[exim] Greylisting - Chnging IPs

Hi all,

I have recently implimented greylist on some of our servers, and am seeing a
few domain, that return multiple IP address. How is that handled.

I am also seeing a few (like telus.net) that resend mail from a different
mail server than the original. How do we handle that?

I have my accept time set to 2 minutes. Does anyone think thats too long?
