An open mail relay is pure gold to a spammer, and they scan for them
constantly. If they find enough of them, they can pour millions of spam
messages through what is, essentially, an untraceable network. Open relays
are a major link in the "Spam Road".
When an open mail e-mail relay is found at Penn, Information Security
will request that the owner or administrator close the relay or take the
server off the network until the relay has been closed. If the owner or
administrator cannot be located, or refuses to close the relay, Information
Security will request a port disconnection under the Disconnect Policy.
OK, I'm running an e-mail server - how can I find
out if I have an open relay?
