I am using Dovecot 2.3.4.1 with maildirs. Just found out that MacOS Mail clients cannot work with nested folders, presumably because the MacOS Mail does not understand "." as the IMAP separator.
This is not correct. Mac Mail has no problems with nested folders and never has had any problem with nested folders. I have always used the '.' separator and I've had a 'Root' mail folder with subfolders since at least 2004.
I think I have already posted this link: https://discussions.apple.com/thread/8347018
Also this: http://hints.macworld.com/article.php?story=2007090423071517 It contains weird advice but at least proves that the problem exists for *some* people. See also the comments therein.
I don't want to break mail for 50 people just to please one Mac Mail user. The users are advanced developers actively using mail sorting rules, nested folders etc.
And what makes them think nested folders do not work?
I don't have the exact error message from him but it was pretty obvious about a folder "foo/bar/bob" being non-existent or inaccessible. And indeed, it's "~/Maildir/.foo.bar.bob" on the IMAP server's disk, there are no subdirectories for mail folders.
