some civically irresponsible exits?

     The documentation that comes with tor rather strongly suggests that exit
servers should have exit policies rejecting the SMTP port (25).  The tor
sample torrc includes this rejection as well.  This rejection of exits to
port 25 would seem to be a Very Good Thing (tm) in light of the rapidly
growing waste of Internet bandwidth in the form of massmail.
     Nevertheless, I decided a few minutes ago to take a peek at reality by
playing with the "exitlist" python script in tor-0.2.0.9-alpha/contrib.  Using
one of the IP addresses for the system on which I get most of my email, I get:

     If any of the operators of tor exit servers at IP addresses in the
above list are subscribed to the or-talk list, I would be very interested
to know your reason(s) for providing exit service to massmailers.  It should
be noted that such practices tend to make system administrators who might
otherwise be sympathetic to tor users into avowed enemies of the tor network.
