We're using dovecot 2.1.3 and I've been doing some testing with 2.1.7.
We have shared mail (maildir) folders working along with our default
mbox mailboxes. Our problem is trying to get this to work in a
reasonable fashion with our iPhone or iPad mail.app clients. It's well
known that they don't honor the subscription list; they show all
available mail folders and do not collapse trees of folders. I have 381
folders in directories under mail. Normal clients are fine, but this is
unmanageable in IOS.
What we have been doing is changing the mail prefix for the iPhone to a
subfolder, then using soft links to point to the most commonly used
folders we use. This works, but when one changes the mail prefix, any
shared folders are not presented. I'm suspicious that this is a design
decision. If there is some way to make it work, I'd be very grateful.
Note the two 'sharedimap' folders listed in the first 'list'.
Note that if I change the prefix for that shared namespace to
'iphonemail/', it does present my shared folders as well as anything in
a personal iphonemail directory. However, 'select' didn't work with the
personal folders. My guess is it's mostly due to the difference in mail
formats between the two (mbox & maildir). But, it does show that
somewhere in the code it's checking the mail prefix against namespaces
and not displaying shared folders in non-default prefixes. I wish this
were a configurable option.
thank you
