Pipe to PHP script using Sieve Extprograms
by Thomas 21 Apr '17

21 Apr '17

Hello, I seem to be having some issues trying to setup a pipe to PHP scripts using Sieve Extprograms. I am trying to allow each individual mailbox to setup its own PHP pipe rules (in other words, each user should be able to pipe incoming emails to a user defined PHP script). I have the following lines in my main Sieve configuration file (/etc/dovecot/conf.d/90-sieve.conf): sieve_extensions = +vnd.dovecot.pipe sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.execute sieve_plugins = sieve_extprograms I have configured a Sieve service that looks like this (/etc/dovecot/conf.d/90-sieve-extprograms.conf): service php { # Define the executed script as parameter to the sieve service executable = /var/run/dovecot/sieve-pipe/php.sh # Use some unprivileged user for executing the program user = dovenull # The unix socket located in the sieve_pipe_socket_dir (as defined in the # plugin {} section above) unix_listener sieve-pipe/php { # LDA/LMTP must have access user = vmail mode = 0600 } } Contents of /var/run/dovecot/sieve-pipe/php.sh: #!/usr/bin/php Sieve script for one of my mailboxes: require ["fileinto", "regex", "date", "relational", "vacation"]; require ["mailbox", "imap4flags", "vnd.dovecot.pipe"]; # Move spam to spam folder if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } pipe :try "php /var/www/web2/piping.php support(a)example.com" keep; This results however in the following error in my log file: main script: line 5: error: require command: unknown Sieve capability `vnd.dovecot.pipe'. main script: line 14: error: unknown command 'pipe' (only reported once at first occurence). main script: error: validation failed. I am also not quite confident I have set this up correctly. Am I heading in the right direction for what I am trying to achieve?

Hi, i am using dovecot-2.2.10-7.el7.x86_64 on centos-release-7-3.1611.el7.centos.x86_64. if i follow this tutorial https://delog.wordpress.com/2011/05/10/access-imap-server-from-the-command-… i can login to my server and successfully list the folders using tag LIST "" "*" * LIST (\HasNoChildren) "." INBOX tag OK List completed. no folders are listed using tag LIST / "*" tag OK List completed. when i request a folder listing using JavaMail it similarly sends the following command and no folders are listed a97 LIST / "*" a97 OK List completed. if i follow the tutorial again and use my gmail account instead of my dovecot installation i can successfully list folders using both methods tag LIST / "*" * LIST (\HasNoChildren) "/" "youtube" tag OK List completed. is there some way to make dovecot list folders when it receives the command LIST / "*" i note that in the listings my dovecot installation has "." in the middle and gmail has a "/"

JavaMail setFlags on readonly folder
by Gabriele Bulfon 20 Apr '17

20 Apr '17

Hi, I'm facing a strange issue using JavaMail, where Dovecot let me open "READ_WRITE" a folder with readonly ACLs (same happens on other imap servers), but then doesn't issue any error when if try to setFlags(...) on that folder. The result is that the code thinks the folder marked the messages (deleted, flagged, etc), while it actually did not. Just refreshing the folder from the java client, you get back your original messages as they were before the operation. Is there any known issue about this?

Using filter in an imapsieve script?
by Tobi 20 Apr '17

20 Apr '17

Hello list I currently have an issue with an imapsieve script on my dovecot server CentOS Linux release 7.3.1611 (Core) Dovecot 2.2.26.0 (23d1de6) Pigeonhole 2.2.26.0 The goal is to "fire" an imapsieve script upon mailclient saves message to sent folder I setup the following in 90-plugin.conf: plugin { sieve_plugins = sieve_imapsieve sieve_extprograms sieve_extensions = +vnd.dovecot.filter +vnd.dovecot.pipe +vnd.dovecot.execute sieve_filter_bin_dir = /etc/dovecot/sieve-filters sieve_pipe_bin_dir = /etc/dovecot/sieve-filters sieve_execute_bin_dir = /etc/dovecot/sieve-filters sieve_filter_exec_timeout = 10000 sieve_pipe_exec_timeout = 10000 sieve_execute_exec_timeout = 10000 imapsieve_mailbox1_name = Sent imapsieve_mailbox1_causes = COPY APPEND imapsieve_mailbox1_before = file:/home/vmail/domain/user/dovecot-crypt-sent.sieve } and the content of the sieve script is: require ["environment", "vnd.dovecot.filter", "variables", "imapsieve", "vnd.dovecot.pipe", "vnd.dovecot.execute"]; if anyof (environment :is "imap.cause" "APPEND", environment :is "imap.cause" "COPY") { filter "gpgit" "myuser(a)mydomain.tld"; } gpgit is a perl script that encrypts a given message using the users pub key and returns back the encrypted message As a sieve script for lmtp/lda it works fine and encrypted messages show up in the mailbox. But it does not work if it is used as imap sieve script There is nothing in the logs that indicates a problem with the imap sieve script. Is it possible that 'filter' is not supported for imapsieve as it changes the content of a message? Thanks for any hint tobi

