Generating multi-part emails

[Steven D'Aprano]

I wish to generate some test data for a program that deals with emails. I 
need something that can produce multi-part emails, including "broken" 
emails that violate email standards, especially when it comes to Unicode.

Does anyone know of something like this that already exists? It's not 
necessary for the package to actually send the emails, dumping them into 
an mbox is sufficient.
