[Dovecot] Some messages appear twice
by Dominik Schulz 28 Jul '11

28 Jul '11

Hi, I'm using Dovecot 1.2.15 on Debian. On some clients, at least KMail, some messages (especially older ones) appear twice in the message list of the client. This is really annoying. Can anyone give me a hint on how to solve this issue? -- Best Regards, Dominik Schulz

[Dovecot] DIsctionnary flat file format for shared mailboxes ?
by Frank Bonnet 28 Jul '11

28 Jul '11

Hello I would be grateful if someone could send an example of a dictionnary flat file used by the shared mailboxes feature, it has very few here so a flat file will be enough I think. Thank you

Hi. I have a quite problem with dovecot and sieve on Debian Squeeze. I'm trying to enable sieve plugin into dovecot, but something is deeply wrong. I hope that this is the right place to give some help. There are no errors or warning messages, simply sieve don't works. For the big picture about my mail server you can follow this link http://www.linux-archive.org/debian-user/555576-postfix-virtual_transport-m… and here there is my specific request on Debian User List http://www.linux-archive.org/debian-user/557551-sieve-dovecot-squeeze-help.… here my dovecot -n output # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s lda disable_plaintext_auth: no 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 first_valid_uid: 102 mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n mbox_write_locks: fcntl dotlock 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 lda: log_path: /var/vmail/dovecot-deliver.log postmaster_address: info(a)**********.it auth_socket_path: /var/run/dovecot/auth-master mail_plugins: cmusieve auth default: mechanisms: cram-md5 plain login debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: postfix plugin: sieve_global_path: /var/vmail/globalsieverc sieve_dir: ~/sieve sieve: ~/.dovecot.sieve sieve_global_dir: /var/vmail/sieve sieve_maxscriptsize: 128 Any suggestions?

[Dovecot] Problem with client login in 1.2.17
by John O'Brien 27 Jul '11

27 Jul '11

Hi, I have been using CentOS 5.5 with Dovecot 1.0.7. My client apps login with TLS/SSL using an postgres database for username and password authentication. I developed a plugin that added an additional IMAP command. I want to eventually migrate to release 2.0 but have decided to make this a two step process. I have started with 1.2.17 as I hope this would be a smaller step along the way. I have installed 1.2.17 from source an installed. Rebuilt my plugin and installed and set about updating the dovecot.conf file. Installing the SSL certificate etc..... I have tested the 1.0.7 configuration previously using a standard IMAP mail client. When I try with 1.2.17 I can't seem to get logged in. ==> /var/log/maillog <== Jul 27 21:48:26 email dovecot: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=192.168.1.10 rip=202.81.69.135 lport=10143 rport=58641 resp=ADYxNDE0NjI3NDM2AFExcjQwNHVD Jul 27 21:48:26 email dovecot: auth-worker(default): pam(john,202.81.69.135): lookup service=dovecot Jul 27 21:48:26 email dovecot: auth-worker(default): pam(john,202.81.69.135): #1/1 style=1 msg=Password: Jul 27 21:48:28 email dovecot: auth-worker(default): pam(john,202.81.69.135): unknown user Jul 27 21:48:28 email dovecot: auth(default): sql(john,202.81.69.135): query: SELECT password FROM ivms_iphone WHERE username='john' Jul 27 21:48:28 email dovecot: auth(default): client out: OK 1 user=john Jul 27 21:48:28 email dovecot: auth(default): master in: REQUEST 2 28178 1 Jul 27 21:48:28 email dovecot: auth(default): passwd(john,202.81.69.135): lookup Jul 27 21:48:28 email dovecot: auth(default): passwd(john,202.81.69.135): unknown user Jul 27 21:48:28 email dovecot: auth(default): sql(john,202.81.69.135): SELECT home, uid, gid FROM users WHERE username='john' Jul 27 21:48:28 email dovecot: auth(default): master out: USER 2 john home=/var/imap_mail/john uid=50gid=500 Jul 27 21:48:28 email dovecot: IMAP(john): Loading modules from directory: /usr/local/lib/dovecot/imap/ Jul 27 21:48:28 email dovecot: IMAP(john): Module loaded: /usr/local/lib/dovecot/imap//lib20_mail_log_plugin.so Jul 27 21:48:28 email dovecot: IMAP(john): Module loaded: /usr/local/lib/dovecot/imap//change_passwd_plugin.so Jul 27 21:48:28 email dovecot: IMAP(john): Effective uid=500, gid=500, home=/var/imap_mail/john Jul 27 21:48:28 email dovecot: IMAP(john): maildir: data=john Jul 27 21:48:28 email dovecot: IMAP(john): maildir++: root=john, index=, control=, inbox=john Jul 27 21:48:28 email dovecot: imap-login: Login: user=<john>, method=PLAIN, rip=202.81.69.135, lip=192.168.1.10, TLS Jul 27 21:48:28 email dovecot: IMAP(john): Namespace : Using permissions from john: mode=0700 gid=-1 ==> /var/log/secure <== Jul 27 21:48:26 email dovecot-auth: pam_unix(dovecot:auth): check pass; user unknown Jul 27 21:48:26 email dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=john rhost=202.81.69.135 Jul 27 21:48:26 email dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user john I have the following in the .conf file auth_verbose=yes auth_debug=yes auth_debug_passwords=yes mail_debug=yes verbose_ssl=yes Also note the following differences in behaviour between Dovecot 1.0.7 and 1.2.17 $ telnet new_system_1.2.17 10143 Trying 192.168.1.10...