RSA key not found
by Michael Segel 20 Apr '17

20 Apr '17

I’ve got a couple of issues with a new mail server set up… I’m getting the following error: warning: cannot get RSA certificate from file /etc/pki/dovecot/certs/<mycert>.pem: disabling TLS support The problem is that <mycert>.pem isn’t an RSA ticket, but a X509 certificate. The RSA ticket is in /etc/pki/dovecot/private directory. I checked both files and they are good certificates. I’m using webmin to manage my server. In webmin, the TLS certificate file is the X509 and the private key is the RSA file. So why does Postfix check the certificate link for the RSA file and not the X509? Thx -Mike

Adding secure POP3?
by ＠lbutlr 20 Apr '17

20 Apr '17

I have a working server that only allows connections over secure IMAP (port 993) and secured submission (587). However, I have one account that has been forwarding mail to gmail for many years and that is getting to be more and more of a problem as more large sites enforce DMARC. So, the only way that gmail will pull mail is via pop3, so I need to add pop3 access. 1) How do I add a secure (TLS) POP3 service to dovecot 2) can I restrict access to that to specific users? Domains? OT, but someone probably knows, is secured POP3 going to work with gmail? ===BEGIN passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } ===END I did read <https://wiki.dovecot.org/SSL/DovecotConfiguration> but it’s about adding ssl to an existing setup. -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.

my domain in both my destination and virtual_mailbox_domains?
by Michael Segel 20 Apr '17

20 Apr '17

I’m doing a new dovecot mail server for my domain. Here’s yet another thing I mucked up. I wanted to set up virtual mailboxes. One reason was that I wanted to set up virtual users for the domain so I don’t need to create user accounts just mail accounts. I followed one of the many examples / tutorials out there and I end up with the following warning message. postfix/trivial-rewrite[8818]: warning: do not list domain <machine>.<domain>.com in BOTH mydestination and virtual_mailbox_domains I checked my configuration, I don’t see where I’ve set up anything for mydestination in postfix. I’m trying to work thru the log file issues that I can find… this is just one more. To add to the confusion, I’m using webmin as my server admin UI to make life easier… yet it seems to much things up a bit Any suggestions? Thx -Mike

[Configuration question] Shared Folders: sql dict - missing information
by dovecot＠avv.solutions 19 Apr '17

19 Apr '17

Hello Community, I have implemented shared folders/acl using the 'file' driver sucessfully. Now, I want to move the shared folders information to my sql DB where I have moved all user/nets/quota information. I have read carefully the documentation (https://wiki.dovecot.org/SharedMailboxes/Shared) but, as far as I can see, only the $to and $from (+ dummy) are handled in the DB? I was expecting the same granularity (per folder + explicit rights) than found using the actual solution. Did I miss something? Or how should I implement this? (Running version 2.2.13) Than you already for your help and feedback. Cheers, A

v2.2.29.1 released
by Timo Sirainen 17 Apr '17

https://dovecot.org/releases/2.2/dovecot-2.2.29.1.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.29.1.tar.gz.sig Mainly because I had missed one cherry-pick from the release, which caused unit tests to also fail. And I didn't notice that, because make distcheck had been broken for some years now when it ran clang static analyzer, although I had assumed it would have run make check already before it failed.. On a related note, we're looking for a test engineer :) http://avoimettyopaikat.monster.fi/v2/job/View?JobID=182881783 - imapc reconnection fix was forgotten from 2.2.29 release, which also made "make check" fail in a unit test - dict-sql: Merging multiple UPDATEs to a single statement wasn't actually working. - Fixed building with vpopmail

several misc questions, public folders and sharing, quota, ssl
by David Mehler 15 Apr '17

