I’ve managed to infect my IMAP account with a hierarchy of folders that cyrus isn’t letting me delete on-wire. Normally this wouldn’t be a problem, but alas, I’m on Mac OS X Server, so it is. Apple has built a semi-usable GUI tool for mail administration, but you really can’t do any low-level operations with it. Nevertheless they’ve decided that it’s enough, so they ship the whole thing without a working cyradm. What’s up with that?
I love Apple’s practice of using proven open source tools as a basis for their products, but crippling the results like this isn’t making anyone happy. (The same is true of Apple's bundled version of PHP, which is configured in a particularly useless fashion.)
