Mac Mail Apply Rules. Create rules to filter your emails. The reason for this behaviour is that mail only appears to apply rules to new mail.
3) any rules you have set up will be displayed. The next day, more emails with the same return path appear, the rule does not delete them. Reply to/forward/redirect the messages automatically (handy when you’re going to be away for a while);
The rebuild process corrects any underlying issues with the program.
To set up rules, you first need to open up apple mail’s preference, which is done by selecting the mail menu and then “preferences” or using the command+, keyboard combination. Note that i’ve given it a mnemonic name. 2) in the window that pops open, click rules. Access the mail app rules.
