Re: SA DKIM related bug 6462 - Possibly Gmail, Sendmail and/or Thunderbird related?

My manual injection test concurs with your very clever mail queue check
though your check more definitively rules out procmail as well.
This is a big issue and major barrier to DKIM validation because if the
rcpt to: data is in a different case than the To: Header than I believe
DKIM is going to fail when sendmail uses to rcpt to: data to rewrite the
To: header.
Any ideas of who is it fault to work on fixing this very large issue?
Is DKIM supposed to be using case sensitive information from the To: Header?
Is Sendmail allowed to rewrite the To header?
Are mail clients supposed to use a different case for To: headers than
for rcpt to: data?
If you are using SA 3.3.2, the T_DKIM_INVALID test will flag DKIM_SIGNED
emails that don't have DKIM_VALID hits. From spot-checking my tiny
server, I've got at least 200 candidates in 12 hours that look to show
this is a broad, real-world issue.
