We've implemented the GravityZone Email Security recently, and we're still working through some of the settings. We get a lot of notifications about emails ending up in the Global Quarantine, but they're delivering to some users, just not all, and we were fighting to try and find the source. It seems as though some users add the sender to the "Personal" Spam Deny list, but when we search for the email through the GravityZone portal, it doesn't populate. We DID find that if we select the specific mailbox, the block/"Deny Sender" option does show.
It's causing a bit of time to run through and try to uncover who blocked which address; does anyone know of any way to remove the option for users to add senders to this "Personal" Spam Deny list?
This is all I'd found on the Email security info page:
