Re: Port 25 blocking

[Matthew Keller <kellermg () POTSDAM EDU>]

We are blocking outgoing and incoming port 25 traffic to everything but

has been widely accepted. Our motivation was to prevent some of the spam
zombie viruses from using our systems to spam systems elsewhere on the
Internet. We try to be good netizens. :)
