[Dovecot] Mailbox autocreate feature cannot create folders
by interfaSys sàrl 08 Jan '14

08 Jan '14

Hello, The "new" way of creating default mailboxes doesn't work for us. There seems to be a permission problem. We get this in the logs: imap(testuser(a)domain.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy That error message has nothing to do with NFS (not used) or /var/mail and appears every time an app is requesting a list of folders via IMAP and only if we enable the autocreate feature. We're using mdbox, emails are delivered via LDA and the folder permissions look like this: # la /home/user/imap/domain.com/testuser/mdbox/mailboxes/ total 5 drwx------ 3 user mail 3B Jan 5 19:33 INBOX drwx------ 3 user mail 3B Jan 5 19:33 . drwx------ 4 user mail 8B Jan 7 02:43 .. The mailbox definitions used come straight from the wiki: http://wiki2.dovecot.org/MailboxSettings I've enabled debugging, but there is no mention of the mailboxes to create: Debug: dict quota... Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox Debug: fs:... Debug: acl:... ... Here is what works: - Autocreate plugin - Creating folders via various clients So, it seems Dovecot can create folders, just not using that feature. If that's not a bug, would there be a way to make it work without altering permissions? Cheers, Olivier

[Dovecot] inotify max_user instances
by Charles Marcus 07 Jan '14

07 Jan '14

Hello, Timo, last year when you remoted into our server and performed the migration from courier-imap, we ran into this issue, and you solved it by doing: echo 1024 > /proc/sys/fs/inotify/max_user_instances Then you said you were going to solve this permanently by changing the init script... Here is what you said (this is from the skype chat): [2012-06-04 10:40:43 AM] timosirainen: probably put to dovecot init script or something I guess I could manually modify my init script, but I'm clueless as to where.how.

[Dovecot] need assistance migrating between apple servers
by Raymond Norton 06 Jan '14

06 Jan '14

I am attempting to move imap folders from an Apple Snow Leopard server to a new Apple Mavericks server. Dovecot --version is not working , but I believe the old server is running dovecot 1.1.2 and can confirm the new one is running 2.2.x. I have tried taring and moving folders, but have not been able to get the transfered messages and folders to show up in user accounts (new messages show up fine). I have attempted to recreate index files, but that has not worked either. The last attempt I made to migrate was to use dsync, but it does not exist on the old server and I do not see a way to install it. What method would work best to migrate or move files and folders from the old server and get them to show up for clients on using the new server? -- Raymond Norton LCTN 952.955.7766 Sent from My Desktop

Hi, I am trying to find a way to list my virtual mailboxes hiding the namespace prefix into my imap client. Fore example now my “All” mailbox is listed under virtual/ as: Inbox Sent Drafts Spam Trash virtual All I would like to list as this: Inbox Sent Drafts Spam Trash All This is my 10-mail.conf: http://pastebin.com/DumEbbmy and this is my 15-mailboxes.conf: http://pastebin.com/QFzWGzyC I thought that the list = children paramenter would do but it did not. Thank you

[Dovecot] [SIEVE] Locking Errors with vnd.dovecot.duplicate Extension
by Daniel Parthey 06 Jan '14

06 Jan '14

Hi, we are running a 4 host setup which each hosts a director+mailbox which is mounted via NFSv4 from a DRBD cluster. * Dovecot upstream release 2.1.16 * Doveadm batch subcommand fix - http://hg.dovecot.org/dovecot-2.1/raw-rev/850b5d8bbcc9 * Pigeonhole release 0.3.4 Now we would like to remove duplicate Mails using the vnd.dovecot.duplicate extension using a SIEVE script like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox", "regex", "vacation", "variables"]; if duplicate { fileinto :create "Trash"; } But as soon as we start delivering duplicate mails, we're sometimes getting locking errors from the mailbox (which is responsible for the user) according to the director: Dec 27 16:36:30 10.129.3.213 dovecot: lmtp(27975, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:33 10.129.3.213 dovecot: lmtp(27987, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:35 10.129.3.213 dovecot: lmtp(27994, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28011, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28013, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:38 10.129.3.213 dovecot: lmtp(28017, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:39 10.129.3.213 dovecot: lmtp(28025, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:42 10.129.3.213 dovecot: lmtp(28037, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:43 10.129.3.213 dovecot: lmtp(27973, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Configs and Error log is attached.

[Dovecot] disable_plaintext_auth = yes not showing in doveconf -n output?
by Charles Marcus 04 Jan '14

04 Jan '14

I have it set, but it doesn't show up. However, I noticed that it does show as enabled by default in doveconf -a output. Is this why it doesn't show up in doveconf -n output? -- Best regards, Charles
