I have installed a new iredmail server.  I use fetchmail to grab mail from an external host and deliver it to iredmail.

This works, but iredmail is bouncing messages with:
4.7.1 Recipient address rejected: Intentional policy rejection, please try again later

For now I have disabled greylisting, but this still sounds like a useful feature.  Is it possible to tell ireadmail's greylisting to ignore the IP test if messages arrive from a particular (internal) host? 

So if iredmail is 192.168.0.10 and my fetchmail is running from 192.168.0.11, I want iredmail to not consider the IP address as a factor if source is 192.168.0.11

I don't think whitelisting 192.168.0.11 is appropriate since even spam will arrive through that IP.

I assume other greylist features are worth keeping...so I don't want to totally disable greylisting.
