The latter! :-)

Seriously, I have some vague recollection of ~E and ~S, but no ideas
on how to use it. Maybe the author of this feature can chime in here
with specific examples?

I guess that's my job then :)

Okay. For one I have a few cron-jobs around which mail me various
information. (e.g. What today's meal in the canteen is) which is
short-lived and they get an Expires:-Header with an appropriate time.

Now i can Auto-Delete expired messages on entering my Mailbox, and thus
have the message only around if it matters.

I implemented Supercedes just 'while I was at it' I currently don't have
it in use right now. (would be kind of a security-hole if you allowed
other messages to be overridden(deleted). Maybe some check if it comes
from the same Person would help to solve this)

CU,
Sec
