Topic: Greylisting - domain vs. subdomain
I have a small problem. By what I see, greylisting is done on a per-subdomain basis. But that causes me some problems with a 3rd party hosting company which tries to send the same mail from different subdomains, so the greylist doesn't get validated.
For example, first try from gateway02.websitewelcome.com, second try from gateway31.websitewelcome.com and so on.
Can I enable greylisting validation on a per-domain basis, (for the entire domain gwebsitewelcome.com) instead of its subdomains?
