It's not a real DKIM signature, and no email client parses it as far as I know, anything with X-
as you know is just extra metadata.
It's not a real DKIM signature
Last time I checked, it was. What else would it be? If it doesn't verify, that's another issue. If you have a real sample message, and a test case to prove it, I'm happy to look at it, and remove the X-Google-DKIM
matching, if it checks out.
and no email client parses it as far as I know
And that's an argument? Most email clients don't even check / verify DKIM signatures. Sorry, but that's just no standard I'm going to measure against.
Other than that it's not defined in an RFC, is it causing any issues, or why would you argue for it to be removed?
