM signing for mailing-
         lists as such sealing provides another built-in default, ad‐
         dressable via plus sign ‘+’.

Only to mention it.
