Dear Aki thank you! With version 2.3.11 of dovecot it works fine.

We don't really support 2.2.22 since it was released several years ago. Please try to reproduce this issue with 2.2.36 or 2.3.11. You can find packages for 2.3.11 from https://repo.dovecot.org Aki

Default sieve mark seen?
by ＠lbutlr 22 Sep '20

22 Sep '20

I have the following in my default.sieve file: require "fileinto"; if header :contains "X-spam-flag" "YES" { require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables", "imap4flags"]; setflag "\\Seen"; fileinto "Junk"; } This is largely unchanged, except that I added imap4flags and set flag "\\Seen"; recently. The messages still get filed into the user's Junk folder, but they are still marked as unread. I also have imapsieve_mailbox3_name = Archive imapsieve_mailbox3_causes = COPY imapsieve_mailbox3_before = file:/usr/lib/dovecot/sieve/mark-read.sieve # cat /usr/lib/dovecot/sieve/mark-read.sieve require ["imap4flags"]; setflag "\\seen"; Which works fine. How do I fix this? -- "The female of all species are most dangerous when they appear to retreat." - Don Marquis

Dovecot virtual folders usage: seen in Tbird client if subscribed, treated as _real_ folders -- and archived to local/offline storage? How to prevent?
by PGNet Dev 22 Sep '20

22 Sep '20

i run a dovecot v2.3.10 server. config includes virtual folders, dovecot.conf mail_plugins = virtual mail_location = maildir:/data/mail/%d/%n/Maildir:LAYOUT=fs:UTF-8 imap_capability = +SPECIAL-USE namespace inbox { inbox = yes type = private separator = / prefix = hidden = no list = yes subscriptions = yes ... mailbox virtual/All { special_use = \All auto = no comment = All } mailbox virtual/Flagged { special_use = \Flagged auto = no comment = Flagged } ... } namespace virtual { prefix = virtual/ separator = / location = virtual:/data/mail/virtual:INDEX=MEMORY hidden = no list = yes subscriptions = yes } and /data/mail/virtual/All/dovecot-virtual * -Trash -Trash/* All /data/mail/virtual/Flagged/dovecot-virtual * Flagged in Thunderbird client, without subscribing to the virtula folders, per account, they're undisplayed/inaccessible. if I select 'subscriptions', virtual All [X] Flagged [X] I see the aggregated/flagged messages. When I sync for offline usage, TBird copies messages to local storage for offline use, as expected but it ALSO *copies* all the 'virtual' messages to dirs in the local store cd ImapMail/user001-maildir tree -L 1 -d virtual.sbd/ virtual.sbd/ ├── All <========== └── Flagged <========== **DUPLICATING** messages stored in BOTH the parent/original dirs, AND a second copy in the Virtual dir. What needs to be done in order to see/use the subscribed Virtual folders in TBird enable Offline Sync/Storage & PREVENT the duplication and local storage of the 'virtual' mail instances ?

extra fields question
by joao＠7lan.net 21 Sep '20

21 Sep '20

Hi, I'm trying to configure the use of plugins per user in dovecot, more specifically, fts and fts_solr. It happen to have other necessary plugins per protocol, for example "imap_quota" which would be specifically for the imap protocol and which does not apply for the lmtp protocol. For this I need to specify that for the imap protocol I have: protocol imap { mail_plugins = quota imap_quota zlib imap_sieve mail_log notify } and for the lmtp protocol I have: protocol lmtp { mail_plugins = quota zlib fts fts_solr sieve } I did it according to the "extra fields" documentation and separated the name and key with /. My queries are correct but are not being applied to dovecot. Then in the case when the user has fts fts_solr he returns: procotol/imap/mail_plugins -> quota imap_quota zlib imap_sieve mail_log notify fts fts_solr procotol/lmtp/mail_plugins -> quota zlib sieve fts fts_solr but it does not work. Doing it for "mail_plugins" (without accessing config levels) extra fields works, but it also enable some plugins that are not compatible with some protocols. I thought about separating an instance of dovecot lmtp on the same server, but I would like a more direct configuration in the same instance. Does anyone have experience with this? Thanks in advance.

