I'm having some trouble with Apple Mail 6.3 (1503) and Smart Mailboxes under 10.8.3. When I create Smart Mailboxes they work just as one would expect them to. When I quit Mail and re-open it, they're gone as if I would have never created them. I found a similar issue with an earlier version of Mac OS X where deleting the SmartMailboxesSomething.plist in ~/Library/Mail/ fixed the problem. This does not seem to apply for OS X's current version anymore.

I filed a bug about this:

This happens on both my MacBook Air and my iMac. Both are running OS X's latest version.

Anyone know how to fix this?

Sorry, I tired but can not replicate our problem. – Buscar웃 Apr 20 '13 at 18:38
FYI--I use gmail in mail. – Buscar웃 Apr 20 '13 at 18:39
I use three Gmail accounts and one different as well. I think it's some kind of permissions error. Maybe Mail can't write to the file that stores the Mailboxes. I did already repair my disk permissions, but that didn't help. – flohei Apr 21 '13 at 7:10
Not that it should matter, but since there are multiple ways, how do you create them. – Buscar웃 Apr 21 '13 at 9:12
I create them using the + button in the lower left corner of the Mailbox list view. – flohei Apr 21 '13 at 13:02

I filed a radar (rdar://13700673) with Apple and after a few mails back and forth they figured out how to solve the problem:

chmod -a 'everyone deny write,delete,append,writeattr,writeextattr,chown' ~/Library/Mobile\ Documents/com~apple~mail/Data/MailData/* ~/Library/Mobile\ Documents/com~apple~mail/Data/MailData/Signatures/*

Looks like I had some permission issues on that files.

I would troubleshoot by quitting Mail, moving all Mail app preferences to desktop, and restarting Mail.

Can you please add the list of all Mail preferences which would require copying? And maybe explain how this would differ from the things the OP already tried (unsuccessfully). – patrix Apr 21 '13 at 11:43