15 Apr '17

Hello, I'm running dovecot 2.29 on a freebsd 10.3 system. I'm wanting to optimize how the system is running and have a few misc questions. First ssl, is my cipher list good? I'm trying for pfs and wanting to ensure these cipherlist is appropriate: ssl_cipher_list = EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH Next, a new feature that I'm trying for is virtual folders that store All messages. My understanding of this is that it stores a version of every received message in one place? I've got the virtual plugin loaded and have: mailbox virtual/All { comment = All my messages special_use = \All } I've got a directory /home/vmail/example.com/username/virtual under which is an ALL folder both directories are accessible to the vmail user, yet there's no contents in this folder and it's showing up nowhere. Next, quota warnings, are not being sent at all. I set up a testuser with a quota of 2 mb, then sent a message to that user getting the box to 95% full, and no message. Took the user overquota with the next message, still nothing, and a third message did trigger my custom quota exceeded message and the message was bounced. I'm wanting to implement public folders. My mailboxes are all virtual, and they are stored under /home/vmail/example.com/username and /home/vmail/example.org/username in the maildir format. I've got one user uid and gid of 999 name of vmail who owns all the mailboxes. I've separated out public folders storing them under /home/vmail/public. I've created one mailbox called TestFolder and new, cur, and tmp directories under it. This is what it looks like: ls -la /home/vmail/public total 24 drwx------ 4 vmail vmail 512 Apr 13 18:23 ./ drwx------ 8 vmail vmail 512 Mar 15 10:34 ../ drwxr-xr-x 5 vmail vmail 512 Apr 13 18:16 TestFolder/ drwxr-xr-x 5 vmail vmail 512 Apr 13 18:25 TestFolder1/ -rw------- 1 vmail vmail 8 Apr 13 18:15 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 Apr 13 18:15 dovecot-uidvalidity.58eff89a -rw------- 1 vmail vmail 688 Apr 13 18:24 dovecot.list.index.log ls -la /home/vmail/public/TestFolder total 28 drwxr-xr-x 5 vmail vmail 512 Apr 13 18:16 ./ drwx------ 4 vmail vmail 512 Apr 13 18:23 ../ drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 cur/ -rw-r--r-- 1 vmail vmail 51 Apr 13 18:16 dovecot-uidlist -rw-r--r-- 1 vmail vmail 304 Apr 13 18:16 dovecot.index.log drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 new/ drwxr-xr-x 2 vmail vmail 512 Apr 13 18:13 tmp/ ls -la /home/vmail/public/TestFolder1 total 20 drwxr-xr-x 5 vmail vmail 512 Apr 13 18:25 ./ drwx------ 4 vmail vmail 512 Apr 13 18:23 ../ drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 cur/ drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 new/ drwxr-xr-x 2 vmail vmail 512 Apr 13 18:25 tmp/ The public/TestFolder is showing up fine and I can switch to it. The public/TestFolder1 is not showing up at all so I'm not seeing it and can't switch to it. Any ideas? My second question involves public folders and domain sharing. Are public folders accessible to all users and all domains? I've got two domains example.com and example.org i'd like to create a folder that some users in example.com can share with some users in example.org, not necessarily all users in those domains should be able to see the folders. Ideas welcome. Thanks.

Accessing Shared Mailbox, FQDN not appended to user
by Ed Nitido 15 Apr '17

15 Apr '17

Hey all long time, I recently upgraded Dovecot from 2.1.15 to 2.2.29.1 on my Debian Wheezy box and thought I'd tackle shared mailboxes. I can grant fine, using SETACL in telnet . SETACL mine vsun(a)test.domain.com lr . OK Setacl complete (0.596 + 0.000 + 0.595 secs). . GETACL mine * ACL mine vsun(a)test.domain.com lr edward(a)test.domain.com lrwstipekxacd However, logging in as vsun(a)test.domain.com, the logs shows the MASTER IN user doesn't get FQDN. Instead of edward(a)test.domain.com it just shows edward@test How come it only show's a partial domain? Thanks!

Cutting down on sql connections

Hello, I'm running dovecot 2.29 on a freebsd 10.3 system. I'm trying to cut down queries to my database and tried to do a userdb static and prefetch.

Trouble setting up dovecot/postfix/mysql with virtual mailboxes..
by Michael Segel 14 Apr '17

14 Apr '17

Hi, I’m building a new linux box to replace my current DNS/Mail server for my SOHO. I was going to set up postfix/dovecot/mysql so I can support virtual users. I also use Webmin to make admin easier. I ran in to a couple of snags. When I first got it set up, mail went to the virtmail user and I could use my Mac mail client to read the mail. Everything was working when testing it. I was working on my TLS certificates and I broke something. I don’t know what I did, but now it’s going to the local mailbox instead. (MailDir folder) Since most of my time is doing other things, I am hoping someone could point me in the right direction. Thx

Trouble compiling 2.2.29.1

13 Apr '17

Not sure what I'm doing wrong but I run this: ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-maintainer-mode --with-mysql and it forks thousands of copies of config.guess and will eventually lock up the computer. What am I doing wrong?

