Hi!
I have dovecot 2.1.12 running on a mail server, and recently configured Apple Mail to connect to it using secure IMAP, for the first time.
At the beginning it just showed the inbox and everything was fine, but then I wanted to look at some of my folders and found the 'subscribe' menu. When I opened it, Apple Mail went to discover what mailboxes there are, and that's where my trouble began.
It seemed to make good progress for some time (though slow -- over days), and now lists the mailboxes from starting with letters a to d on the left hand side (filling all the visible space, so there might be more). However, whenever Apple Mail gets focus, the cursor becomes a spinning rainbow circle and I can't interact with it.
I tried deleting the mail account and setting it up again. The inbox was shown again immediately and Apple Mail was usable, but the first time the cursor moved over the mailboxes on the left hand side, it froze again.
There were two imap processes on the server, one rather idle, the other eating CPU for about two minutes, then idling, and some time later it disappeared too.
My Mail directory is 31G with about 180 directories, each containing mails in maildir format.
Has anyone had similar issues?
Is my maildir too big for dovecot too handle?
How can I debug this?
Thanks, Thomas
