My own suggestion is that we don't touch or try to interpret MIME. Parsing the message headers into a table is straightforward but once you get into recognizing MIME you're moving out of the protocol realm and into the message format realm - and you start having to worry about messages within messages, boundaries, corrupt structures, and other things that I think are not mod_smtpd's problem. I don't know if the other smtp project people share my opinion here.
