This sounds reasonable.
Starting a server when the -l flag is given also sounds reasonable, 
although I can imagine you might not want to start one for security 
reasons (since there is no authentication, just IP address-based security).

What I think is more important than having a server start when given the 
-l flag is proper locking and synching of the database (closing and 
reopening it) by the filter.  If you have that, you can start multiple 
imapfilter processes, each with different flags to do different things 
and you don't have to worry about the database getting corrupt.

I have added some locking to my version of imapfilter so that I can do 
just this.  I haven't checked it in since it is a fairly significant 
change of the way things work (not so much in the amount of code 
changed), plus it is not complete yet (there are probably still places 
where the program exits without closing and unlocking the database).
