I would suggest either an interface with a separate stand alone mail server, or an integrated C/Tcl module. Maybe a C/Tcl approach would allow integration of some available mail library. Dan Bernstein ( http://cr.yp.to/ ) has a library for parsing email headers, but it doesn't handle the entire message. Not fashionable, but C/C++ are still highly valued languages, of which there are a number of good examples in the AOLserver archives.
