Thank you for that information. I tried what you said but am having problems, some of my inbox mail is gone, so I decided to get rid of all this. I selected the smart mailbox, went to Mailbox > delete snart mailbox, but all I got was another mailbox. I kept trying things and now I have 5 smart mailboxes and don't want any. This is over my head and I just want to close all them and never see them again.
My computer is acting crazy and I am wondering if it has something to do with all these constant incoming messages that never stop running. I don't need anything extra - like these smart mailboxes because I am not smart enough to run them.
Am I trying to delete the mailboxes wrong, or is there no way to get rid of them?
Thank you for helping me. A
