[Mimedefang] Using a db for subject lines to block

That should be fixable.  Why can't you do something like:

ifdef(`DATABASE_MAP_TYPE', `', `define(`DATABASE_MAP_TYPE', `hash')')
Koksubj ifelse(defn(`_ARG_'), `',
  `DATABASE_MAP_TYPE -a<OK> /etc/mail/whatever',
  `_ARG_')

I'm pretty sure that's the key lines that define a db hash that is 
updateable on the fly.

No argument there but I typically write emails like:
$@ $1 $@ $&t $<?> $: R$* +
In fact, if I ever snap, I will be known as the "Sendmail Killer" and I'll 
write all my letters to newspappers with this syntax.  I probably should 
give some props to DFS so maybe I'll give hints to the police to filter the 
emails with MIMEDefang.  Perhaps we can get DJB to play a protagonist and 
solve the riddles using qMail.
