[Dovecot] Dovecot LDA / Deliver question
by Stacy Trippe 18 Apr '08

18 Apr '08

Problem described: I am trying to get Postfix + Dovecot + MySQL setup to work together in a virtual mail hosting platform. I am running Postfix 2.3.x, and MySQL 5.0.x. I am trying to use Dovecot's LDA for delivery to the users vmail home directory -- usually under /var/vmail/domain.com/j/jdoe for home and /var/vmail/domain.com/j/jdoe/.maildir for mail location, using MAILDIR format. However, I cannot get Dovecot's LDA to write the maildir folders/files into the right location. It wants to write in MBOX format to /var/vmail/mail/inbox instead. When I force the mail_location variable...it just uses the system 'vmail' user (uid: 1101) and 'vmail' group (gid: 1101) that I assigned for the virtual mail user. mail_location = maildir:/var/vmail/%d/%1n/%n I am not sure where to go to troubleshoot Dovecot LDA...and how to turn up/down the verbosity of debug messages (albeit now I am logging the deliver info to /var/log/dovecot-deliver.log). Does anyone know what I am missing? Can Dovecot LDA be told how to deliver mail to the users maildir folder? Here is my postfix master.cf: ... dovecot unix - n n - - pipe flags=DRhu user=vmail argv=/usr/libexec/dovecot/deliver -f ${sender} Here is my postfix main.cf (as it pertains to dovecot LDA): virtual_transport = dovecot mailbox_command = /usr/libexec/dovecot/deliver smtpd_sasl_type = dovecot dovecot_destination_recipient_limit = 1 dovecot --version 1.0.rc15 dovecot -n # /etc/dovecot.conf log_path: /var/log/dovecot.log login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: SMTP ready. login_process_size: 64 login_processes_count: 5 login_max_connections: 512 mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: passwd userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=mailsql user=mailquery password=m@1l default_pass_scheme = PLAIN-MD5 password_query = SELECT email as user, passwd AS password, concat('/var/vmail',homeDir) as userdb_home, 1101 AS userdb_uid, 1101 AS userdb_gid, concat('maildir:/var/vmail',mailDir) as userdb_mail FROM users WHERE (username = '%u' OR email = '%u' OR email = concat('%u','@domain.net')) AND status = 'A' AND type = 'M' user_query = SELECT concat('/var/vmail',homeDir) as home, 1101 AS uid, 1101 AS gid, concat('maildir:/var/vmail',mailDir) as mail FROM users WHERE username = '%u' ....

[Dovecot] Feature request
by Ruud Boon 18 Apr '08

18 Apr '08

Hi! I hope I'm using the right mailing for a feature request. I'm using dovecot on my server for a year now and I'm very happy with it. Its extremely stable and fast. Ok what is my situation why I'm asking a feature.. Users are retrieving mail using pop3 over the external ip address. When the user connects to there webmail. The webmail client (Squirrelmail) is using imap on the localhost. I would like to give some users the option to use imap over the external ip, I want to set option in my MySql backend configuration. As far as I know there isn't a possible solution on dovecot right now that's why I hope you can build a extra config parameter that gives me the possibility to allow users to retrieve email by imap by ip. So all users can do an imap request on localhost (for webmail) and some user are allowed to do an imap request over the external ip. I hope that my request is clear and I'm posting in the right group. With regards, Ruud Boon

[Dovecot] Single quote email addresses
by Guy 18 Apr '08

18 Apr '08

Hi, I've just been told that I need to make our mail server cater to accounts with single quotes. Has anyone set dovecot up to do this or know of any documentation/howto on it, assuming it's possible at all. I'm running dovecot 1.0.5 on Ubuntu 7.10 if that makes much of a difference. Thanks for any help anyone can give. Guy -- Don't just do something...sit there!

[Dovecot] dovecot and postfix virtual mailbox domains, system users
by Dave 18 Apr '08

18 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username/, there's a maildir under that area and incoming mail gets delivered by postfix to that area. In the first case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account at all. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd and the specific maillog error is this: Apr 11 23:48:17 s15298471 dovecot: pop3-login: Login: user=<user>, method=PLAIN, rip=66.139.186.37, lip=74.208.64.129, TLS Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): stat(/home/vmail//user/cur) failed: Permission denied Apr 11 23:48:17 s15298471 dovecot: POP3(user): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-04-11 23:48:17] Apr 11 23:48:17 s15298471 dovecot: POP3(user): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 I'd appreciate any pointers. I think i am close, but am not seeing it. Thanks. Dave.

[Dovecot] remove mails from shared folders
by Patrick Fischer 18 Apr '08

18 Apr '08

Hallo dovecot This is my first post on this list. I'm new to IMAP servers and i read lots of howtos. If I use the wrong term for some features please tell me the right term. I have installed dovecot under ubuntu 7.10 and it works fine. dovecot + fetchmail + postfix I would like to use shared folders the way that we have an email pool for info(a)mydomain.com user1(a)mydomain.com -> User1 user2(a)mydomain.com -> User2 user3(a)mydomain.com -> User3 info(a)mydomain.com -> Pool (look at this http://decembersoul.dyndns.org/wiki/images/c/c6/IMAP1.jpeg ) The users can see and process emails from the email pool. To process an email the user move the email from the email pool to his own inbox. This should make sure that only one user process a email. Shared folders are created by symlink. The problem is that, if a user move an email out of the email pool, the other users still can see the mail in the pool. It takes a long time to remove the mail from the pool for every user. Move TO the pool works immediatley. The user can make a "compress folder" to remove the emails but this can't be the soulution. Maybe this is a client failed (tested only with thunderbird) Best regards Patrick Fischer

[Dovecot] Minor namespace issue - inconsistent default value
by Joel Johnson 18 Apr '08

18 Apr '08

I burned some time yesterday over a documentation inconsistency. The dovecot-example.conf file shipped with dovecot (checked with 1.1rc4 and the April 3 nightly), includes an indication at the top that the commented values listed are the defaults for the settings. Line 248 of this file has the inbox setting for a private namespace which indicates that the default value for this setting is true. However, line 358 of ./srv/master/master-settings.c sets the default value of the namespace inbox variable to false. With a single private namespace (what I was setting up), one wants this value to be true, however when using multiple namespaces the default should likely remain false. I propose keeping the coded default and changing the line in the example configuration file to indicate false. Before I determined that this was the issue, I had a single namespace defined (but not as INBOX), and dovecot (both deliver and imap) created and read from a .INBOX directory under the Maildir. Thanks, Joel
