I do not see this. I have sent test messages that pass through two
MailScanner instances - one on the way out of my desktop and one on the
way in to my MX server - with Subject headers with trailing whitespace
and the headers are never duplicated and the whitespace isn't stripped.
In both MailScanner instances "Multiple Headers" is set to add.
I have tried one trailing space, two trailing spaces and a trailing tab.
In all cases the result is the same except for the specific whitespace
in the Subject: of the delivered message, one of which is attached.
If I'm not doing the correct test, please explain in more detail what
the issue is so I can understand how to test.
