Hi community,

I am running Proxmox Mail Gateway on a virtual machine before a synology mail plus server.

I was extremely happy with the PMG and its skill level. So even as an enhanced private user I am considering to pay the license for such a good product in future.

However, there is the greylisting features which - in my eyes - needs urgently some tweaks and enhancements.

In last time I received emails from serious senders such as providers for different goods and services.

And unfortunately they are all on the greylist.

What's extremely weird is, that you cannot click a button on the tracking center and say "deliver". If you can do that for spam why not for less suspicious greylisted emails?
And what's weird as well is that despite the docs say they need to resend the mail, the resent mail is again and again on the greylist.

So you need to put them explicitly on the whitelist, and after you have done that you need to call the guys and ask them to resend it.

And then you hear, "oh it is extremely hard to reach you".

Have I missed something and there is a configuration magic?
 
If it does not work for you, you can simply turn it off (greylisting is a feature that can be enabled/disabled).

Ok, we can disable it, but I think Checole post is right, I had some very similar problem. I don't think simply "turn it off" is a good solution.
