Perhaps related to the other errors I just reported, I also see a few of these in the dovecot-2.0.3 logs: lda(pid 8212 user user3): Error: Opening INBOX failed: Mailbox doesn't exist: INBOX lda(pid 8212 user user3): msgid=<201009240906510365.1gj1fpfhrhhm9@mail>: save failed to INBOX: Mailbox doesn't exist: INBOX lda(pid 8212 user user3): Error: BUG: Saving failed to unknown storage

and some clients report receiving this IMAP error: tag NO Mailbox doesn't exist: INBOX

For newly created users that don't have the Maildir directory created yet? I guess there could be some race condition there in the initial INBOX creation.. This is with normal mail_location=maildir:~/Maildir or something?

although in general mail delivery and IMAP work, and these users' Maildir++ directories do exist and look OK. This error did not occur for the user1 or user2 in the other report.

I think that happens only once and afterwards the INBOX is created and stuff works ok?

And here's a third kind of error: imap(pid 5722 user user4): Error: stat(/path/to/mail/user4/tmp/ͼ) failed: No such file or directory imap(pid 5722 user user4): Error: Internal quota calculation error

That path looks like a memory munge.

Yeah, it does look like some memory corruption or something. And yeah, possibly also related to that filename="" bug. This is with Maildir++ quota? Did OSX have valgrind yet (or do you have something equivalent)?

This was caused by the lost tmp/ directories, which was fixed by that patch I sent. Also http://hg.dovecot.org/dovecot-2.0/rev/5b0a1974fc6f fixes recreating these missing tmp/ dirs.