Can sieve feed mails to a pipe like procmail can?
by Peter Kielbasiewicz 13 Apr '17

13 Apr '17

Currently I use procmail to filter mails according to specific tokens and trigger certain actions. For that I feed mails which match certain criteria to a pipe which then post processes the mail right when it arrives. >From what I found I could use a workaround with sieve by storing mails somewhere and then work on those at certain intervals. But this is an awkward solution which causes delays and extra work for locking and post processing. I read that sieve be the more modern system but without the post-processing feature it is no replacement for procmail to me. Peter

Hello List, i have a working dovecot imap service running with multiple clients running fine, even iOS. What's anying is, that only on iOS ( ) i see a huge bunch of .CONTROL directories - marked grey. It seems to be a copy of the existing folder structure.

Released Pigeonhole v0.4.18 for Dovecot v2.2.29.
by Stephan Bosch 12 Apr '17

12 Apr '17

Hello Dovecot users, Here's the definitive 0.4.18 release. There were no changes since the release candidate. Changelog v0.4.18: + imapsieve plugin: Implemented the copy_source_after rule action. When this is enabled for a mailbox rule, the specified Sieve script is executed for the message in the source mailbox during a "COPY" event. This happens only after the Sieve script that is executed for the corresponding message in the destination mailbox finishes running successfully. + imapsieve plugin: Added non-standard Sieve environment items for the source and destination mailbox. - multiscript: The execution of the discard script had an implicit "keep", rather than an implicit "discard". The release is available as follows: https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.18.t… https://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.18.t… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.2.29.rc1 released
by Timo Sirainen 11 Apr '17

11 Apr '17

http://dovecot.org/releases/2.2/rc/dovecot-2.2.29.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.29.rc1.tar.gz.sig Planning to release v2.2.29 on Monday. Please find and report any bugs before that. * When Dovecot encounters an internal error, it logs the real error and usually logs another line saying what function failed. Previously the second log line's error message was a rather uninformative "Internal error occurred. Refer to server log for more information." Now the real error message is duplicated in this second log line. * lmtp: If a delivery has multiple recipients, run autoexpunging only for the last recipient. This avoids a problem where a long autoexpunge run causes LMTP client to timeout between the DATA replies, resulting in duplicate mail deliveries. * config: Don't stop the process due to idling. Otherwise the configuration is reloaded when the process restarts. * mail_log plugin: Differentiate autoexpunges from regular expunges * imapc: Use LOGOUT to cleanly disconnect from server. * lib-http: Internal status codes (>9000) are no longer visible in logs * director: Log vhost count changes and HOST-UP/DOWN + quota: Add plugin { quota_max_mail_size } setting to limit the maximum individual mail size that can be saved. + imapc: Add imapc_features=delay-login. If set, connecting to the remote IMAP server isn't done until it's necessary. + imapc: Add imapc_connection_retry_count and imapc_connection_retry_interval settings. + imap, pop3, indexer-worker: Add (deinit) to process title before autoexpunging runs. + Added %{encrypt} and %{decrypt} variables + imap/pop3 proxy: Log proxy state in errors as human-readable string. + imap/pop3-login: All forward_* extra fields returned by passdb are sent to the next hop when proxying using ID/XCLIENT commands. On the receiving side these fields are imported and sent to auth process where they're accessible via %{passdb:forward_*}. This is done only if the sending IP address matches login_trusted_networks. + imap-login: If imap_id_retain=yes, send the IMAP ID string to auth process. %{client_id} expands to it in auth process. The ID string is also sent to the next hop when proxying. - fts-tika: Fixed crash when parsing attachment without Content-Disposition header. Broken by 2.2.28. - trash plugin was broken in 2.2.28 - auth: When passdb/userdb lookups were done via auth-workers, too much data was added to auth cache. This could have resulted in wrong replies when using multiple passdbs/userdbs. - auth: passdb { skip & mechanisms } were ignored for the first passdb - oauth2: Various fixes, including fixes to crashes - dsync: Large Sieve scripts (or other large metadata) weren't always synced. - Index rebuild (e.g. doveadm force-resync) set all mails as \Recent - imap-hibernate: %{userdb:*} wasn't expanded in mail_log_prefix - doveadm: Exit codes weren't preserved when proxying commands via doveadm-server. Almost all errors used exit code 75 (tempfail). - ACLs weren't applied to not-yet-existing autocreated mailboxes. - Fixed a potential crash when parsing a broken message header. - cassandra: Fallback consistency settings weren't working correctly. - doveadm director status <user>: "Initial config" was always empty - imapc: Various reconnection fixes.

