Mailing list & Gmail

[David Given]

Trying to preserve the original DKIM signature is unlikely to work ---
Mailman tends to regenerates the headers and body from parsed copies so the
details of the formatting can change, which breaks the signature. The only
thing which actually works here is to strip the DKIM signature (preferably
after checking it) and resigning the message when Mailman sends it. See for
example https://doc.coker.com.au/internet/dkim-and-mailing-lists/.
