[Mimedefang] List of nasty headers to strip?

[Andy Lyttle]

Hey all,

I've noticed that MIMEDefang will delete or change certain headers,  
such as Content-Transfer-Encoding.  Is there a list somewhere of  
problematic headers that will be stripped out automatically?  What's  
the best way to get MIMEDefang to always strip specific headers?  In  
particular, I need to make sure X-UID gets stripped, and it wouldn't  
surprise me if there are other nasties I should be watching out for.   
Recommendations?
