I've seen Sendmail delete Message-Ids it believes malformed, and generates
a new id. I did not look closely enough to determine what it thought invalid.

Real-life examples include:
Message-Id: News_03/11/2008 16:11:15_PR Newswire Brasil<[EMAIL PROTECTED]>
Message-ID: <42M0XSEC17ENNJN27.1103.753798 @lowbehold.com>
Message-ID: <2008-11-07 10:43:57 TheSystem@>
Message-ID: <[EMAIL PROTECTED] & Cloppenburg Website>
Message-Id: <[EMAIL PROTECTED] >
So the "address" token parser would have to be fairly "liberal".
