Working Group Chairs,

Some years ago all IETF mailing lists were configured with a default spam filter.  A recent survey of IETF mailing lists shows that 40% have no spam filters in place.  In order to re-establish a baseline configuration the Secretariat will be applying the spam filter to all lists that do not have one in place.  This default filter is:

	Spam Filter Regexp:  X\-Spam\-Level: \*{5,}
	Action:  Discard

List managers can adjust filters as they wish by going to the mailing list administration page -> Privacy Options -> Spam Filters.  Going forward, new lists will be created with this default filter.

Thanks,
  Russ