How to use quota with dovecot
by Mik J 11 Apr '17

11 Apr '17

Hello, I would like to use quotas with dovecot and things are not clear to me. I read this page https://wiki2.dovecot.org/Quota 1) I did this # ls /usr/local/lib/dovecot/lib10_quota_plugin.so /usr/local/lib/dovecot/lib10_quota_plugin.so # grep mail_plugins /etc/dovecot/conf.d/10-mail.conf mail_plugins = notify replication quota Then the page tells about 20-imap.conf but an explanation is written # Space separated list of plugins to load (default is global mail_plugins). So what is that default global mail_plugins ? Is it the one coming from 10-mail.conf ? 2) I tried both use this mail_plugins = $mail_plugins quota in 20-imap.conf or comment it. And restarted dovecot each time Then commented out in 90-quota.conf quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_grace = 10%% } But I have this message # doveadm quota recalc -u user(a)mydomain.org doveadm(user(a)mydomain.org): Error: Quota not enabled Does anyone knows why ?

v2.2.29 released
by Timo Sirainen 11 Apr '17

11 Apr '17

https://dovecot.org/releases/2.2/dovecot-2.2.29.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.29.tar.gz.sig * passdb/userdb dict: Don't double-expand %variables in keys. If dict was used as the authentication passdb, using specially crafted %variables in the username could be used to cause DoS (CVE-2017-2669) * When Dovecot encounters an internal error, it logs the real error and usually logs another line saying what function failed. Previously the second log line's error message was a rather uninformative "Internal error occurred. Refer to server log for more information." Now the real error message is duplicated in this second log line. * lmtp: If a delivery has multiple recipients, run autoexpunging only for the last recipient. This avoids a problem where a long autoexpunge run causes LMTP client to timeout between the DATA replies, resulting in duplicate mail deliveries. * config: Don't stop the process due to idling. Otherwise the configuration is reloaded when the process restarts. * mail_log plugin: Differentiate autoexpunges from regular expunges * imapc: Use LOGOUT to cleanly disconnect from server. * lib-http: Internal status codes (>9000) are no longer visible in logs * director: Log vhost count changes and HOST-UP/DOWN + quota: Add plugin { quota_max_mail_size } setting to limit the maximum individual mail size that can be saved. + imapc: Add imapc_features=delay-login. If set, connecting to the remote IMAP server isn't done until it's necessary. + imapc: Add imapc_connection_retry_count and imapc_connection_retry_interval settings. + imap, pop3, indexer-worker: Add (deinit) to process title before autoexpunging runs. + Added %{encrypt} and %{decrypt} variables + imap/pop3 proxy: Log proxy state in errors as human-readable string. + imap/pop3-login: All forward_* extra fields returned by passdb are sent to the next hop when proxying using ID/XCLIENT commands. On the receiving side these fields are imported and sent to auth process where they're accessible via %{passdb:forward_*}. This is done only if the sending IP address matches login_trusted_networks. + imap-login: If imap_id_retain=yes, send the IMAP ID string to auth process. %{client_id} expands to it in auth process. The ID string is also sent to the next hop when proxying. + passdb imap: Use ssl_client_ca_* settings for CA validation. - fts-tika: Fixed crash when parsing attachment without Content-Disposition header. Broken by 2.2.28. - trash plugin was broken in 2.2.28 - auth: When passdb/userdb lookups were done via auth-workers, too much data was added to auth cache. This could have resulted in wrong replies when using multiple passdbs/userdbs. - auth: passdb { skip & mechanisms } were ignored for the first passdb - oauth2: Various fixes, including fixes to crashes - dsync: Large Sieve scripts (or other large metadata) weren't always synced. - Index rebuild (e.g. doveadm force-resync) set all mails as \Recent - imap-hibernate: %{userdb:*} wasn't expanded in mail_log_prefix - doveadm: Exit codes weren't preserved when proxying commands via doveadm-server. Almost all errors used exit code 75 (tempfail). - ACLs weren't applied to not-yet-existing autocreated mailboxes. - Fixed a potential crash when parsing a broken message header. - cassandra: Fallback consistency settings weren't working correctly. - doveadm director status <user>: "Initial config" was always empty - imapc: Various reconnection fixes.

