[Dovecot] How to setting shared Maildir
by mlus 12 Dec '08

12 Dec '08

Hello I'm dovecot bigginer from courier-imap. I used shared maildir in courier like this. 1) create maildir # maildirmake -S /home/shared 2) create maildirshared file # echo 'SHARE /home/shared ' > /etc/courier/maildirshared (use tabcode) 3) edit imapd config file IMAP_UMASK=022 IMAP_SHAREDINDEXFILE=/etc/courier/shared/index in courier, only 3 step. I read wiki (http://wiki.dovecot.org) about shared maildir, for example Shared mailboxes Access Control Lists Namespaces ..... but I can't understand at all . Please explain by using the concrete illustration ? thank you.

[Dovecot] Dovecot authentication not supported in Entourage
by jan gestre 12 Dec '08

12 Dec '08

Hi Guys, I recently configured an mail server running postfix + dovecot + mysql + postfixadmin, everything is running ok except for Mac Entourage clients which is a PITA IMO, I always get a authentication not supported error while thunderbird and outlook on windows don't. Any ideas or workaround? my dovecot version is dovecot-1.0.7-2.el5. here's the output of dovecot.conf and dovecot-sql.conf respectively: # dovecot -n # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/postfix/ssl/mail-cert.pem ssl_key_file: /etc/postfix/ssl/mail-key.pem login_dir: /var/run/dovecot//login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_access_groups: mail mail_location: maildir:/home/virtualmail/%d/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 user: nobody passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: virtualmail group: mail # cat /etc/dovecot-sql.conf [root@mail ~]# cat /etc/dovecot-sql.conf driver = mysql connect = host=localhost dbname=postfix user=dovecot password=dovecot69 default_pass_scheme = MD5 user_query = SELECT '/home/virtualmail/%d/%n' as home, 'maildir:/home/virtualmail/%d/%n' as mail, 150 AS uid, 12 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' # Get the password password_query = SELECT username as user, password, '/home/virtualmail/%d/%n' as userdb_home, 'maildir:/home/virtualmail/%d/%n' as userdb_mail, 150 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' TIA.

[Dovecot] Duplicate suppression from remote lists?
by Adam Seering 12 Dec '08

12 Dec '08

Hi, I have a setup where users on my server who are subscribed to several lists on a (remote) weirdly-configured listserver are getting many duplicate e-mails. I know why this is happening; but I don't have control over that listserver so I can't fix it. Is there a way for me to suppress duplicates from within Dovecot? The duplicates do all have the same (otherwise-unique) message ID. "dovecot --version" gives 1.0.rc15. I'm using exim for SMTP. I'm also using dovecot-lda, with the Sieve plugin. There's a rather old thread on this list that mentions that dovecot-lda+Sieve should be able to suppress duplicates; it's not doing so automagically, though... Thanks, Adam

[Dovecot] W= fixup feature
by Arkadiusz Miskiewicz 12 Dec '08

12 Dec '08

Hi, When there are maildir mail files without W= tag in name then dovecot opens them, read data inside to calculate W= size, cache that information etc. Would be it sensible to have option where dovecot would fix names of such files? Like if no W= then after calculating size rename file to actually contain W= ? -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Do not update status on imap connections
by Adrian Reber 12 Dec '08

Does an option like "pop3_no_flag_updates = yes" also exist for imap? Is it maybe planned? Or should I just provide a patch? Adrian

[Dovecot] dovecot howto?
by Olaf Zaplinski 11 Dec '08

11 Dec '08

Hi, is there a *simple* HOWTO that explains a simple postfix+dovecot setup? Up to now, I used postfix+cyrus, worked fine. But I do not get postfix+dovecot to work. Currently, all emails go to /dev/null. What really would help me is a dovecot lmtp server. Is there any? Regards Olaf postfix main.cf: # -- delivery options # local_recipient_maps = virtual_alias_maps = btree:/etc/postfix/virtual alias_maps = btree:/etc/postfix/aliases alias_database = btree:/etc/postfix/aliases # mailbox_command = /usr/lib/dovecot/deliver mailbox_transport = dovecot postfix master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} dovecot.conf: mail_location = maildir:/home/vmail/%u namespace private { separator = '/' inbox = yes } auth default { mechanisms = cram-md5 plain verbose = yes passdb passwd-file { args = /etc/dovecot/passwd } userdb static { args = uid=vmail gid=vmail home=/home/vmail/%u } socket listen { client { # Assuming the default Postfix $queue_directory setting path = /var/spool/postfix/private/auth mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix } } }

[Dovecot] removal of all keyword.
by Matthias Rieber 11 Dec '08

11 Dec '08

Hi, how can I remove all keywords from an existing Maildir/? After reading the docs I assume this might work: 1. Stopping dovecot 2. Removing all lowercase [a-z] from the filename flags 3. Removing the dovecot-keywords file 4. Removing the dovecot.index / dovecot.index.* files Is that correct? matthias

Yes, but when Dovecot is spawned as service, the user dovecot does not log in (through PAM anyway to have pam_limits invoked), therefore I assume that limits.conf does not take effect. > Dovecot ran with a lot of proccess here, something about 800~900 imap > proccess and 5~10 login-proccess to 300~400 simultaneous users... Hmm, I do remember something similiar when the new students arrived and the number of simultaneous logins increased above some limit. I added the ulimit command to init.d.
