Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
The DKIM2 spec defines base64 to allow FWS inside it. We need to strip whitespace before decoding any base64 encoded field. That includes mf=, rt= and s= in Dkim2-Signature and h= and r= in Message-Instance.
