I’ve created a new SpamSieve drone using Apple Mail (10.3) and macOS 10.12.5, with IMAP connections to all of my email accounts. It is catching spam and moving them to the spam folder on the drone, but when I get my mail from my iPhone or other computers, I am still seeing the spam.
My old SpamSieve drone was using Entourage 2008 and they were POP accounts, and the spam was being deleted from the server with no problem. I read that Outlook 2011 and 2016 had issues with SpamSieve using them this way, which is why I created a new drone using Apple Mail and only using IMAP. Is there something special I need to add to get the spam messages deleted from the server? It seems the rule Move Message to the Spam Folder only effects the local Apple Mail on the drone machine, and doesn’t delete the spam from the inbox up on the server.
