I'm giving ANOTHER five stars -- and no, I don't have any connection whatsoever with the software author -- to counteract the one star by gerardrj, who gave this one star merely because he sees "absolutely no need for" it. Hey gerardrj, from now on don't give one star just because you don't think something's needed. If you don't need it, don't download it. Of course Mail supports multiple MAILBOXES -- not "accounts" -- but my wife has no interest in seeing or downloading my mail, and I don't want to bother with hers. She has multiple mailboxes and so do I. With this app, she can deal with her multiple mailboxes, I can deal with mine, and we're copacetic. Thanks to the author for one of those "I've been looking for this for a long time" solutions.
