[Dovecot] Mail storage creation fails with virtual users
by Scott H. W. Snyder 30 Dec '09

30 Dec '09

So I have recently set up dovecot with a virtual users dovecot.passdb file, but when I attempt to telnet in, it fails because my virtual users don't have proper permissions to create mailboxes. I don't want to have to create actual users for each email account. Any idea as to what to do? The error that dovecot logs: dovecot: Dec 28 13:06:28 Error: IMAP(user1): mkdir_parents(/var/mail/ folders/user1) failed: Permission denied dovecot: Dec 28 13:06:28 Error: IMAP(user1): Mail storage creation failed with mail_location: mbox:/var/mail/folders/user1/:INBOX=/var/ mail/user1 dovecot: Dec 28 13:06:28 Error: child 27667 (imap) returned error 89 my [test] passdb file: user1:{PLAIN}pass1:2001:2001:User 1 Name:/var/mail/folders/user1:: mail_plugins=cmusieve user2:{PLAIN}pass2:2002:2002:User 2 Name:/var/mail/folders/user2:: mail_plugins=cmusieve user3:{PLAIN}pass3:2003:2003:User 3 Name:/var/mail/folders/user3:: mail_plugins=cmusieve user4:{PLAIN}pass4:2004:2004:User 4 Name:/var/mail/folders/user4:: mail_plugins=cmusieve Conf settings: -bash-3.2# /usr/local/sbin/dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /usr/local/var/run/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.info.log protocols: imap listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run//login login_executable: /usr/local/libexec/dovecot/imap-login login_greeting: Hi buddy, have an account ? max_mail_processes: 2048 verbose_proctitle: yes first_valid_uid: 1000 last_valid_uid: 5000 mail_location: mbox:/var/mail/folders/%u/:INBOX=/var/mail/%u mail_debug: yes mbox_read_locks: dotlock fcntl auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb userdb: driver: passwd-file args: /usr/local/etc/dovecot.passdb socket: type: listen master: path: /usr/local/var/run/dovecot-auth-master mode: 432 user: dovecot group: mail

[Dovecot] Upgrade 1.0->1.2 dbox mysql
by Bradley Giesbrecht 29 Dec '09

Hi, I just upgraded to from dovecot v1.1.15 to v1.2.9 so I can use dovecot- sieve. Most everything seems to work but my webmail (roundcube) clients are not seeing their subscribed folders.

[Dovecot] Install fails when libdir and libexecdir are the same directory
by River Tarnell 29 Dec '09

29 Dec '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using Dovecot 1.2.9. I configured it like this: % ./configure --prefix=/opt/rt --libdir=/opt/rt/lib \ --libexecdir=/opt/rt/lib [other args...] It compiled fine, but failed to install, because it tries to install a directory called <libdir>/dovecot/imap, and a file called <libexecdir>/dovecat/imap, which obviously doesn't work when libdir and libexecdir are the same directory: gmake[5]: Entering directory `/home/river/hp-pkg/mail/dovecot/work/dovecot-1.2.9/src/plugins/imap-acl' gmake[5]: Nothing to be done for `install-exec-am'. test -z "/opt/rt/lib/dovecot/imap" || /opt/rt/bin/gmkdir -p "/home/river/hp-pkg/mail/dovecot/install/opt/rt/lib/dovecot/imap" /opt/rt/bin/gmkdir: cannot create directory `/home/river/hp-pkg/mail/dovecot/install/opt/rt/lib/dovecot/imap': File exists gmake[5]: *** [install-imap_moduleLTLIBRARIES] Error 1 As a workaround I used --libexecdir=/opt/rt/lib/dovecot/libexec, but perhaps one of the conflicting files could be moved or renamed.

