Released Pigeonhole v0.4.19.rc1 for Dovecot v2.2.31.rc1.
by Stephan Bosch 22 Jun '17

22 Jun '17

Hello Dovecot users, This small release is mainly about adjusting to changes in the Dovecot API. There is one significant fix. Changelog v0.4.19: * This release adjusts Pigeonhole to several changes in the Dovecot API, making it depend on Dovecot v2.2.31. Previous versions of Pigeonhole will produce compile warnings with the recent Dovecot releases (but still work ok). - Fixed bug in handling of implicit keep in some cases. Implicit side-effects, such as assigned flags, were not always applied correctly. This is in essence a very old bug, but it was exposed by recent changes. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.19… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.19… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

+vnd.dovecot.duplicate for Bogofilter duplication shortcomings
by Luescher Claude 21 Jun '17

21 Jun '17

Hello, Sorry for a bit offtopic but it seems the bogofilter community is just as dead as dspam is. I trying to switch from DSPAM to bogofilter on a server where if I turn bogofilter on I run into the following issue: Certain users have sender and recipient bcc maps setup in postfix. This is for forwarding copy of an email to other address for example: Incoming lclude(a)company.com -> info(a)company.com Outgoing lclude(a)company.com -> info(a)company.com This way whatever lcalude sends or receives a copy will be sent to the info mailbox. When bogofilter is enabled the bcc recipient (info) receives a dupe of every email. Did anybody run into this? virtual_destination_recipient_limit = 1 dspam_destination_recipient_limit = 1 was a working fix for me for the old system, however bogofilter_destination_recipient_limit = 1 does not work in this case so if this issue is not possible to fix by configuration an alternate solution like making dovecot delete duplicate messages by message ID would be a viable option. I have +vnd.dovecot.duplicate plugin enabled but it seems to be ineffective. Any other tips for a workaround? Thank you. Claude

dovecot & cap_net_admin capability
by Michal Hlavinka 21 Jun '17

21 Jun '17

Hi, we've seen SELinux reports from our users that dovecot tried to use something that needs CAP_NET_ADMIN capability. Before enabling it, we would like to know where it originated from. I've checked the sources, but was not able to find anything that would require this capability. Do you know for what it is used? CAP_NET_ADMIN Perform various network-related operations: * interface configuration; * administration of IP firewall, masquerading, and accounting; * modify routing tables; * bind to any address for transparent proxying "IP_TRANSPARENT"; * set type-of-service (TOS) "IP_TOS" * clear driver statistics; * set promiscuous mode; * enabling multicasting; * use setsockopt(2) to set the following socket options: SO_DEBUG, SO_MARK, SO_PRIORITY (for a priority outside the range 0 to 6),SO_RCVBUFFORCE, and SO_SNDBUFFORCE Cheers, Michal Hlavinka

Thunderbird "Empty Trash" causes inconsistent IMAP session state?
by awl1 20 Jun '17

20 Jun '17

All, having successfully compiled and set up Dovecot 2.2.29.1 on my Thecus NAS as a newbie without any further hassle, and already imported an external mail archive of ~15 GB into a lz4-compressed mdbox (with impressive performance on the old Intel Atom CPU!), I stumbled into a minor, but reproducible issue that might well be already known, but I haven't managed to find any pointers through Google search: When I *manually empty the Trash folder from Thunderbird* (52.1.1, regardless of Windows or Linux client) by right-clicking on a non-empty Trash folder and then selecting "Empty trash", Dovecot produces the following log message, and I need to restart Thunderbird client in order to properly refresh its folder status: May 30 23:42:04 imap(xxx(a)xxx.org): Info: *IMAP session state is inconsistent, please relogin.* in=405 out=3114 Is this behaviour and message intended, or did I indeed run into a bug here? Many thanks & best regards Andreas

Hey, Is there a way to show other users quota under shared namespace? Right now when I try to "a getquotaroot user/other.user" I get "NO Not showing other users' quota" Dovecot version 2.2.27 Relevant part of the config: namespace user { list = children location = maildir:%%h/Maildir:LAYOUT=fs:DIRNAME=iiuuuuiiiuuu:INDEXPVT=%h/shared/%%n prefix = user/%%n/ separator = / subscriptions = no type = shared } Kristjan

Have you checked whether the dovecot user can traverse all the way from / to /u2/usermail/luser/ > I've (rm ~/mail/.subscriptions && touch ~/mail/.subscriptions) to flush any > subscriptions file issues.

Dovecot does have chroot-ing stuff that might impede symlink following: https://wiki.dovecot.org/Chrooting > Other data: there are fs quotas on / but not /u2. That shouldn't matter, but > I will concede that I'm not a little ignorant about such things. It seems you have more basic file access problems. > How might I go about further debugging this?

Nothing with verbose logging (set mail_debug = yes)? Try the simple case ln -s /u2/usermail/luser/OLD_INBOX/INBOX_2016_01_to_08 ~luser/mail/testbox then $ telnet localhost 10143 x0 login luser *** x1 SELECT testbox What do you get here and in your logs? If this doesn't produce any usable diagnostics, I would pull out the heavy duty process trace tool and trace the imap process to figure out what it's really doing and where it's failing.

After done an update to dovecot-2.2.30.2 my connection is broken since days. all what I try every time the same error: Jun 15 00:02:18 auth: Error: auth: environment corrupt; missing value for DOVECOT_ Jun 15 00:02:18 auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address Jun 15 00:02:18 master: Error: service(auth): command startup failed, throttling for 2 secs I try this: # doveadm -Dv auth test -x service=imap theusername mypassword output: Debug: Loading modules from directory: /usr/local/lib/dovecot Debug: Module loaded: /usr/local/lib/dovecot/lib20_virtual_plugin.so Debug: Loading modules from directory: /usr/local/lib/dovecot/doveadm Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/local/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so: Undefined symbol "acl_user_module" (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/local/lib/dovecot/doveadm/lib10_doveadm_expire_plugin.so: Undefined symbol "expire_set_lookup" (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_quota_plugin, because dlopen() failed: /usr/local/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so: Undefined symbol "quota_user_module" (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/local/lib/dovecot/doveadm/lib20_doveadm_fts_plugin.so: Undefined symbol "fts_filter_filter" (this is usually intentional, so just ignore this message) Debug: Skipping module doveadm_mail_crypt_plugin, because dlopen() failed: /usr/local/lib/dovecot/doveadm/libdoveadm_mail_crypt_plugin.so: Undefined symbol "mail_crypt_user_get_public_key" (this is usually intentional, so just ignore this message) Error: Timeout waiting for handshake from auth server. my pid=63521, input bytes=0 Fatal: Couldn't connect to auth socket dlopen() failed, Undefined symbols ... Is this a bug? How do I check what is going wrong with this auth socket error? 2nd) I'm using dovecot.conf protocols = imap lmtp !include conf.d/*.conf 10-auth.conf , 10-master.conf, auth-passwdfile.conf.ext, 10-ssl.conf and 10-logging.conf (all logs are on) All others, form the 29 configuration files, I haven't touch. It has worked, before I have done the update. What has changed? For what in the *.conf should I locking for? Thanks a lot.
