[Dovecot] mdbox, quota, ns, maildir quota?
by Brandon Lamb 26 Mar '11

26 Mar '11

Hello, I pasted my config below, hoping someone can point out something obvious. In my dovecot.log I am seeing: Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota I am using mysql userdb_* and passing maildir:~/maildir or mdbox:~/mdbox for mail. When its maildir its fine, I had that originally then used dsync to convert to mdbox, updated mysql entry to point to mdbox:~/mdbox and now I keept getting those quota errors. It IS possible to have mixed environment still correct? Some users can be maildir and some can be mdbox since Im using the per-user userdb options? Any hints here? I would swear this was all working on a different server I had setup but Im no longer employed there so I cant peek at the config =P Thanks for any help or tips Brandon ------------------------------------------------------------------------------- root@mail1:~# dovecot -n # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-2-amd64 x86_64 Debian wheezy/sid auth_cache_negative_ttl = 30 secs auth_cache_size = 4 k auth_cache_ttl = 30 secs auth_default_realm = greencrane.com auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 60 base_dir = /var/run/dovecot debug_log_path = /var/log/dovecot/debug.log default_client_limit = 1024 default_internal_user = mail default_login_user = mail deliver_log_format = %s from %f %$ dict/expire = mysql:/etc/dovecot/conf.d/dovecot-dict-expire.conf.ext disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 info_log_path = /var/log/dovecot/info.log last_valid_gid = 8 last_valid_uid = 8 log_path = /var/log/dovecot/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_log_format = %s login_log_format_elements = (%u) (%r) mail_access_groups = mail mail_fsync = never mail_gid = 8 mail_location = maildir:~/maildir mail_log_prefix = "%Ls <%u>: " mail_max_userip_connections = 4 mail_plugins = quota expire mail_privileged_group = mail mail_uid = 8 mailbox_idle_check_interval = 1 mins maildir_very_dirty_syncs = yes passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin/auth_socket_path = /var/run/dovecot/auth-master plugin/autocreate = Trash plugin/autocreate2 = Sent plugin/autocreate3 = Drafts plugin/autocreate4 = Spam plugin/autosubscribe = Trash plugin/autosubscribe2 = Sent plugin/autosubscribe3 = Drafts plugin/autosubscribe4 = Spam plugin/quota = maildir:User quota plugin/quota_warning = storage=95%% quota-warning 95 %u plugin/quota_warning2 = storage=80%% quota-warning 80 %u protocols = imap pop3 service auth { executable = /usr/local/libexec/dovecot/auth unix_listener auth-client { group = mail mode = 0666 user = mail } unix_listener auth-master { group = mail mode = 0666 user = mail } unix_listener auth-userdb { group = mail mode = 0666 user = mail } vsz_limit = 512 M } service dict { unix_listener dict { group = mail mode = 0666 } } service imap-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/imap-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service imap { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/imap vsz_limit = 512 M } service pop3-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/pop3-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service pop3 { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/pop3 vsz_limit = 512 M } service quota-warning { executable = script /etc/dovecot/quota-warning.sh user = mail } ssl_cert = </etc/dovecot/ssl/dovecot-cert.pem ssl_key = </etc/dovecot/ssl/dovecot-key.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } valid_chroot_dirs = /mail verbose_proctitle = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-userdb info_log_path = /var/log/dovecot/deliver.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot/deliver.log mail_fsync = optimized mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire trash autocreate postmaster_address = postmaster(a)greencrane.com quota_full_tempfail = yes rejection_reason = Your message to <%t> with subject of <%s> was automatically rejected:%n%r rejection_subject = Mailbox Full: %s sendmail_path = /usr/sbin/exim } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_id_log = * imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire imap_quota autocreate trash } protocol pop3 { mail_max_userip_connections = 2 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = yes pop3_reuse_xuidl = no pop3_save_uidl = yes pop3_uidl_format = %g }

[Dovecot] Restrict clients access during mailboxes convertion ?
by Frank Bonnet 26 Mar '11

26 Mar '11

Hello Is there a way to restrict access to Dovecot server during mailboxes convertion ? I need dovecot to be running to convert mailboxes from a format to another, but I would like to block all our LAN clients until the end of convertion. If there is no internal Dovecot mechanism I will use some firewall rule on the server. Thanks

