dovecot & Apple Mail & maildir & lots of Mail
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

My Maildir is 61G in 237493 messages spread over 424 folders. dovecot handles this effortlessly. "doveadm mailbox status -t all '*' -u <name>" returns almost instanly on a warm cache. Thunderbird does fine too.

Hi,
Using Mac Mail with 9 mail accounts, more than 150 folders, and 1000s of mails, I get far too many problems lately, and not only on dovecot, so I would say the problem lies with Mac Mail, and even more if you installed Yosemite. As far as I know dovecot handle very well accounts with 100000s email even if the size is very big.
And BTW, looking for a fast and reliable mail client for Mac, to replace Mac Mail, any suggestion?
Regards, Thierry

One thing that happened twice now is that files like these appear: /home/user/Mail/dir/cur/.imap/1312388125.11233_28123.host:2,S/dovecot.index.log but they don't go away for days.
How can that happen? Can/should I delete these files? Thomas

I finally found out what the problem was.
My mail is in the folder "$HOME/Mail". For that reason, dovecot assumed I must be using mboxes (even though it only contains maildirs), and handled each mail = maildir file as a separate mbox.
I've renamed "$HOME/Mail" to "$HOME/Maildir" and configured procmail and mutt to look there, and now it works fine even with Apple Mail. Thomas
