Perhaps you'd be better using a mail provider who support
filtering on their server?

Then isolation (by whatever criteria) of the mails you trust could
be done without even requiring use of an eyeball. They could be
moved to a separate folder and downloaded from there (or, if a
provider only supports download from a specific folder, those not
meeting filter criteria could be moved elsewhere).

If you still needed to use your manual scanning, at least that would
only need to be done on mails that the on-server filters hadn't
decided were ok?
