Mail and Mailboxes - how to rebuild/reindex
all at once? I don't want to do it one by one = isn't there any way to do a rebuilding and/or reindexing of Mail [all mailboxes] and its mailboxes all at once?
Also, I have a few SmartMailboxes and moved things from them and deleted them on my iMac == and they came back. I've done it a couple of times and they still come back. I want them gone!
