greylisting

In Wikipedia it sais:

A mail transfer agent (MTA) using greylisting will "temporarily reject" any email from a sender it does not recognize. If the mail is legitimate the originating server will, after a delay, try again and, if sufficient time has elapsed, the email will be accepted.

But how can I find out how long these delays are on my server and on the receiving side?

My goal is to speed up email-traffic with partners using greylisting too and speed up the receiving of the first email someone sends to customers on my server.

I believe this is working, e.g. thunderbird (w/out password) reports that I am "not yet authorised to send mail for X from Y".
