It can login. It can create messages. It can create folders. It does all of this as the user that owns the account. That's perfect. But, if the INBOX doesn't exist (even though all the folders leading up to it do) it can't. That's silly. So now, when I create a new user account, instead of just creating /var/sites/domain.com/mail/username/ I have to create it plus /var/sites/domain.com/mail/username/new/ and /var/sites/domain.com/mail/username/cur/.
Whatever.
Also, they claim that, good IMAP clients will support the NAMESPACE features and automatically recognize where mail goes and where new folders should be created. Well… that's just peachy. But, why not just do it automatically and then even bad IMAP clients will work. How hard would it be to add a feature that says "if a folder is being referenced, for creation or access, or message copy, that doesn't start with "INBOX.", add it for them. Additionally, if a '/' is specified in the folder name, convert it to a '.'"? Then, all of the problems would be solved and ALL IMAP clients would work pretty well.
To make matters worse, Outlook Express seems not to recognize Courier's NAMESPACE features, so you have to make that setting by hand. And, Evolution, regardless of whether that setting is made or not, insists on showing mail folders under INBOX. Ugh.
