[issue34881] unnecessary encoded-words usage breaks DKIM signatures

[Abhilash Raj]

Abhilash Raj <raj.abhilash1 at gmail.com> added the comment:

Just for reference DKIM-Signature header is defined in RFC 6376 and the BNF description for the header is mentioned here (https://tools.ietf.org/html/rfc6376#section-3.5).

It is a bit long so I am not copy-pasting it here.

I might take a stab at writing a value_parser for this, but after I can write some simple ones. This seems to be overly complicated with many (optional/required) fields
