smtp server simulation using Python

[William Gill]

I have a (web) development computer w/o an SMTP server and want to test 
form generated e-mail using a dummy SMTP server that delivers the mail 
message to a file, or better yet, to a text editor instead of actually 
sending it.  Is it possible to extend the DebuggingServer class,and 
override the process_message() method to accomplish this?  If so, any 
suggestions are appreciated.
