I checked our log files, and did find some informarion.  Our SMTP server
(brownvm.brown.edu) received 16 pieces of mail from io.org between 7/6/95
at 23:41 and 7/795 at 03:15.  Here's a typical log entry:
 
07/07/95 00:20:34 TCP (3) Helo Domain: io.org 142.77.70.2
07/07/95 00:20:36 Received Note 12462468 via TCP (3) From <[log in to unmask]>
 
The mail was all addressed to LISTSERV, and contained hundreds of
subscription requests for addresses not at io.org.  There seems little
doubt the mail was forged in order to inundate those addresses with
mail.  Here are the addresses that were forged:
 
[log in to unmask]
[log in to unmask]
[log in to unmask]
[log in to unmask]
[log in to unmask]
[log in to unmask]
[log in to unmask]
[log in to unmask]
 
I'll keep the log files for a few days, in case someone wants more
detailed information.  I'm sending a copy of this mail to the site
contact at io.org, in case he can track down who did this.  If he
has logs, it shouldn't be too hard, since brownvm.brown.edu received
no other mail from io.org during that time period.
