Milter-greylist

Hi,

I've whitelisted the following domain:

au.pwc.com

with the following in the greylist.conf file:

acl whitelist domain au.pwc.com

as they're valid senders to one of my clients.

However greylisting still delays emails coming from them and doesn't whitelist
them. So I'm wondering, does the milter-greylist whitelist use the "from"
domain or the domain of the smtp server?

Their smtp server is:

aapmpx02.pwc.com [203.11.226.6]

So should my whitelist entry actually read:

acl whitelist domain aapmpx02.pwc.com

?

Thanks.

Michael.