How to migration my mails from another server ?
by Mik J 10 Apr '17

10 Apr '17

Hello, I would like to host my mails and I would like to retrieve my existing mailbox content from my ISP My ISP ====== I don't have root access on the server The server seem to use Dovecot according to the banner. My machine ========== I have root access on the server I use Dovecot 2.2.21 I use Maildir I read this page multiple times but it's not clear to me https://wiki2.dovecot.org/Migration/Dsync "Set up configuration for the IMAP server you wish to migrate from" Is it my ISP's server or my server ? In which configuration file should I do this ? The same for this option dsync_features = empty-header-workaroundwhere is it supposed to be configured ? My most important case is quite "simple": the mailboxes (there are 2 or 3) I want to migrate don't exist on my machine, so there is no such problems as merge existing mails. Will this migration use imap and retrieve the content of the mails ? Will it use port 143 or 993 ? I'll use the backup option I have another case which there are mails on both servers. So I would like to keep existing mails on my machine. I'll use the sync -1 option ? Thank you

[Bug] FTS invalid address parsing
by azurit＠pobox.sk 10 Apr '17

10 Apr '17

Hi, i found another bug in FTS while parsing quoted-printable/base64-encoded sender's name inside 'From' header (again, i was figuring out why some of messages cannot be searched). Header: From: =?UTF-8?Q?A=2CB?= <test(a)example.com> Data send to Solr by Dovecot: <field name="from">A@, B &lt;test(a)example.com&gt;</field> Header: From: =?UTF-8?Q?A_B=2CC?= <test(a)example.com> Data send to Solr by Dovecot: <field name="from">A@</field> Header: From: =?UTF-8?B?QSBCLEMK?= <test(a)example.com> Data send to Solr by Dovecot: <field name="from">A@</field> Dovecot 2.2.27. azur

[Bug] FTS double escaping
by azurit＠pobox.sk 09 Apr '17

09 Apr '17

Hi, i'm trying to resolve few problems with indexing 'From' headers using FTS/Solr. I was tcpdumping the communication between Dovecot and Jetty/Solr and noticed that 'From' headers, which includes also sender's name, are double escaped. This is what was Dovecot sending to Solr: </field><field name="from">Name Surname &lt;test(a)example.com&gt;</field></doc></add> As you can see, characters < and > were escaped to < and > which were, again, escaped to &lt; and &gt;. This is doing problems while trying to index whole e-mail address, as Solr sees it as '<test(a)example.com>'. I spend hours trying to figure out why i'm able to search in all parts of e-mail addresses but searching for full and exact e-mail address was successfull ONLY for messages which doesn't include sender's name in 'From' header. Finally, after i found this bug, this fixed all search problems: <filter class="solr.PatternReplaceFilterFactory" pattern="&lt;" replacement=""/> <filter class="solr.PatternReplaceFilterFactory" pattern="&gt;" replacement=""/> I hope that, at least, this bug, reported by me, will be fixed. Thank you. azur

sieve does not seem to be working
by Robert Moskowitz 09 Apr '17

09 Apr '17

my local.conf has: # 90-sieve.conf plugin { sieve_before = /home/sieve/globalfilter.sieve } and cat /home/sieve/globalfilter.sieve require ["fileinto","mailbox"]; if anyof ( header :contains "X-Spam-Flag" "YES", header :contains "subject" "***SPAM***" ) { fileinto :create "Spam"; } There IS a globalfilter.svbin when I tried: sendmail -i testit3(a)test.htt-consult.com < sample-spam-GTUBE-junk.txt amavis is flagging it as ***Spam*** but it stays in inbox. So I tried: sieve-test -e -l /home/vmail/test.htt-consult.com/testit3/ /home/sieve/globalfilter.sieve /home/vmail/test.htt-consult.com/testit3/cur/1491512409.M371278P6513.z9m9z.test.htt-consult.com\,S\=1823\,W\=1868\:2\, info: msgid=<GTUBE1.1010101(a)example.net>: stored mail into mailbox 'Spam'. sieve-test(root): Info: final result: success And it DID get copied to Spam, not moved. I am now seeing it in inbox and Spam. Of course ownership on the message in Spam were wrong (root:root instead of vmail:mail, but I fixed that). So two questions, probably linked: Why did sieve not work. Is the subject test case sensitive? If it is case sensitive, why did the sieve-test work? thanks

