Unfortunately this can be used to to send anonymous emails like "Naughty
Robot". There was a complaint here about Geocities a few weeks ago
concerning the "Naughty Robot"... There is no proof to say that this
originated at Geocities. It can be sent from anywhere in the World using
the Geocities's STMP server ...
I would say that, as an ISP, it would be in your best interests to prevent
anyone in the world from using your SMTP server to relay their messages. This
can be accomplished by teaching your SMTP server to reject messages it is not
supposed to handle. In order to accommodate your own customers, who presumably
will want to send mail from arbitrary domains, you have a separate machine
which does not accept connections from the Internet, but only from your
dialups. (It must, of course, be able to establish *outbound* connections to
the Internet....)
I believe that the benefit of not being the target of random spamming (that is,
avoiding having *your* servers used to transmit someone's huge mailing list) is
*well* worth the configuration effort!
