Jules,

perhaps MS should not even start if that is the case ?

It's probably the MTA (or MailScanner) attempting to render the message 
in a form correct for the next mail handling program it passes through. 
There should always be a blank line after the last header. But I don't 
guarantee what MailScanner will do if the headers end on an incomplete 
line, as it never happens in real mail that hasn't been screwed by 
something (in your case, the space in %org-name%).

The point about spaces in %org-name% is very clearly documented in the 
MailScanner.conf file.

If you break that rule I make no guarantees what may happen to your mail.

I will add some more code to check for that and flag it very boldly in 
the logs, and ensure that MailScanner --debug and MailScanner --lint 
check for it too.

Jules
