Agreed, however the port numbers that the administrator allows to be
connected to will usually be severely restricted for security reasons.
Specifically, if you can use someone else's computer to connect to the
SMTP port on any computer in the world, you have got yourself an excellent
way of hiding where your spam is coming from. For that reason, a lot of
mail systems will refuse to receive mail from any system which is known as
an open proxy.
