What is Greylisting


What is Greylisting?


Greylisting is a method of blocking significant amounts of spam at the mailserver level, but without resorting to heavyweight statistical analysis or other heuristical approaches.

Greylisting relies on the fact that most spam sources do not behave in the same way as legitimate mail systems. Although it is currently very effective by itself, it will perform best when it is used in conjunction with other forms of spam prevention such as profilter.
