I sent this yesterday, but it never seems to have hit the list.

There are already a lot of ways to do this. Most email programs will let you set up filters which, if you use the right rules, will pre-emptively delete spam. On a grander scale, there is the MAPS Real-Time Blackhole List. (http://www.mail-abuse.org/rbl/) and the SpamHaus BlackList (http://www.spamhaus.org/sbl/) They keep a file of "known spammers" and anyone who runs a mailserver can query or download their list and simply block all mail from domains known to harbor spammers. Apparently (see http://groups.google.com/groups?q=sprint+sbl&hl=en&selm=linford-3CC566.10144007012002%40news.fu-berlin.de&rnum=4 and more generally http://groups.google.com/groups?q=sprint+sbl&hl=en&btnG=Google+Search ) some people using domains hosted by Sprint have been spamming and Sprint wouldn't do anything about it, so all Sprint servers got Blacklisted, and now Sprint Corporate email to customers bounces a lot of the time. Now Sprint is willing to do something about it. It's not a perfect system yet, but slowly it seems to be working. - Joel
