How does that get executed.  I take it I can't do it via cron.  Does
it run at deliver time for each mail message?  Is it doable in version
1.1.11 (that's what's in my version of Ubuntu)?  Do you know which
Ubuntu 9.10 package to install (we're stuck on 9.10 until the new
server arrives around February).
