Re: Greylisting

In some cases it may be being re-sent, but is coming through from a different IP address. If you have a facility to ignore the IP address, but can verify that it is from the same email address then Greylisting can still work. Not ideal I agree, because these things could be spoofed, but spammers are after the low-hanging fruit..
