I cannot seem to get the following rule working.
Requirement: I want to run a mail filter which says:
If the mail is in Account X, and has subject Y, was received less than 10 days ago, and has no MailTags, I want to move it to the Trash folder.
It seems to work partially - it moves some mail to trash and not some other.
Can anyone suggest assistance? The rule is located at the top of the rules list, so it should be applied first?
