Amazon was objecting to this SMTP command:
RCPT TO:<m...@gmail.com> ORPT=rfc822;WPNY
That is, the problem was not with the recipient address, but with
the ORPT parameter for delivery status notifications.
The alternative would be to disable Postfix DSN support with:
/etc/postfix/main.cf:
smtp_discard_ehlo_keywords = dsn, silent_discard
so that it would send:
RCPT TO:<m...@gmail.com>
but that would be a blunt tool.
