The attached patch changed behavior in Sendmail that can modify the To header
that is received from the sender AFTER the message has been DKIM signed.

This behavior can cause issues in situations such as using Gmail to send to a
recipient using gmail where the To: address uses mixed case letters causing
DKIM after receipt to fail.

This patch from Claus Aßmann will be included in the next sendmail release and
was tested on Sendmail 8.14.5.

I believe this resolves the issue unless more samples are produced that show it
isn't a To: Case issue.

For those who don't want to patch/install their own sendmail, the nocanonify
feature has helped eliminate the issue in real-world environments as well but
is likely doing other things that may cause issues.

i.e. submit.mc and sendmail.mc including:

FEATURE(`nocanonify',`canonify_hosts')

Closing as invalid as likely a configuration/bug in MTA.

regards,
KAM
