[Dovecot] nfs_flush errors
by Hans Wunsch 04 Aug '08

04 Aug '08

I'm looking for some help with an nfs error that is filling our logs. I get a constant stream of these messages: Jul 8 10:47:08 servername dovecot: [ID 107833 mail.error] IMAP(username): nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy I have two dovecot IMAP servers. All mailboxes are NFS mounted. The INBOX is /var/mail and the rest are in /home/<user>/mail. It looks like work was done on this back in January: http://www.dovecot.org/list/dovecot-cvs/2008-January/010638.html And again in February: http://hg.dovecot.org/dovecot-1.1/rev/258477a3f1e7 Was a there another fix that I missed or is anybody else is still seeing the same issue? Thanks, Hans

[Dovecot] Problem: delivery with mode 600 into shared folder
by seriv＠parkheights.dyndns.org 04 Aug '08

04 Aug '08

Hi, I have a problem, delivery called from /etc/aliases file by pipe delivers with mode 0600. I need system users with shared mail folders (Maildir format). When I changed alias to pipe to shell wrapper with mode 002 set in it, nothing changed. MTA is sendmail, OS Solaris, and dovecot version 1.1.1. Can somebody help? Here are dovecot settings: --- /opt/dovecot11/sbin/dovecot -n # 1.1.1: /opt/dovecot11/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log login_dir: /var/run/dovecot//login login_executable: /opt/dovecot11/libexec/amd64/dovecot/imap-login max_mail_processes: 128 mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index mail_debug: yes auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: imap userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: daemon group: other plugin: sieve: /opt/dovecot11/sieve-scripts/folders.sieve --- And this is the alias to pipe: --- grep deliver /etc/aliases listuser(a)domain.com: "|/opt/dovecot11/libexec/dovecot/deliver -d listuser" -- Sergey Ivanov.

[Dovecot] Recieving e-mail is not updating quota
by M. Rodrigo Monteiro 04 Aug '08

04 Aug '08

Hello again. When I send e-mail locally from userX@mydomain to userY@mydomain the quota in userY@mydomain isn't updated with the new message, but the message arrives fine. It's not a userX problem, because it's equal if it's userY sending userX. When I save an message, the quota is updated. Or when the userX sends the e-mail, his quota is updated too. The problem is that the quota don't update when a new message arrives. What could it be? Now I empty the mailbox of the userY, and the maildirsize is like this: 16777216S 0 0 1151862 1 2837616 1 2838683 1 5674797 2 -5674797 -2 -5674797 -2 1151862 1 -1151862 -1 -1151862 -1 The user quota from ldap is 16MB. In the user dir, the size is 452K # du -kh . --max-depth=0 452K . Now, I send an e-mail about 900k from userX to userY, and the quota display still 0M, but the user dir is 1,6M # du -kh . --max-depth=0 1,6M .

[Dovecot] namespaces at v1.0.15
by Evaggelos Balaskas 04 Aug '08

04 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, i need to create a public maildir folder for virtual users so i did this: dovecot-1.0.15: namespace public { prefix = public/ separator = / location = maildir:/var/mail/shared:INDEX=/var/mail/shared/%u/index/:CONTROL=/var/mail/shared/%u/control/ } namespace private { separator = / prefix = inbox = yes } umask = 007 and everything works fine, but ... when one user reads an email from the public folder then the status (flag read) changes to all users. How i can fix this? How every virtual user (same uid.gid) can have its own index (perhaps?)

[Dovecot] 1.1.2 segfaults when using passdb passwd and md5 mechanism
by Miguel Filho 04 Aug '08

04 Aug '08

Setting passdb to passwd and enabling cram-md5 or digest-md5 makes dovecot crash. The documentation says that I can use md5 with passwd. I had to use strace to figure it, because dovecot segfaults and doesn't log the error.

[Dovecot] Dovecot doesn't read users and passwords from config files
by Marco Fioretti 04 Aug '08

04 Aug '08

Greetings, I am setting up Dovecot 1.0.15 on my home Fedora Core 8 pc ONLY to access my mail archives across several mail clients. No access from the internet is possible or needed here. I cannot log in with any client, the login always fails. The reason, as I understand, is that when dovecot starts it doesn't read any user name from the userdb file, so when I try to login it doesn't recognize my name and so doesn't even try to verify the password: maillog excerpt: Aug 3 00:06:11 polaris dovecot: Dovecot v1.0.15 starting up Aug 3 00:06:11 polaris dovecot: auth(default): passwd-file /etc/local_dovecot_passwords: Read 0 users Aug 3 00:06:11 polaris dovecot: auth(default): passwd-file /etc/local_dovecot_users: Read 0 users Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5150 Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5148 Aug 3 00:06:12 polaris dovecot: auth(default): new auth connection: pid=5149 Aug 3 00:06:26 polaris dovecot: auth(default): client in: AUTH#0111#011PLAIN#011service=IMAP#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011resp=AG1hcmNvAGdpZ2V0dG8= Aug 3 00:06:26 polaris dovecot: auth(default): passwd-file(marco,127.0.0.1): lookup: user=marco file=/etc/local_dovecot_passwords Aug 3 00:06:26 polaris dovecot: auth(default): passwd-file(marco,127.0.0.1): unknown user Aug 3 00:06:27 polaris dovecot: auth(default): client out: FAIL#0111#011user=marco Aug 3 00:06:27 polaris dovecot: imap-login: Disconnected: user=<marco>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured the dovecot.conf file, purged by comments, is below.

[Dovecot] Server power loss and "Dovecot is already running with PID xxx"
by Pekka Savola 04 Aug '08

04 Aug '08

Hi, I'm running Dovecot 1.0.7 (with various patches) on CentOS 5.2. The server has suffered a couple of power loss events. Dovecot is run as a standalone server. The problem is that dovecot refuses to start up at boot because the PID file from before the power loss is left behind. The message is as follows: $ /sbin/service dovecot start Starting Dovecot Imap: Error: Dovecot is already running with PID 10825 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] (Note: there is nothing wrong in the configuration file so the error message is somewhat misleading.) I looked at the release notes of 1.0.xx releases and they didn't mention this. Is this already a known problem? Should the start-up logic be made more robust (e.g. check whether a process corresponding to the PID actually exists)? -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."

[Dovecot] related, but off-topic: how to allow users to change password?
by Sahil Tandon 04 Aug '08

My dovecot is currently configured to authenticate vs. a userdb/passdb passwd-file that contains, for each user: username:passhash:5000:5000::/path/to/home::userdb_mail=/path/to/maildir Is it possible to let users authenticate and change their passwords? There are some webmail client add-ons that allow such things if users are system accounts or in a MySQL/LDAP db. Does anyone else use passdb/userdb passwd-files like above and have a method for allowing users to change their passwords from the web? Sorry for the slightly off-topic question, but hoping another Dovecot admin has solved this problem. Preference is to not to be tied to any particular webmail client just for this change password feature.
