[Dovecot] dsync is seriously broken when syncing maildir and mdbox
by interfaSys sàrl 28 Sep '10

28 Sep '10

Hello, I thought mdbox was production ready, but it seems to me that (in 2.0.4) it's quite broken. 1) The documentation only running this to convert from maildir to mdbox: *dsync mirror maildir:~/Maildir* but based on my experience and on posts on the mailing list, it's not enough. A namespace has to be defined and it's not clear whether / or . should be used as a separator. I tried with a dot first and the INBOX folders were empty. It seemed to work better with / 2) After having defined a namespace, running dsync again makes it spit tons of errors Error: Can't rename mailbox INBOX_28c716242e53784cc9030100d3b51c5c to INBOX: Target mailbox already exists Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and INBOX_4536121fce3ca14cf8c40c Info: INBOX/spam: only in dest Info: INBOX: only in source Each run will create more folders with GUIDs attached to the folder name. 3) Deleting these folders after having moved their content to the properly named ones seems impossible. I see a long list of folders in the bin and when I hit "Empty bin" in Thunderbird, nothing happens. There must must be a caching issue, because if I click on the folder, I'm told these folders don't exist. If I dsync again, I still have conflicts, with folders that are in the bin and then with new copies of INBOX Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX and Trash/INBOX_4536121fce3ca14c Error: Mailboxes don't have unique GUIDs: 4536121fce3ca14cf8c40000d3b51c5c is shared by INBOX_4536121fce3ca14cf8c40000d3b51c5c At that stage, the newly created INBOXes cannot be deleted because they already exist in the bin. I renamed those folders, moved them to the bin, emptied the bin And it's still not fixed when running dsync Error: Mailboxes don't have unique GUIDs: 1a6f000a9751784c12030100d3b51c5c is shared by Sent and Trash/5 Info: Trash_INBOX_bb088f159336a14cc6bf0000d3b51c5c: only in dest Error: Can't rename mailbox INBOX to Trash_3: Renaming INBOX isn't supported. Why can't folder properly be deleted? I never had that problem with Maildir. Cheers, Olivier

[Dovecot] Command to get proxy connection count
by Brad Davidson 28 Sep '10

28 Sep '10

Timo, I'm trying to get a count of active proxy sessions on a given Director. I can of course enable verbose_proctitle and parse the 'N connections' string out of ps output or /proc/pid/cmdline. Is there a better way to do that, perhaps with doveadm? Goes back to needing a command for proxy and director ring status, I guess. -Brad

[Dovecot] Can't delete certain messages
by Karl Davenport 28 Sep '10

28 Sep '10

Running Dovecot version 1.0.10 on Ubuntu Server 8.04 amd64 (ext3). Some users have emails that will not go away. They delete them and the message is moved to the trash folder only to reappear when the mailbox is refreshed. Moving the message manually to another folder has the same effect. We are running Thunderbird as our email client, though I have tried using other clients to remove the messages. Here is my config: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_privileged_group: mail mail_location: maildir:/home/%u/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam userdb: driver: passwd #End dovecot.conf Thanks in advance. -- Karl Davenport WaveCom Communications karl(a)wavecom-it.com 435-656-0972

[Dovecot] mail_fsync=never doesn't work?
by Attila Nagy 28 Sep '10

28 Sep '10

Hello, I've tried to set the above in Dovecot 2.0.3, but according to ktrace (FreeBSD) it still fsync()s a lot (pop3 processes for example). Is this switch useful at all?

[Dovecot] Statistics
by Pierre 28 Sep '10

28 Sep '10

HI list, According to this: http://webcache.googleusercontent.com/search?q=cache:QMGLz9SVNdwJ:www.dovec… << # Use statistics to automatically distribute heavy users to different servers * v1.2 can export very detailed statistics via plugin >> I can't find this "detailed statistics" plugin, I only found this: http://www.dovecot.org/patches/2.0/stats-plugin.c But it only seems to add a "stats" IMAP command. Please can somebody confirm or give me a link to this plugin ? I really need to identify "heavy" users,so this plugin may be really usefull for me. Thanks a lot, Pierre

[Dovecot] dovecot 2.0.4 imap service error

Just upgraded from 2.0.3 to 2.0.4 and getting this message in the logs (repeated several times) master: Error: service(imap): child 9631 killed with signal 11 I'm using mdbox and had no problems using 2.0.3 until I upgraded this morning.

[Dovecot] Fixed mailbox id?
by Dieter Knopf 28 Sep '10

28 Sep '10

Hello, I have many Sieve rules and searching for a way to "track" renamings/moving of mailboxes (folders) on my IMAP server. Is there a unique ID for every folder available? I don't think there, i found no ID inside my folders :( If not, it think i need to create a ID-file for every folder and after that i can track the folders and update the rules =) Thanks

Hi, I don't remember how to turn off debugging for AntiSpam plugin ... it still writes it's debug output to /var/log/debug.log ... But everything works fine now - so it can be turned off since it just wastes my Memory ... Thanks & Regards

[Dovecot] Need more info on new fsync switch
by interfaSys sàrl 27 Sep '10

27 Sep '10

Hello, I wanted to improve performance by disabling fsync where I can, but the example in the Wiki is outdated http://wiki2.dovecot.org/MailLocation/LocalDisk # Enable for IMAP/POP3 fsync_disable = yes protocol lda { # Disable for LDA/LMTP fsync_disable = no } Can that simply be replaced by the default config which is mail_fsync = optimized Or should it be replaced by # Enable for IMAP/POP3 mail_fsync = never protocol lda { # Disable for LDA/LMTP mail_fsync = optimized } Cheers, Olivier
