Because "Reject" sends a mail back to the forged sender of
the spam (a bit no-no you will realise if you've ever been
on the receiving end of blow-back), and "Discard" means
legitimate senders don't realise they need to subscribe.
Unfortunately mailing list systems haven't caught up with
today's spam fighting and e-mail systems. :-( I'm sure exim
and mailman could be integrated more; haven't had the time
to work on that one yet.[1]
(Yeah, I know - osm talk is set up to reject - here is
another offer to give someone pointers on how to get
spamassassin installed for lists.osm. Maybe we need an IRC
"exim+spamassassin+clamav howto" session sometime!)
Cheers,

[1] SMTP-time reject if sender is not on mailing list they
are sending to and sender filter is set accordingly.
