As I understand it, spamdb works by using the fact that a large portion
of spam email is sent only once, so putting a delay by temporarily
rejecting incoming emails from unknown addresses can dump a lot of the
spam with that one rejection. Good email will always go through
eventually. Some spam too, of course.
So, normal spam - temp rejection, goes away.
Good email - temp rejection, keeps trying till successful and is
whitelisted.
Extra bad spam - temp rejection, keeps trying till successful and is
whitelisted.
Please correct me if I am wrong. Good emails and extra bad spam have
equal chance of getting through?
If this is true, would it be reasonable to significantly reduce
greylisting time after getting second try from a non-listed IP? (To get
new IP good emails faster)
Is this a silly idea or not?