Pigeonhole Sieve Extprograms Plugin
by KT Walrus 09 Apr '17

09 Apr '17

Just discovered the Pigeonhole Sieve Extprograms plugin (https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms <https://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms>)… I currently have Postfix configured to run a script to store all incoming messages into a Mysql DB and a batch job that retrieves the messages in the DB, processes them and delivers them to the recipients' Dovecot servers. Seems to me it might be better to have Postfix deliver all incoming messages directly to a single Dovecot mailbox and use this Sieve plugin to do the whole job of updating the DB, processing the message, and delivering to the recipients. Also, I have a need to implement updating the DB when the recipient reads a message for the first time (setting the \Seen flag). Would this work best to execute a script using this Sieve plugin from a IMAP Sieve script that watches for \Seen flag changes? This might be a whole lot better than the way I was thinking of doing it before. I’m basically implementing mailing lists where the senders receive a notification reply with a link to a web page where the message may be edited/deleted before it is sent to recipients (after a fixed amount of time has elapsed). This gives the sender the opportunity to change his mind before it is too late or to send to recipients immediately (by marking the message as Urgent). Also, even after the message has been sent out, I want to allow the sender to be able to delete it in the recipients mailboxes if they have not read it yet (downloaded it to their email client) or to see which recipients have read the message (and when they read/downloaded it for the first time). Both the sender and the recipients will have Dovecot mailboxes so I want to give more control over the messages for their entire lifetimes (both for senders and for recipients) than normal email does. Any thoughts? Kevin

Released Pigeonhole v0.4.18.rc1 for Dovecot v2.2.29.rc1.
by Stephan Bosch 09 Apr '17

09 Apr '17

Hello Dovecot users, This is a rather small release. It fixes one important bug in the new discard script feature. It also adds a couple of new features for IMAPSieve. Changelog v0.4.18: + imapsieve plugin: Implemented the copy_source_after rule action. When this is enabled for a mailbox rule, the specified Sieve script is executed for the message in the source mailbox during a "COPY" event. This happens only after the Sieve script that is executed for the corresponding message in the destination mailbox finishes running successfully. + imapsieve plugin: Added non-standard Sieve environment items for the source and destination mailbox. - multiscript: The execution of the discard script had an implicit "keep", rather than an implicit "discard". The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.18… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.18… 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

Updating mysql db when messages first read by IMAP user
by KT Walrus 09 Apr '17

09 Apr '17

I need to implement updating a mysql db when the \SEEN flag is set by IMAP. New message delivery is done by having Postfix store all new inbound messages in a mysql db and a batch job watching the db for new messages and delivering them to the correct Dovecot server for the recipients. The batch job leaves a log entry in the db (for each recipient) with the current timestamp and adds a header with the log id to the outgoing message that is sent to Dovecot. The log table has a column for the first read timestamp which is set to 0 initially. I plan on implementing a Sieve IMAP script that watches for changes to the \SEEN flag and sends a mailto: notify message that contains the log id (from the message header) and the current date to a mail address dedicated for keep track of \SEEN flag changes. The notify message will be delivered to this mail address where a batch job watches that mail address and updates the db for the log id in the notify message with the timestamp and the current date if the row in the log table has a first read timestamp of 0. I plan on providing a web page that the sender can use to see whether the messages they have sent have been seen by the recipients. The web page will show other info too, but the part that I need to implement next is updating the db when a sent message has been read by the recipients of the message. Is this a good way to do this? Or, is there a better way than using an IMAP Sieve script to send notify messages? Is there any other way to have a Sieve script update a mysql database? Or, is there some other mechanism in Dovecot to use instead of an IMAP Sieve script? Kevin

IMAPSieve Changed flags cause?
by MRob 09 Apr '17

09 Apr '17

RFC 6785 says I should be able to run scripts when a command changes flags on a message but I can't understand what to put in imapsieve_mailboxXXX_causes. Dovecot logs something like STORE as an invalid cause. How do I run an administrator Sieve script caused from change in flags?

LAYOUT=fs and subfolders listing
by Dovecot＠9livesdata 07 Apr '17

07 Apr '17

dovecot-2.2.28-1.el6_31.wing.x86_64 I've created this public shared namespace with namespace public2 { type = public separator = . prefix = Public2. location = maildir:/mail/public2:INDEX=/mail/%u/public:LAYOUT=fs:DIRNAME=.store subscriptions = no } and I'm using the "imap_client_workarounds = tb-extra-mailbox-sep" and filesystem structure listed at the end. The problem is that with this configuration thunderbird (and roundcubemail) shows the Public2 namespace but empty - without any folders. I've tried with another DIRNAME=StoR - same effect If I will not use DIRNAME at all(and no .stor directories) TB sees the f1 f2 folders but not the f2/s1 subfolder. Just like it would not list any subfolders for subscription. Within TB I can create subfolder say f1/mysub1 but after it's unsubscribed cannot be subscribed again(not shown in listing) Can You provide any hints? I can live without the DIRNAME= but it has to list subfolders for subscription.

