Last change wins.  I think most of the by email changes be gated by ack 
messages anyhow, so that I can't surreptitiously upset you by spoofing 
an envelope and asking for extra header munging.

In general this is because there's a lot of code that just doesn't 
exist yet.

Also I've not yet put any code in the Request plugin (the semi-clever 
thing that handles foo-request@ emails), which will be doing a lot of 
this stuff.

You're forgetting per-user configuration[0], who if aren't using web 
sure as hell won't be using nacho.
