[Dovecot] Dovecot and Phpgroupware compatibility
by Carlos Xavier 27 May '09

27 May '09

Hi, I am resending this email, since the fist one didn't hit the list. Recently we moved our server from mbox format to Maildir format and started using Dovecot. Almost all the users are very happy with this, since the speed had increased very much. I used mb2md to do the conversion and on this task all the mailboxes that had "." (dot) on their names were converted to "_". But there is one issue with this, we also use the webmail that comes with Phpgroupware, and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft and so on. When their names were changed the sent messages didn't get saved anymore, so I had to move them back to the old names. After that the sent messages returned to be saved again, but another trouble showed up. As they start with .INBOX and have "." on the names, Dovecot shown them as a subdirectory of the INBOX and we got some people upset with this. I need help on configuring Dovecot to not show them this way, because if you reed the .INBOX.Sent either on the webmail or by Outlook, the field displayed is the sender, witch is not desired. When I did the conversion, to keep the compatibility with the old server (quota, avoid I/O bottleneck, etc), I set two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at the user home. We are using Dovecot version 1.1.13, and below is the relevant configuration on use. namespace public { prefix = "#mbox/" separator = / inbox = yes list = no location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control } namespace private { separator = / prefix = location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control inbox = no } Best Regards, Carlos Xavier.

Hi all Trying to setup dovecot with mysql and postfix, I have configured it as given below. thecot user has the dovecot group as primary, and is also a member of mail and dovecot-users. Still, it can't setgid to dovecot-users. I tried changing the shell for the dovecot user to something useful and chmod'ing a file to dovecot-users, and it work well. Still, no mail comes through and dovecot gives me this error deliver(roy(a)somedomain.com): 2009-05-23 15:02:52 Fatal: setgid(115) failed with euid=115, gid=114, egid=114: Operation not permitted Any ideas? roy # Dovecot config # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%d/%n auth default: default_realm: eventchief.com verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: dovecot group: mail -- Roy Sigurd Karlsbakk (+47) 97542685 / 98013356 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

Hi Timo, wiki says --------- Shared mailbox listing ..... You could use any dictionary backend, such as SQL or Berkeley DB, but a simple flat file should work pretty well too: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } .... -------- could you include an example for having acl_shared_dict in sql ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Secure Sockets Layer client certificate authentication
by Stephen Feyrer 26 May '09

26 May '09

Hi everyone. Please note, I've asked a very similar question before and I apologize for sounding like a broken record. Well here it goes. What I want to do is authenticate my users using a certificate. Thereby authenticating both the user and server with strong tokens that are centrally managed. In the worst case scenario the user should only need to enter a password for the certificate store and then the certificate should trigger the appropriate level of access to their account. Is Dovecot the correct tool for the job? If yes then, how? Else if not, then what would you recommend? I have tried setting the auth mechanism to anonymous without any joy. My password file is set with nopassword. All my certificates work well with the Secure Sockets Layer system. This is the configuration I am currently running: # 1.2.beta1: /opt/etc/dovecot/dovecot.conf # OS: Linux 2.6.12.6-arm1 armv5tejl log_path: /opt/var/log/dovecot.log info_log_path: /opt/var/log/dovecot-info.log protocols: imaps ssl_ca_file: /opt/etc/ssl.ca/cacrl.pem ssl_cert_file: /opt/etc/ssl.ca/newcerts/imap.cer ssl_key_file: /opt/etc/ssl.ca/private/imap.key ssl_parameters_regenerate: 24 ssl_cipher_list: ALL:!LOW:!SSLv2 ssl_verify_client_cert: yes disable_plaintext_auth: yes verbose_ssl: yes login_dir: /opt/var/run/dovecot/login login_executable: /opt/libexec/dovecot/imap-login login_user: guest login_processes_count: 2 login_max_processes_count: 4 mbox_write_locks: fcntl mail_process_size: 512 imap_client_workarounds: outlook-idle tb-negative-fetch auth default: user: admin verbose: yes debug: yes ssl_require_client_cert: yes ssl_username_from_cert: yes passdb: driver: passwd-file args: /opt/etc/dovecot/h.org/passwd userdb: driver: passwd This is a log of a login attempt: dovecot: May 25 11:55:58 Info: auth(default): new auth connection: pid=22556 dovecot: May 25 11:56:08 Info: imap-login: Valid certificate: /O=home.org/emailAddress=admin(a)nas2.h.org/L=W/ST=C/C=G/CN=h.org dovecot: May 25 11:56:08 Info: imap-login: Valid certificate: /C=G/ST=C/O=h.org/OU=K F/CN=k dovecot: May 25 11:56:10 Info: auth(default): new auth connection: pid=22585 dovecot: May 25 11:56:16 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured valid-client-cert cert_username=k lip=10.1.1.245 rip=10.1.1.1 lport=993 rport=53430 dovecot: May 25 11:56:16 Info: auth(default): client out: CONT 1 dovecot: May 25 11:56:16 Info: auth(default): client in: CONT<hidden> dovecot: May 25 11:56:16 Info: auth(default): passwd-file(k,10.1.1.1): lookup: user=k file=/opt/etc/dovecot/h.org/passwd dovecot: May 25 11:56:16 Info: auth(default): passwd-file(k,10.1.1.1): No password dovecot: May 25 11:56:16 Info: auth(default): client out: OK 1 user=k dovecot: May 25 11:56:16 Info: auth(default): master in: REQUEST 6 22164 1 dovecot: May 25 11:56:16 Info: auth(default): passwd(k,10.1.1.1): lookup dovecot: May 25 11:56:16 Info: auth(default): master out: USER 6 k system_user=k uid=500 gid=100 home=/ dovecot: May 25 11:56:16 Info: imap-login: Login: user=<k>, method=PLAIN, rip=10.1.1.1, lip=10.1.1.245, TLS With this configuration the client will connect over ssl and identify itself with a certificate but a client password is still required. -- Regards Stephen.

by Chantal Rosmuller 26 May '09

Hi list, I use dovecot 1.1.11 on ubuntu 9.04, when I want to send a message to an email adres on this mailserver I get this error: status=bounced (Command died with signal 11: "/usr/lib/dovecot/deliver". The folders where the email should be delivered are created so it does not look like a permission problem. I connect to a mysql database where the email accoutn info is stored, this works. I use the same setup on an ubuntu 8.04 server with dovecot 1 and I have no problems on that server. What am I overlooking here?
