No spamming here!   I have a program sends me files on a timer from my 
remote machine at home to where I work.    (Good for surfing at work - 
although no images) Now the place I am at during the day uses the 
Message Labs Virus Scanning Service so the email is definately being 
forwarded.  Anyway.  I have no problem sending to other servers it is 
only the @work one.   My guess is that it checks the headers and sees 
that it originated from my local machine, routed through my webserver , 
and assumes that it is spam and therefore blocks it.

Guess I will have to keep smackin' the code.
