Back on list

OK - I think I'm back on this list - it seems that (i) my ISP had
enabled spam checking (which may have been away all email from the list)
and (ii) enough messages to my address had bounced that mailman decided
to stop delivering list email to me.  So I turned off spam checking at
the ISP end, and re-enabled my address within mailman, and I just now
received the last of the test messages I sent.

We're getting some pretty huge levels of spam to the mailing list. 
Perhaps we need to restrict things so that only list subscribers can
post to the list?
