[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] try to compile dovecot 2.0.11 with ssl support
by easy 24 Mar '11

24 Mar '11

Hello, I try to compile dovecot in Version 2.0.11 with ssl support on a CentOS 4.5 system. Installed packages are openssl and openssl-devel. after "./configure --with-ssl=openssl" "make" "make install"the message is: (also tried with CPPFLAGS="-I/opt/openssl/include" LDFLAGS="-L/opt/openssl/lib -ldl") Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : epoll I/O notifys .... : dnotify SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file shadow checkpassword : -pam -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite so it looks like SSL support is included, but when I start dovecot the message is: # 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-128.1.1.el5.028stab062.3ent i686 CentOS release 4.5 (Final) passdb { driver = pam } protocols = imap ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } doveconf: Error: SSL support not compiled in but ssl=yes doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/dovecot.conf: SSL support not compiled in but ssl=yes I also tried to use the source files of openssl and compile openssl by myself, but the error is the same. thanks Regards Markus

[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. Thanks, Michael # 1.2.13: /etc/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5 x86_64 CentOS release 5.5 (Final) protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 shutdown_clients: no 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_process_per_connection: no login_process_size: 128 login_processes_count: 4 login_max_processes_count: 256 login_max_connections: 386 first_valid_uid: 300 mail_location: maildir:~/Maildir mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes 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 auth default: username_format: %Ln worker_max_count: 50 passdb: driver: pam userdb: driver: passwd

Hi, I've installed sieve and managesieve(pigeonhole) on qmail and dovecot(v2.0.11). I've install sieverules on Roundcube. I can see the plugin on the webinterface, and i can add rules. But there is a problem: I've put this .qmail file on "deneme" user's home directory according to [1]. |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda -d $EXT@$USER Then I got this message on qmail log: deferral: /var/qmail/bin/preline:_line_1:_test:_too_many_arguments/ Incoming e-mail written to the disk but doesn't seen on inbox.

[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

[Dovecot] Configure Dovecot For IMAP Only?
by Carlos Mennens 23 Mar '11

23 Mar '11

I've install Dovecot 2.0.11-1 on my Linux server and all the guides and tutorials I've found on Google don't work since I'm running 2.x and it seems most guides were done with 1.x. I've opened up the configuration file /etc/dovecot/dovecot.conf & from what I can see, this is all I could come up with: protocols = imap listen = * base_dir = /var/run/dovecot login_greeting = Server ready. mail_location = maildir:~/mail I obviously want / need IMAP4 access ONLY and not POP3. I've got only 12 local Linux shell users and all authentication is done by I think PAM. My friend sent me his configuration file to see if it would work on Dovecot 2.x however I don't think it does: auth_mechanisms = plain login mail_location = maildir:~/mail passdb { driver = pam } protocols = imap service auth { unix_listener auth-client { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/certs/cert.pem ssl_key = </etc/ssl/private/key.pem userdb { driver = passwd } #protocol imap { # imap_client_workarounds = delay-newmail tb-extra-mailbox-sep #} Can anyone please tell me what I need to add to get this very basic IMAP server up and running?

[Dovecot] Mail Sync
by Scott Hughes 23 Mar '11

23 Mar '11

I am trying to sync my mail on two different servers as testing for converting our business over to a server using dovecot. I am currently running dovecot version 2.0.11 While trying to sync the messages using Thunderbird and a program named imapsync, I run into an error stating that the dovecot server does not know how to handle messages with the FORWARD flag set. Is the FORWARD flag some type of non-standard flag or is there something I need to do in dovecot to allow for this flag? Thanks

[Dovecot] Bug: Creating mbox folders
by Kelly Stephens 23 Mar '11

23 Mar '11

Hey, I had trouble this morning creating a folder to contain sub-folders. I am using the mbox format. Turns out that the .imap directory in the new folder (directory) was not being created. Anytime I tried to view a sub-folder (using Thunderbird) dovecot would dump. Once I manually created the .imap directory, it works fine. dovecot --version -> 2.0.9 dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.11-83.fc14.i686 i686 Fedora release 14 (Laughlin) listen = * mbox_write_locks = fcntl passdb { driver = pam } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } The maillog dump...

Hello, How can one assign different users different Quota? So properly? quota_rule1 = userONE:storage=1G quota_rule2 = Trash:storage=100M quota_rule3 = SPAM:ignore quota_rule4 = userTWO:storage=5M quota_rule5 = Trash:storage=50M quota_rule6 = SPAM:ignore and so on ... Right or how? -- Mit freundlichen Grüßen, Jim Knuth P.S.: Bitte senden Sie KEINE HTML-Mails! Zufallszitat: Die Geschichte wird freundlich mit mir umgehen, denn ich habe vor, sie zu schreiben.
