	I have had mail repeated mail spams from a couple of sites,
noatably moneyworld.com and {sally,nancynet}.com. I think
moneyworld.com is out of "business", but {sally,nancy}net.com is very
active at the moment (see current discussions on
news.admin.net-abuse.email). {sally,nancy}net.com also seems to be
indulging in header rewriting, putting the blame on worldnet.att.net
(mostly); alternatively, they're telling their customers to post from
a "throwaway" account at worldnet.att.net. 

	This is enough of a nuisance to me (and the ~1k people that I
am acting postmaster for at eto.ericsson.se) that I will ask the
postmaster at ericsson.se to refuse connections from hosts in the
{sally,nancy}net.com domain, and add other domains to the blacklist as
they turn up.

	Ditto for me; unfortunately, I have now begun to get email
with my valid address :-(