[Dovecot] sieve, vacation - lda-dupes being ignored?

EVERY time the user checks his mails. I haven't heard any user complaint about this, but perhaps nobody tried this before. I recreated this situation (copy old qpopper message INBOX -> tmpbox -> INBOX) and produced two messages with identical X-UIDL headers, but according to the Wikipedia entry for POP3: Comparison with IMAP Clients that leave mail on servers generally use the UIDL command to get the current association of message-numbers to message identified by its unique identifier. The unique identifier is arbitrary, and might be repeated if the mailbox contains identical messages. This is echoed in RFC1939 (page 11-12) While it is generally preferable for server implementations to store arbitrarily assigned unique-ids in the maildrop, this specification is intended to permit unique-ids to be calculated as a hash of the message. Clients should be able to handle a situation where two identical copies of a message in a maildrop have the same unique-id. So POP3 UIDLs are not guaranteed to be unique, especially if the messages are the same. Perhaps some mail readers are making unwarranted assumptions about the uniqueness of UIDLs: http://www.eggheadcafe.com/software/aspnet/33485042/duplicate-messageiduidl… https://www.ritlabs.com/bt/view.php?id=3599 Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] phantom new message notification
by Stan Hoeppner 26 Jul '11

26 Jul '11

I've developed a phantom new message notification on a single IMAP folder in Thunderbird. I've deleted the Dovecot index files for this problematic folder, and I've deleted the .msf file in the Tbird profile. Neither of which solved the problem. The only other time I've run into something similar was with CONDSTORE quite a long time ago, but that affected all folders, not just one. Any ideas? -- Stan

[Dovecot] drac plugin "net_ip2addr() failed: Operation not permitted"
by Michael Moritz 25 Jul '11

25 Jul '11

Hi, I'm trying to get the drac plugin working (again) but I'm stuck with the following message: Restarting IMAP/POP3 mail server: dovecotEDRAC: net_ip2addr() failed: Operation not permitted This is on a Debian Squeeze box, dovecot version 1.2.15-7, drac version 1.12 Looking at the source it should print the IP in the brackets of net_ip2addr. The fact that it's just empty made me think that I may need to set an environment variable. I tried IP="127.0.0.1" in /etc/default/dovecot and as export but to no avail. Any ideas? Thanks, mimo

[Dovecot] passwd not found
by Erik - versatel 25 Jul '11

25 Jul '11

If I use in dovecot.conf passdb passwd-file { args = /etc/dovecot/vhosts/%d/etc/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } I get an authorisation failure in my mail.log file. If I use passdb passwd-file { args = /etc/dovecot/vhosts/shadow } userdb static { args = uid=virtual gid=virtual home=/var/mail/vhosts/%d/%u allow_all_users=yes } This works !!! (without the %d) in the passdb passwd-file Than the %d/%u is correctly rewritten in the userdb static. PS I have in the passwd-file the username@domain and the username documented for testing. I think there is some problem with the %d (DOMAIN) How can I check if %d is filled ?? And how can i make different authorisationdirs and files per domain.
