Hi - I am wondering if it is possible to encrypt individual mailboxes, rather than encrypting my entire Library/Mail folder. The reason is that I really only have a need to encrypt client-related email, and if I could just do that, backing up my mail would be a lot leaner/faster because it wouldn't involve a giant 6GB sparse bundle.
Would I do this by just creating an application association from Mail.app to those individual mailbox files? Is that the intended use of application associations? I just want to double check this question because I am kind of paranoid about getting it wrong and somehow messing up backups...
Thanks!
