Limit on number of rules in Mail

Greetings, erikfromvoorburg.

It appears you're having an issue with the Mail application on your iMac. You've created a number of rules, but they don't appear to be working like before. I'm happy to help.

Use rules to manage your inbox -- While there isn't a limit to the number of rules you create, the order in which they appear or rules used a mail server can affect how they're applied. Try rearranging the rules you've created, and check the mail server for rules that could be keeping them from being applied.

If you have multiple rules, they’re applied in the order in which they appear in the list of rules; drag a rule up or down to change the order.

Mail stops applying rules to a message when it encounters the Stop Evaluating Rules action, or when a message is transferred to another mailbox by rules used on a mail server or on a computer or device synced to your computer.

Let me know how that goes.

Take care!
