[Dovecot] Maildir Subsystems
by Aaron Wiebe 23 Feb '08

23 Feb '08

Greetings - new to the list, so apologies of I'm asking questions that have been brought up before. I work for a large email provider, currently using qmail, vpopmail and courier-imap. We tend to make fairly regular customizations of the software, and if you folks have any knowledge of courier's code layout, you probably can understand why we hate working on it. Anyway, I am looking at the possibility of migrating to dovecot, after a quick review of the code layout. It is MUCH nicer to read. But I have a few specific questions: 1. We customize our maildir system fairly heavily, and I'm wondering where the maildir code is located. Specifically, anywhere the app actually does work on disk related to folders, mail content and quotas. While I have reviewed the code in brief, I thought it would be easier to poke this list to get pointed in the right direction. 2. Courier works quite well over NFS for us, and I'm curious why your documentation covers NFS more specifically. What aspects of the filesystem are normally used that don't translate easily to work over NFS? Do you use stuff like inotify or atimes? 3. If anyone has any suggestions on how to migrate tens of thousands of imap users from courier to dovecot in a few hour window, I'd like to hear them :) Thanks, Aaron Wiebe

[Dovecot] Put existing mails (in Maildir) through sieve filter?
by Andreas Ntaflos 22 Feb '08

22 Feb '08

Hello list, the scenario: A user has about 30k mails in his Maildir (all in INBOX) and needs to apply filtering. Provided he writes a working .dovecot.sieve script, is there a way to put all those already delivered mails through Dovecot's LDA and thus have the sieve filter rules applied? Or is there any other way to apply sieve rules to already delivered mails? TIA Andreas -- Andreas "daff" Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

Hi all, this is my last try to get help before giving up. I red the dovecot-wiki several times, but it doesn´t work. I don´t know what´s wrong. If I open thunderbird I see the folder "public" but I cannot subscribe it. I have dovecot 1.0.10. Yes it´s a little bit old but it is the latest version under debian packages.

[Dovecot] Postfix on one host/Dovecot (mailboxes) on another - How?
by k bah 22 Feb '08

22 Feb '08

Hi, I'm using Dovecot 1.0.5 on OpenSUSE 10.3. I run postfix/amavis/clamav on one host, postfix uses LDAP to identify whether or not users exist. On this same machine I was running dovecot, so I used dovecot LDA on Postfix master.cf (as mentioned on http://heinous.org/wiki/Virtual_Domains,_Postfix,_Dovecot_LDA,_and_LDAP#Pos…) Now I want to run Dovecot on another machine, how should I configure postfix on that first machine? first machine: the domain my users know/use; webmail; postfix/amavis/clamav; mx record for domain all users have mail addresses; imapproxy (pointing to the second machine, where the imap server sits). second machine: just dovecot and user's mailboxes. (I need to keep this machine doing only this task, because of the load) Is there a way to do that just by adding a mailbox_transport to the first machine's postfix? thanks = Mobile (Volumetric) Concrete Mixers The innovative leader in the mobile concrete mixer industry.

