[Greylist-users] Re: greylist

[Evan Harris]

Thank you for the patch.  I've integrated something similar into the source,
and will be updating the online version shortly.

As to the other idea of whitelisting IP addresses automatically, that is
probably a bad idea, because it is too easy for spammers to take advantage
of.

All a spammer has to do is send one message through the system, and once it
gets through, they can then send as many mail messages to any users on that
system as they want.
