https://dovecot.org/releases/2.2/rc/dovecot-2.2.31.rc1.tar.gz https://dovecot.org/releases/2.2/rc/dovecot-2.2.31.rc1.tar.gz.sig Unless new bugs are found, this will be the final v2.2.31 release, which will be released on Monday. * LMTP: Removed "(Dovecot)" from added Received headers. Some installations want to hide it, and there's not really any good reason for anyone to have it. + Add ssl_alt_cert and ssl_alt_key settings to add support for having both RSA and ECDSA certificates. + pop3-migration plugin: Strip trailing whitespace from headers when matching mails between IMAP and POP3. This helps with migrations from Zimbra. + acl: Add acl_globals_only setting to disable looking up per-mailbox dovecot-acl files. + Parse invalid message addresses better. This mainly affects the generated IMAP ENVELOPE replies. - v2.2.30 wasn't fixing corrupted dovecot.index.cache files properly. It could have deleted wrong mail's cache or assert-crashed. - v2.2.30 mail-crypt-acl plugin was assert-crashing - v2.2.30 welcome plugin wasn't working - Various fixes to handling mailbox listing. Especially related to handling nonexistent autocreated/autosubscribed mailboxes and ACLs. - Global ACL file was parsed as if it was local ACL file. This caused some of the ACL rule interactions to not work exactly as intended. - auth: forward_* fields didn't work properly: Only the first forward field was working, and only if the first passdb lookup succeeded. - Using mail_sort_max_read_count sometimes caused "Broken sort-* indexes, resetting" errors. - Using mail_sort_max_read_count may have caused very high CPU usage. - Message address parsing could have crashed on invalid input. - imapc_features=fetch-headers wasn't always working correctly and caused the full header to be fetched. - imapc: Various bugfixes related to connection failure handling. - quota=imapc sent unnecessary FETCH RFC822.SIZE to server when expunging mails. - quota=count: quota_warning = -storage=.. was never executed - quota=count: Add support for "ns" parameter - dsync: Fix incremental syncing for mails that don't have Date or Message-ID headers. - imap: Fix hang when client sends pipelined SEARCH + EXPUNGE/CLOSE/LOGOUT. - oauth2: Token validation didn't accept empty server responses. - imap: NOTIFY command has been almost completely broken since the beginning. I guess nobody has been trying to use it.

Issue with dsync server - copy transaction record copying to wrong destination mailbox.
by Ivan Warren 22 Jun '17

22 Jun '17

Hello all, I am encountering the following issue : I have 2 dovecot servers with 2 way replication. Everything works fine except for one specific issue : When my MUA (thunderbird) filters (junk & manual) refile a mail from my inbox, I then sometimes find multiple copies of the original message in the destination folder. I have seen the following log entries which make me think (but I'm new to this) that there could be an issue with the processing of the COPY transaction record during DSYNC : * TB Marking msg as Junk Jun 22 20:36:14 db04 dovecot: imap(ivan): flag_change: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * TB Copies msg to Junk Mailbox Jun 22 20:36:14 db04 dovecot: imap(ivan): copy from INBOX: box=Junk, uid=32059, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * TB expunges mail from INBOX Jun 22 20:36:14 db04 dovecot: imap(ivan): expunge: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Local server receives transaction from remote server and saves message again to INBOX Jun 22 20:36:16 db04 dovecot: dsync-local(ivan): save: box=INBOX, uid=502903, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Remote server copies message from INBOX to INBOX <<<<<<<<<<<<<< That's my issue Jun 22 20:36:16 db04 dovecot: doveadm: Error: dsync-remote(ivan): Info: copy from INBOX: box=INBOX, uid=502903, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 * Remote server expunges msg copy Jun 22 20:36:16 db04 dovecot: doveadm: Error: dsync-remote(ivan): Info: expunge: box=INBOX, uid=502902, msgid=<RF7w0iVHwvOBtpFW7y7eTF3jazYxJeuFC9JvB9xsjnk.gI5bQ0w8OtJJT7-T4krQTG3XkEqb5Hti..., size=9942 Is this a known issue (I may not have looked deep enough..) ? Is more information needed ? (note again that for me dovecot is working perfectly fine except for that little issue). (Version is 2.2.27 from Debian stretch) Thanks, --Ivan

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
