Milter-greylist

Hi,

I'm using milter-greylist 4.1.1

Up until the past week, the following rule:

        211.29.132.0/24    \ # optusnet.com.au (wierd retry pattern)

located in the:

list "broken mta" addr {   \

section worked fine.

Over the past week, it's stopped working with delays of emails from
optusnet.com.au from 30 hours or more. This is causing issues and I can't
figure out why that rule isn't working any more.

The received entry from the Optus MTA is:

Received: from mail03.syd.optusnet.com.au (mail03.syd.optusnet.com.au
[211.29.132.184])

Are there any additions I have to make to allow their emails through without
greylist checks?

I have restarted milter-greylist (not that I expected that to do anything) but
to no avail, the same long delays happen.

Any help or advice is very much appreciated.

Michael.
