How to determine which messages are being deined
I was wondering if there is a way to see which messages are being denied by our inbound server policies? We have not set the deny option in the config of any incoming mail and have set it to quarantine meduim and high threat spam messages. I cannot find a report on which addresses are being denied and also the users do not always receive notifications to alert them a mail was denied. Ultimately I would like to find out so I can make sure the right emails get through.
Any advice is appreciated.
