It's to do with using an in-core temp-file rather than a forked pipe for 
reading in the message when you explode out all the attachments. It will 
probably be easier to implement for Exim but the Postfix message 
structure is very different, externally and internally, which will make 
it a very interesting exercise... Take a look for "sendmail" in and you will find a big "if" statement, take a look at the 
code in there.

Well you asked! :-)
