All emails mark as important

I have 2 emails add to my em client, only one of them is a problem, all emails that its import to the program is mark with importants, some on google said do a filter in gmail but nothing works.
it works for new incoming emails, but not the 2000 others in archive.

Try this setting in Menu > Accounts > IMAP tab for the Gmail account.

I guess you are using a old version, because mine doesnt have that feauture.

From your own screenshot:


oh yeah man, you are the man, thanks a lot, that works.
