You have a lot to learn about spam :-)
I don't mean that as an offensive remark, but simply stating that things
are not that simple.

When a spammer learns what you limit it (eg, they find you allow 1
message per minute), instead of giving up, you will probably find 10,000
machines connecting to you to send 1 message per minute.
Thus you are now allowing through 10,000 spams per minute.
