we are receiving a few PGP-signed posts as a S/MIME attachment. Some final recipients check these, and as mailman3 does not munge them - the original mail is signed, not mailman3's final posts - those get rejected.
Besides Mark's suggestions, technically, PGP-signed and S/MIME are two different protocols. If you try to verify one with software expecting the other, it will fail. This seems unlikely (there would be reports of direct mail failing verification), but if Mark's suggestions don't help, you could verify that all the users are on the same page as to what signature protocols are being used.
