Hello,

I'm testing some configurations, in the process I used a wrong user setting causing POP3 (get new messages) to fail, whereas IMAP was still working.

An easy fix was to remove the entire /var/cache/dovecot/1012/ directory, both index and index/control were re-created and do work. So my guess is that the existance of the indexes causes some trouble when just the control information is missing.

Here is what I had done: The mailbox of "dvtest" was fully working with the correct setting from the config file: mail=maildir:/home/dvtest/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/control (no "/index" in the CONTROL= part).

Then I created a LDAP entry for the user dvtest wrongly: mail=maildir:/home/dvtestMAIL/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/index/control The CONTROL= ended in "/index/control" rather than just "/control".

(Note: I also mv'ed /home/dvtest to /home/dvtestMAIL in order to see, whether the LDAP attribute is getting used.)

Afterwards IMAP is working, but POP3 returns "Couldn't init INBOX: Unknown error"; Thunderbird displays the error: "The STAT command did not succeed. Error getting message number and sizes. Mail server ux-2s11-9 responded: Couldn't sync mailbox."

When I correct the LDAP attribute, hence the CONTROL= path ends in "1012/control" again. The mailbox is working with POP3 again.

The INBOX of the erroreous control path does not contain any dovecot-* files? The message I deleted and expunged (see logs) were from the INBOX. /var/cache/dovecot/1012/index/control# lr .: total 16 drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ./ drwx------ 12 dvtest dvtest 4096 2007-03-07 09:34 ../ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:36 .Addresses/ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:35 .INBOX/

The attached file contains the full log of a session POP3 (get new messages), IMAP, expunge in INBOX, POP3 again.

I also selected the mailbox Adresses once, to see if it is working.
