In Mail setup rules for certain emails to go to certain saved messages boxes you have on you Mac. So in Mail's Preferences click on the Rules tab. There create a new rule 9calling it whatever you want" and say if a group of messages move to a certain saved email folder. You can setup several rules to move certain email to one work while moving other email to another box. This is what Rules are for in Mail.
In my first post I described that custom rules were the first solution I tried. Problem is, it seems that rules are not automatically applied to messages that have been opened on another computer. So if I receive three emails in one day, only read two of them at work, then sync my Mac with the server once I get home, my rule passes over the two opened messages and only copies the one which I haven't read. Is there a way to work around this without having to manually "Apply Rules" to each message?
Have you found your solution?
I am trying to find something to automate moving mail from inbox to folders "on my mac" for other users that refuse to shift emails out of their inbox. I have create a rule to do so for mail >30 days, however that requires manual keystrokes, "select all+ apply rules" it will not run automatically. Therefore I have to sneak around the office and do that for them when they are not looking.
Sorry to resurrect such an old thread, but why do you use such a stingy email provider?
If your email provider supports it, some don't, consider forwarding all emails to a different address (iCloud/GMail)
You don't need to notify senders since the old address continues to work
Replies to your emails will send as firstname.lastname@example.org
emails will sync seamlessly between devices
