[Dovecot] Released Pigeonhole v0.2.5 for Dovecot v2.0.16
by Stephan Bosch 19 Nov '11

19 Nov '11

Hello Dovecot users, Before I move active development of Pigeonhole to Dovecot v2.1, I first release all the pending bug fixes and small improvements. Changelog v0.2.5: + Sieve vacation extension: made discard message for implicit delivery more verbose - The sieve-test tool: mixed up original and final envelope recipient in implementation of command line arguments. - Sieve vacation extension: resolved FIXME regarding the use of variables in the :handle argument. Variables are now handled correctly. - Sieve body extension: fixed handling of :content "message/rfc822". This now yields the headers of the embedded message as required by the specification. Handling of :content "multipart" remains to be fixed. - LDA Sieve plugin: fixed problem with recipient_delimiter configuration. Now it falls back to global recipient_delimiter setting if plugin/recipient_delimiter is not set. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.5.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] CCing outbound IMAP mail?
by Dave Stevens 18 Nov '11

18 Nov '11

For some users on my site I'd like to be able to CC a particular user on all outgoing IMAP mails. Incoming I can do but don't see how to do outgoing. Ideas?

[Dovecot] Mail_quota plugin and LDAP on Dovecot 1.2
by Victor 18 Nov '11

18 Nov '11

Hi, I'm new in this List, but I have 6 years using Dovecot on my debian from etch,lenny and now squeeze Package: dovecot-imapd Version: 1:1.2.15-4 Tags: squeeze -- System Information: Debian Release: 6.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/24 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages dovecot-imapd depends on: ii dovecot-common 1:1.2.15-4 secure mail server that supports m ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libldap-2.4-2 2.4.23-7 OpenLDAP libraries ii libssl0.9.8 0.9.8o-4 SSL shared libraries the quota_imap plugin not working when I use against MailquotaSize Attribute of LDAP users. this setup works perfectly on lenny and dovecot-imapd 1:1.0.15-2.3 but on squeeze dovecot-imad 1:1.2.15-7 doesn't work, the service is up, but The quota does not display. In logs nothing happens the configuration in dovecot.conf below protocol imap { mail_plugins = quota imap_quota } protocol lda { mail_plugins = quota } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } the configuration in dovecot-ldap.conf below uris = ldap://server-ldap.com.ve auth_bind = yes ldap_version = 3 base = dc=dominio,dc=com,dc=uk deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota=dirsize:storage user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) This is the same configuration in the 6 last years. So, I would really appreciate if give me a hand which are more than 15000 Users who administered easily taking the quota in the LDAP attribute. and I want to keep the scheme.

by David Mehler 18 Nov '11

18 Nov '11

Hello, I'm using Dovecot v2 and am atempting to get webmail going. I'm trying to set up imap so that port 993 only is listening on the external interface, for both ipv4 and ipv6, but that on localhost only again for ipv4 and ipv6 unencrypted port 143 is active. I've tried various combinations but keep getting an error invalid number. I've googled and not come up with the missing point. Thanks. Dave.

[Dovecot] dsync problems
by Micah Anderson 17 Nov '11

17 Nov '11

When a user renames their username, I am using dsync to copy their mail over to the new username's mail location[0]. Some of the dsyncs are failing with errors that I dont know how to work with, for example: dsync(<username>): Error: Trying to open a non-listed mailbox with guid=41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: msg iteration failed: Couldn't open mailbox 41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=41fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=42fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=43fcd40303c8a64e432300007ef44c7a dsync(<username>): Error: Trying to open a non-listed mailbox with guid=44fcd40303c8a64e432300007ef44c7a ERROR: dsync failed, exit code: 256 The errors cause a non-zero exit code from dsync, which causes my rename script to bail out. What are these errors, and how can I fix them? Thanks, micah 0. Why use dsync instead of a simple mv operation? This seems to be necessary for two corner cases: 1. dovecot creates the new mailbox automatically when the user logs in or receives a mail, so if the user changes their mail and logs in or receives an email before the move has been done, then the mailbox is created and then a move command will fail. 2. If there has been new mail created under the new name, we can't just simply remove the stuff that is automatically created there and replace it with the old things because we could potentially be removing mail that has been delivered in the mean time. I'd be really interested if people had suggestions for a better mechanism, or perhaps a way to have dovecot not create the new mail location automatically. --

[Dovecot] 2.1: virtual plugin and lsub
by e-frog 17 Nov '11

17 Nov '11

Hi Timo, I'm using the virtual plugin and have 2 mailboxes configured in the "virtual" namespace (dovecot -n attached). Using lsub with dovecot 2.0.15 leads to the following result: 1 lsub "" "virtual/*" * LSUB () "/" "virtual/Lists" * LSUB () "/" "virtual/unread" 1 OK Lsub completed. However with dovecot 2.1 (latest hg as of today) and the same config there is a 3rd mailbox "virtual" listed which doesn't exist: 1 lsub "" "virtual/*" * LSUB () "/" "virtual" * LSUB () "/" "virtual/Lists" * LSUB () "/" "virtual/unread" 1 OK Lsub completed. Thunderbird shows the "virtual" mailbox as selectable and not grayed out as with 2.0.15. Clicking on that mailbox gives an error message "Mailbox doesn't exist: virtual". Thanks, e-frog

[Dovecot] Performance-Tuning
by Peer Heinlein 17 Nov '11

17 Nov '11

Hi, I have > 11 TB hard used Mailstorage, saved als maildir in ext3 on HP EVA. I always wanted to make some mesurements about several influences to the performance (switch to ext4, switch to mdbox), but I never had enough time to do that. At the moment I *need* more speed, we have too much waitI/O on the system and I already used all other performance and tuning-tricks (separated cache, noatime, fsync and all that stuff). I have to change my setup, maybe somebody else here have hard facts: *) Is ext4 faster? How much faster? *) Is it faster because of the ext4 kernel-module (which can be used on ext3 to) or because of the ext4 filesystem layout? *) Is mdbox really faster? I'd like to have mdbox to have better performance in running my backup-processes. But does it bring some performance boosts to? Thanks for any hints an tricks, Peer -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030/405051-42 Fax: 030/405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Port variable in LMTP userdb lookups?
by Mark Zealey 17 Nov '11

17 Nov '11

Hi all, I'm currently changing some systems to use the redirector service, which means that to get local deliveries going I need to get lmtp set up so it can be redirected as well. This is working fine, however we have a number of different ports running on our servers depending on which brand a customer is using. When the time comes to do the user look up, we use (port, user, domain) to do a unique database lookup which works fine for everything (proxied pop, imap, lmtp & straight pop, imap) but not straight lmtp - perhaps because it doesn't have a 2-stage login process unlike the pop/imap protocols. Looking at the SQL query we are issuing, the %a port variable is set to 0 even though the connection is coming in from TCP. Is there a way to change this? We are running dovecot 2.0.12 however looking through the changelogs I can't see this would be fixed in the newest version. Thanks, Mark