[Dovecot] lda_mailbox_autocreate and lda_mailbox_autosubscribe
by Frank Bonnet 25 Mar '11

25 Mar '11

Hello I use real unix users on the mailhub and I would like to automate home directories creation for new users. I found lda_mailbox_autocreate and lda_mailbox_autosubscribe statements in 15-lda.conf file ( dovecot 2.0.11 ) which seem to be the right things for me :-) I use Postfix 2.8.1 with Dovecot LDA mailbox_command = /usr/local/libexec/dovecot/dovecot-lda All Mailboxes are located in /user/$USER/mail/ Does those two statements means that if a home directory does not exists it will be created at the first login of the new user ? I mean if new user "toto" has no homedir at all , dovecot will create /user/toto/mail at the very first successful connection ? Thanks a lot

[Dovecot] Issue with Dovecot v2.0 auto packages
by Stephan Bosch 25 Mar '11

25 Mar '11

Hi, Yesterday night I upgraded the automated packages built at Xi to the latest experimental Debian packages for v2.0. This unfortunately causes a problem upon upgrade. I've contacted the maintainer, so this issue should resolve itself soon. The issue manifests as follows: Setting up dovecot-imapd (2:2.0.11-0~auto+25) ... ucfr: Attempt from package dovecot-imapd to take /etc/dovecot/conf.d/20-imap.conf away from package dovecot-common ucfr: Aborting. dpkg: error processing dovecot-imapd (--configure): subprocess installed post-installation script returned error exit status 4 configured to not write apport reports The Debian maintainer split dovecot-common in various new packages and moved config files in the process. Use ucfr --purge --force dovoecot-imapd /etc/dovecot/conf.d/20-imap.conf ucfr --purge --force dovoecot-managesieved /etc/dovecot/conf.d/20-managesieve.conf ucfr --purge --force dovoecot-sieve /etc/dovecot/conf.d/90-sieve.conf to get rid of these errors as a workaround. I did this in combination with temporarily purging and removing Dovecot, but that is probably not necessary. Once you have upgraded, you will not encounter this problem again. And yes, if you are using Sieve, be sure to install the new dovecot-sieve and dovecot-managesieved packages. Regards, Stephan.

[Dovecot] Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 24 Mar '11

24 Mar '11

As of late our four node dovecot 1.2.13 cluster has been experiencing a massive number of these dotlock errors: Created dotlock file's timestamp is different than current time (1295480202 vs 1295479784): /mail/user/Maildir/dovecot-uidlist These dotlock errors correspond with very high load averages, and eventually we have to turn off all but one server to stop them from occurring. We first assumed this trend was related to the NFS storage, but we could not find a networking issue or NFS related problem to speak of. We run the mail storage on NFS which is hosted on a Centos 5.5 host, and mounted with the following options: udp,nodev,noexec,nosuid. Secondly we thought the issues were due to NTP as the time stamps vary so widely, so we rebuilt our NTP servers and found closer stratum 1 source clocks to synchronize to hoping it would alleviate the problem but the dotlock errors returned after about 12 hours. We have fcntl locking set in our configuration file, but it is our understanding from look at the source code that this file is locked with dotlock. Any help troubleshooting is appreciated.

[Dovecot] Problem with expire plugin and expunge
by Christoph Pleger 24 Mar '11

24 Mar '11

Hello, I am running dovecot 2.0.9 with expire plugin, using the sqlite backend. The following command is executed every day by cron: doveadm expunge -A mailbox Trash savedbefore 30d I started to use the expire plugin about one month ago. Since then, using "doveadm search -A mailbox Trash savedbefore <days>" with different values for <days>, I could see every day how the messages were getting older. Yesterday was the first time that the expression "savedbefore 30d" became true for the oldest messages in the Trash mailbox and these messages were actually deleted from Trash. But today, all messages that were not deleted yesterday are new to "doveadm search", that means that "doveadm search -A mailbox Trash savedbefore 0d" shows all messages from Trash, but "doveadm search -A mailbox Trash savedbefore 1d" shows no messages from Trash, though during the last month I moved messages to Trash every day. Best Regards Christoph