Running sievec as user vmail
by Robert Moskowitz 07 Apr '17

07 Apr '17

My sieve problem ended up a permissions problem. I ran sievec as root and .svbin needs vmail:mail ownership. I could always just add the chown command to my process, but I wonder if there is some 'clean' way to run sievec as user vmail while logged in as root? thanks

Doubt with imap/imap-login processes in proxy server
by Angel L. Mateo 07 Apr '17

07 Apr '17

Hi, I have a question I have not cleared after reading https://wiki.dovecot.org/LoginProcess. I'm developing a proxy server (without director, because the backend server is specified by a ldap lookup). My question is: the limit of imap (or pop3) concurrently users that the proxy can handle is determined by the imap-login limit or the imap one? -- Angel L.

Spam instead of Junk folder
by Robert Moskowitz 07 Apr '17

07 Apr '17

Traditionally I have used 'Spam' as the folder name for all those emails that get tagged as, well Spam. But it seems that the standard is now 'Junk' as from 15-mailboxes.conf # Space separated list of IMAP SPECIAL-USE attributes as specified by # RFC 6154: \All \Archive \Drafts \Flagged \Junk \Sent \Trash #special_use = If I have in local.conf # 15-mailboxes.conf namespace inbox { mailbox Spam { special_use = \Junk } } This would auto make Spam, but: Would Junk (and all the others specified in 15-mailboxes.conf) still get created? What actually controls which folders get created?

Dovecot impatient with mysql?
by Robert Moskowitz 06 Apr '17

06 Apr '17

It seems dovecot is impatient with connecting with mysql, as I see in maillog entries like: Apr 6 11:48:30 z9m9z dovecot: dict: Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) - waiting for 5 seconds before retry Apr 6 11:48:35 z9m9z dovecot: dict: Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) - waiting for 25 seconds before retry I suspect it does connect eventually. This is a test system with only 1GB of memory and free reports: total used free shared buff/cache available Mem: 1025484 696344 24556 21528 304584 251552 Swap: 524284 92168 432116 The production box has 2GB, so if the problem is mysql is swapping out, that will be 'fixed', if it is processor, well this is an ARMv7 duo core, as is the production box. I am considering buying the new quad core. Is there anything I can do to get dovecot more patient with mysql, or just ignore there messages? thank you

Replication for Pigeonhole ManageSieve
by Joe Nahmias 06 Apr '17

06 Apr '17

Hello, I currently have one machine running postfix SMTP server as MTA along with dovecot IMAP server for email. Although it only supports a handful of users, email service is important to us all; so I'm looking to make this a more fault-tolerant / highly-available system. To that end, I'm planning on configuring postfix to use deliver/dovecot-lda as my MDA (using procmail at the moment), spinning up another machine with postfix/dovecot and setting up master/master replication using dsync/doveadm-sync. My reading on the subject suggests that this should (given appropriate MX & SRV dns records) make traffic balanced across both nodes, and the system should be resilient if one of the nodes should fail without the need for much/any human intervention. In order to replace the functionality that procmail currently provides as MDA, I was thinking to use Sieve. Fortunately, it seems the Pigeonhole project provides almost everything I need on the server side to make this work. The one potential gap I have identified is the syncing of the sieve scripts between the two machines. Has any one dealt with this and come up with a good solution? Does dsync already handle this and I just haven't figured it out? Let me know if my question is best directed elsewhere. Thanks in advance for any help, --Joe PS - please cc me as I don't subscribe to this list.

The TLS encryption happens on the network > layer whereas the encryption method is used at the IMAP level. Those are authentication methods. However, Googling the heck out of the error message, it appears the OP's error message is a common problem fixed by resetting the PopProxy configuration https://social.technet.microsoft.com/Forums/ie/en-US/40eb0164-0bcf-499a-940… https://blog.zubairalexander.com/outlook-error-0x800ccc1/ Joseph Tam <jtam.home(a)gmail.com>

Problem with Dovecot and BlackBerry

Hi all, i've got a strange behaviour with a BlackBerry Classic Phone (BBOS 10.3.2.2876) in combination with Dovecot 2.2.13 while trying to fetch mails. Before burying myself into debugging sessions, i try to get an understanding if the following is a Client- or a Server-specific error in the behaviour: CIGA8 UID FETCH 10009:10035 (UID FLAGS) (CHANGEDSINCE NOMODSEQ) CIGA8 BAD Error in IMAP command UID FETCH: Invalid CHANGEDSINCE modseq.
