Why is mail sending occasional emails directly to trash?
This problem has been going on for a few months. There are no rules and there is no regularity with when this happens, But every day I must search my trash folder for all of my accounts to read mail that has cycled there unread. A few times this has occured with important mail which I almost missed! I have tried rebuilding mailboxes and removed almost all of my "rules" but it happens with a few emails every day.