[Dovecot] multiple attribute templates?
by Mariano Absatz 29 Dec '09

29 Dec '09

Hi, I've been using an attribute template for some time without any problems. My accounts are on an LDAP server and I have an attribute maildropPath which is the maildir path for the user relative to /home/vmail That is, user "mabsatz(a)example.org" has, in attribute maildropPath the string "example.org/mabsatz", meaning that the maildir is in /home/vmail/example.org/mabsatz This is configured like this (taken from http://wiki.dovecot.org/AuthDatabase/LDAP/Userdb) user_attrs = maildropPath=mail=maildir:/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$ and it works OK. Now I want to start using sieve and, since all accounts are virtual, I want to use a subdirectory "sieve" within the maildir to hold the scripts, so I need (I think) a userdb home to point to the same path... being a monkey I tried to imitate (or rather, extend) the previous configuration like this: user_attrs = maildropPath=mail=maildir:/home/vmail/%$,maildropPath=home=/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$,maildropPath=userdb_home=/home/vmail/%$ Alas... this didn't work... that is, apparently, the "home" attribute works OK (I got my scripts on the /home/vmail/example.org/mabsatz/sieve directory), but the "mail" attribute got lost and mail is being delivered to /home/vmail/mabsatz. Is there a way to use more than one attribute template AND that both use the same LDAP attribute? Otherwise, can someone think of a better way to do what I'm trying to do? I'm using dovecot 1.1.11 from the standard ubuntu 9.04 package (dovecot-imapd_1.1.11-0ubuntu4.1). -- Mariano Absatz - "El Baby" el.baby(a)gmail.com www.clueless.com.ar -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Real programmers use: cat > a.out http://xkcd.com/378/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- * TagZilla 0.066 * http://tagzilla.mozdev.org

[Dovecot] Deliver EX_TEMPFAIL's without giving any information
by Denis Khromov 29 Dec '09

29 Dec '09

Hi all. I've had a hard time trying to find out why deliver isn't working after I've updated dovecot from v1.11 to v1.2.8. It just gave me EX_TEMPFAIL without any info in the logs. My deliver was setuid-root. Once I've made a simple shell wrapper script for the deliver executable which saves deliver's stdout+stderr, I've found the reason: /usr/local/libexec/dovecot/deliver must not be both world-executable and setuid-root. This allows root exploits. See http://wiki.dovecot.org/LDA#multipleuids Did a 'chmod o-x deliver' and fixed groups/owners and now everything works as it should. I think this error message should go to log files, not just to stdout/stderr. And it's worth to describe this behaviour in the Wiki. Cheers, Denis

[Dovecot] dovecot -n output of (default) is confusing me
by john.blue＠cox.net 29 Dec '09

29 Dec '09

Hello, I'm new to dovecot and I've been taking my time examining what makes dovecot work. If I have imap and pop3 listed as protocols, dovecot -n outputs: mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 I don't understand why imap is listed twice once as (default), and the other without (default). As a secondary question, why would you want a default of imap as opposed to pop3? Thanks. John

[Dovecot] Log rotation?
by Beto Moreno 29 Dec '09

29 Dec '09

Hi people. I had read dovecot logging info, they say something about using log rotation to help us rotate our log, with this setup: # dovecot SIGUSR1: Re-opens the log files. /var/log/dovecot*.log { missingok notifempty delaycompress sharedscripts postrotate /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true endscript } Well, my question is simple, Do we need to restart the service each time logrotation runs? In my case, is wrong this? var/log/dovecot*.log { weekly rotate 8 notifempty missingok copytruncate create 600 root start 0 } I have 2 dovecot logs: dovecot-info.log dovecot.log dovecot-info.log is the biggest, 5MB by week, is to much? Do I have to change our log rotation to "daily"? Centos 5.4 updated, dovecot 1.0.7-7.el5, thanks!!!

[Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 29 Dec '09

29 Dec '09

Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm overriding "update_flags":void my_mail_update_flags(struct mail *_mail, enum modify_type modify_type, enum mail_flags flags)For this email which is having its flags updated, I need to retrieve the physical filename of the message. I see where using:mail_get_special(_mail, MAIL_FETCH_UIDL_FILE_NAME, &fname);...I can retrieve part of the filename, but without the ":2" and the flags part.Is there a method I can use to get the whole filename (without having to reassemble it myself). I've looked around, and I'm guessing it exists, but I don't see it offhand.Thanks,...Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040 This message is intended solely for the individual(s) to whom it is addressed.