[Dovecot] Deliver - Virtual users
by Tobias Balle-Petersen 22 Feb '08

22 Feb '08

Hello... I have dovecot 1.0.10 running with users in an LDAP database. Things are working as they should with IMAP. However, I can't seem to make deliver w. postfix work they way I want. My problems are: Mail to users who do not exist in LDAP or locally are accepted and mailfolders are created. I want mail to users that do not exist in LDAP or locally to be rejected. Mail is delivered to users even though they are over quota. Below I have included a bit of my log. This is what I see when sending a mail to an existing user. I don't understand the part that says: dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): lookup In my database users are stored as usernames without domains. Deliver seems to lookup the name with domain? The lookup ends with "unknown user". Then I wonder, why is the mail delivered if the user is unknown? I have included the "protocol lda" part from my dovecot.conf and the result of "dovecot -n". Can someone help me get this sorted out? Thanks, Tobias #################################################### Feb 22 11:31:40 mihoko postfix/smtpd[16944]: 2A8F7137E6: client=unknown[192.168.0.225] Feb 22 11:31:50 mihoko postfix/cleanup[17942]: 2A8F7137E6: message-id=<20080222103140.2A8F7137E6(a)frontdesk.kontrapunkt.dk> Feb 22 11:31:50 mihoko postfix/qmgr[2255]: 2A8F7137E6: from=<slik(a)kontrapunkt.com>, size=362, nrcpt=1 (queue active) Feb 22 11:31:50 mihoko dovecot: auth(default): master in: USER^I1^Itbp(a)kontrapunkt.dk^Iservice=deliver Feb 22 11:31:50 mihoko dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): lookup Feb 22 11:31:50 mihoko dovecot: auth(default): passwd(tbp(a)kontrapunkt.dk): unknown user Feb 22 11:31:50 mihoko dovecot: auth(default): master out: USER^I1^Itbp(a)kontrapunkt.dk^Iuid=1000^Igid=1000^Ihome=/home/vmail/tbp Feb 22 11:31:50 mihoko deliver(tbp(a)kontrapunkt.dk): msgid=<20080222103140.2A8F7137E6(a)frontdesk.kontrapunkt.dk>: saved mail to BLAH.SYNTS Feb 22 11:31:50 mihoko postfix/pipe[17950]: 2A8F7137E6: to=<tbp(a)kontrapunkt.dk>, relay=dovecot, delay=18, delays=18/0.01/0/0.08, dsn=2.0.0, status=sent (delivered via dovecot service) Feb 22 11:31:50 mihoko postfix/qmgr[2255]: 2A8F7137E6: removed #################################################### From dovecot.conf: protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)kontrapunkt.com # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. #mail_plugins = #mail_plugin_dir = /usr/lib/dovecot/modules/lda mail_plugins = quota # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. auth_socket_path = /var/run/dovecot/auth-master # Enabling Sieve plugin for server-side mail filtering mail_plugins = cmusieve } #################################################### dovecot -n # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap listen: localhost:143 ssl_listen: *:993 ssl_cert_file: /etc/ssl/certs/imap.kontrapunkt.com.crt ssl_key_file: /etc/ssl/private/imap.kontrapunkt.com.key ssl_key_password: XXXXXXXXXX disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting: System ready. login_process_per_connection: no valid_chroot_dirs: /home/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%n/mail:INDEX=/var/indexes/%n maildir_copy_with_hardlinks: yes mail_plugins: quota imap_quota trash imap_client_workarounds: delay-newmail auth default: username_format: %n verbose: yes debug: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%n allow_all_users=yes userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail plugin: quota: maildir:storage=10 trash: /etc/dovecot/dovecot-trash.conf sieve: /home/vmail/%n/.dovecot.sieve

This way I'm the only one to see your post and I'm not sure that I can help. Also other users may benefit from your experience if it's available online. When you post to doveco(a)dovecot.org a copy is sent to me anyway. I'm not sure that I can help. I think you should check your permissions on the folder. And I think you should try with: fileinto "Junk"; Instead of: fileinto ".Junk"; (without the preceding dot that is) The preceding dot will automatically be added to the folder name by dovecot so it may create confusion if you use it too. Dovecot always uses the dot-prefix on folder names in the file system but this isn't really part of the IMAP/Sieve folder name that you wanna use. Regards, Mikkel

[Dovecot] verbose IMAP logging
by Robert Chien 22 Feb '08

22 Feb '08

Hi, Is there a way to enable telemetry or debug-level logging in Dovecot IMAP, to see the exact IMAP command issued by the client and server? E.g. to confirm if a certain MUA is indeed using IMAP IDLE, or if it's doing LIST or LSUB. The IMAP connection is made over TLS/SSL, so tcpdump won't work. Thanks, Robert
