Hi
I am a Hosting Reseller and for over 3 months my Hosting provider has been having an issue with emailing to people that have Greylisting activated on their Servers.
They have been trying different configs without any resolution.
The email gets defer (-44) then gets removed from the queue without retrying so my clients are complaining emails are not getting sent works fine if they email 5mins later but the initial email they have no way to know that it was never sent, this is the log
