Mac Mail rule fails to reliably send incoming mail to local mailbox
Mail Version 16.0 (3864.700.51.1.3) running on macOS Tahoe 26.7
I created a local mailbox named 123 and then created a rule that says
If any of the following conditions are met"
To contains [email protected]
Perform the following actions
Move message to mailbox 123
Set color of background to blue
Maybe one out of 10 times it works otherwise it doesn't move the incoming email but it always colors the background blue and leaves it in my main inbox.
If it does move it in my local mailbox, the background is also colored blue and a 1 appears to the right of the local mailbox name indicating its a new message I have not yet opened
Sometimes, it will flash a 1 to the right of the local mailbox followed immediately with the 1 disappearing and the incoming message no where to be found.
Something is wrong with the move part of the rule yet why does it work once in a while? If it matters, the email address its looking for is an iCloud alias (one of the three you get with each iCloud main address)
If I edit the rule, let say I change the background color from blue to red, when I click ok to save it a prompt asks if I want to apply the rule to messages in selected mailboxes and if I click Apply, it will move the email out of the inbox and into the local mailbox I created. Why can't it do that automatically when the email first arrives?
