[ih] FYI - spam filters in place

[Joe Touch]

Hi, all,

In response to the recent flurry of both spam and viruses, I have 
installed a spam filter on this list, similar to that which was 
developed for use on the end2end-interest at postel.org list recently.

FYI: this filter will occasionally flag posts as "held for approval", 
sometimes indicating a "suspicious header". This header is the one our 
spam filter inserts, not a comment on the headers of the mail posted.

Held mail is checked periodically (typically at least once daily), and 
forwarded if OK.