migrations from 2.2.36

Hi I started migrations dovecot cluster from 2.2.36.4 (debian) to 2.3.8 (cetos8) .I read https://wiki2.dovecot.org/Upgrading/2.3 In 10-director.conf I must disable director_doveadm_port like: #director_doveadm_port = 2424 and add: ..... service doveadm { inet_listener { port = 2424 } } Is this correct ? the rest of the contents of the file service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0666 } unix_listener director-userdb { mode = 0600 } inet_listener { port = 9090 } } service imap-login { executable = imap-login director } service pop3-login { executable = pop3-login director } # Enable director for LMTP proxying: protocol lmtp { auth_socket_path = director-userdb } service managesieve-login { executable = managesieve-login director } protocol doveadm { auth_socket_path=director-userdb }

auth_passdb_request_finished request fires twice on IMAP login
by Eirik Rye 21 Sep '20

21 Sep '20

Hi, Dovecot v2.3.11.3 (502c39af9) auth_passdb_request_finished appears to fire twice for an IMAP login using a Redis passdb. auth_request_finished only fires once. In the debug log below, the line "Finished passdb lookup" appears to be logged twice (once by "auth" and once by "auth-worker"). However, the actual passdb lookup against Redis is only performed once. This is confirmed by monitoring queries made against Redis.

auth_passdb_request_finished request fires twice on IMAP login
by Eirik Rye 19 Sep '20

19 Sep '20

Hi, Dovecot v2.3.11.3 (502c39af9) auth_passdb_request_finished appears to fire twice for an IMAP login using a Redis passdb. auth_request_finished only fires once. In the debug log below, the line "Finished passdb lookup" appears to be logged twice (once by "auth" and once by "auth-worker"). However, the actual passdb lookup against Redis is only performed once. This is confirmed by monitoring queries made against Redis. Configuration: -------------- metric auth_passdb_request_finished { event_name = auth_passdb_request_finished } auth_debug = yes passdb { auth_verbose = yes override_fields = proxy=y name = redis driver = dict args = /etc/dovecot/dovecot-redis.conf.ext } -------------- With the above configuration, I am seeing the auth_passdb_request_finished metric being incremented twice for every successful login: -------------- / # doveadm stats dump metric_name field count sum min max avg median stddev %95 auth_passdb_request_finished duration 0 0 0 0 0.00 0 0.00 0 / # curl imap://localhost -u foo:bar -XNOOP / # doveadm stats dump metric_name field count sum min max avg median stddev %95 auth_passdb_request_finished duration 2 20327 6240 14087 10163.50 10163 3923.50 14087 -------------- This is the (anonymized) debug output emitted for the above commands: -------------- Sep 19 15:03:32 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=msC166uvOL0K9HPG lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=48440 resp=<hidden> Sep 19 15:03:32 auth: Debug: redis(foo,127.0.0.1,<msC166uvOL0K9HPG>): Performing passdb lookup Sep 19 15:03:32 auth-worker(76): Debug: conn unix:auth-worker (pid=30,uid=90): auth-worker<3>: Handling PASSV request Sep 19 15:03:32 auth-worker(76): Debug: redis(foo,127.0.0.1,<msC166uvOL0K9HPG>): Performing passdb lookup Sep 19 15:03:32 auth-worker(76): Debug: redis(foo,127.0.0.1,<msC166uvOL0K9HPG>): Lookup: shared/users/foo = {"user":"foo","password":"{SHA256-CRYPT}[...]","host":"other_host","uid":1000,"home":"\/mail\/foo"} Sep 19 15:03:32 auth-worker(76): Debug: redis(foo,127.0.0.1,<msC166uvOL0K9HPG>): Finished passdb lookup Sep 19 15:03:32 auth-worker(76): Debug: conn unix:auth-worker (pid=30,uid=90): auth-worker<3>: Finished Sep 19 15:03:32 auth: Debug: redis(foo,127.0.0.1,<msC166uvOL0K9HPG>): Finished passdb lookup Sep 19 15:03:32 auth: Debug: auth(foo,127.0.0.1,<msC166uvOL0K9HPG>): Auth request finished Sep 19 15:03:32 auth: Debug: client passdb out: OK 1 user=foo proxy host=other_host uid=1000 home=/mail/foo hostip=127.0.0.2 pass=<hidden> -------------- Best regards, Eirik -- Eirik
