Hi Leonardo,

One question I have is what deliver actually does over and above just  
dropping the message in the right maildir.  Depending on that answer,  
what I'd try to do would be to recreate that functionality in Python,  
either by implementing it in straight Python or by wrapping enough of  
the deliver code in a Python extension module.  The idea being, the  
external machine's Postfix connects to the internal machine's Python- 
based LMTP server, and the latter does whatever it is to make Dovecot  
happy then puts the file in the maildir.  That way you don't have to  
run a full blown Postfix on the internal machine.

Other than supporting the Dovecot-specific extra magic that deliver  
performs, I'd say the rest of the code is 99% there.
