Dovecot 2.2.24 coredump client_check_command_hangs()
by Peter Eriksson 22 Jun '16

22 Jun '16

I’m seeing core dumps from Dovecot’s imap process (around 1/day currently) from client_check_command_hangs(). Dovecot 2.2.24 OS: Solaris 10 CPU: x86 Filesystem: Local ZFS Most crashes are associated with one user (with 25GB of mail in his mailboxes) but some (two) are also associated with other user with “just” 10GB mail. Please find enclosed various log files/traces. Let me know if there is something else I might be able to provide that might give more insight into this. The output is from one of the “25GB”-user crashes. He is able to access mail normally most of the time though so the client recovers and he hasn’t reported this issue to us. — [Lı.U] SysAdmin KITVS-IFM & ITI-NET IT.LiU.SE +46-13-28 2786

Fedora + Dovecot - only one client can connect per user?
by Thomas Cameron 20 Jun '16

20 Jun '16

Howdy - I am running dovecot-2.2.24-1.fc23.x86_64 on Fedora 23. It's up to date as of last night. When I log in from a desktop using Thunderbird on Linux, my Android phone (Nexus 6P) stops receiving mail. It happens if I'm on my laptop or my desktop. My wife has the same problem using Thunderbird on Windows. If she leaves the house and forgets to shut down her MUA, her phone can't retrieve messages. Is this expected behavior? Can I change it? I feel like it's pretty common for folks to have multiple devices which access the same mail account. Between phones, tablets, PCs, etc., this seems like a pretty common scenario. It's a pretty vanilla setup: [root@wintermute ~]# dovecot -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # OS: Linux 4.4.4-301.fc23.x86_64 x86_64 Fedora release 23 (Twenty Three) mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_cipher_list = PROFILE=SYSTEM ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } Thanks!

Recipient delimiter and lmtp proxying
by Dave 20 Jun '16

20 Jun '16

Hi, I'm attempting to proxy lmtp using director to hash to the same backend as pop3/imap. My pop3/imap users are of the form: username and my lmtp users are of the form: <username@domain> Where domain is fairly redundant but does carry some useful information. Now, I can proxy lmtp using user=%{username} and destuser=%{orig_user}, and this all appears to work correctly. However, if I also try to pass a detail part through to the backend the lmtp users now take the form: <username+detail@domain> I can still use user=%{username} with recipient_delimiter = +, and the detail is correctly stripped, hashing works as expected. However, I can no longer use destuser=%{orig_user} Because recipient_delimiter = +, destuser becomes: <username@domain> And the detail part never reaches the backend. There doesn't appear to be any variables suitable for the destuser expansion - %{auth_user} is unsupported (UNSUPPORTED_VARIABLE_auth_user) on override_fields and in the sql passdb driver. Is there any "correct" way to do this? I can think of a couple of approaches that may work, but both seem like hacks to me: 1. Unset recipient_delimiter and manually strip the detail from the username in the passdb lookup. 2. Give up on passing detail via the login and instead pass the detail via a message header to sieve. Any thoughts/suggestions? -- Dave

Migrate Dovecot email archive
by Marco Usai 20 Jun '16

20 Jun '16

Yesterday I'vemigrated Dovecot mail archive between two servers using the procedure below: 1) Createon the new server the same email accounts existing on the old server. 2) Transferthe "tarred" mail folder from the old to the new server. For testingpurposes, on Outlook 2007 I've deleted a .pst cache file, forcing the client todownload all emails again. The switchwas absolutely transparent without any problem. All the emails were availableand Outlook 2007 noticed no changes. Can Iconsider this a correct procedure or should I use some tools like Dsync ?

Custom storage backend

Hello, We use a storage backend that is using non-standard apis. We would like to know if there is some way to write a storage backend as a plugin instead of hardcoding our changes directly into the dovecot source ? Thanks.

archive all saved IMAP messages
by KT Walrus 18 Jun '16

18 Jun '16

I need to archive (i.e., send to another mail server) all messages saved on my mail servers. I’ve implemented for SMTP submission, but haven’t figured out how to archive messages saved by IMAP (like to Drafts, Sent, etc.). How would I best implement this? Can I enable Sieve plugin for IMAP? Or, some other method? Like one way backup to archive server? I really only need to archive the messages sent/saved by a user and not the messages received from other users. Kevin

tlsv1 alert unknown ca: SSL alert number 48
by Maurizio Dall'Acqua 18 Jun '16

18 Jun '16

Hi, I have set up a mail server with postfix+dovecot 2.2.13 on my raspberry pi running Raspbian Jassie OS. Now I would like to add an on-line e-mail client like Squirrelmail or Roundcube. I was able to start up these two clients but when I try to login I get this error message in the dovecot log: tlsv1 alert unknown ca: SSL alert number 48 But I have inserted the self-signed certificate and key in /etc/dovecot/conf.d/10-master.conf Moreover, I can send and receive e-mails from/to my server, and I can login successfully to dovecot IMAP with Thunderbird. Can somebody give me a clue on how to solve this problem? Any help would me much appreciated. Regards, Maurizio

Mail dates
by ＠lbutlr 18 Jun '16

18 Jun '16

Where exactly does dovecot get the date that it reports via IMAP? I have a lot of messages that were restored from an archive and so all have the same date, despite being over the span over several years. I tried setting the timestamps of the files to the date in the Received header, but that didn’t seem to make any difference to what my IMAP clients see. Do I have to rename the files to the right epoch seconds in order for dovecot to show the right dates to the IMAP clients? … It seems I’ve been here before, but I don’t remember the solution … -- 'What is this thing, anyway?' said the Dean, inspecting the implement in his hands.

Advice needed: SMTP/LMTP or IMAP for internal message delivery
by KT Walrus 17 Jun '16

17 Jun '16

I’ve implemented “next day” delivery this week by taking messages submitted through Postfix, queuing the messages in a MySQL database, and sending them out for delivery through another Postfix instance/Dovecot LMTP proxy with final delivery using the destination mail servers LMTP service. Delivery is sent to a “next day” mail server which is sync’d to the recipient’s mail server using “doveadm sync -A tcp:next-day-mail:12345” on each mail server in the early morning. This all appears to be working well. I do have a need to deliver these messages into specific mail folders in the recipient’s mailbox and I was planning on using global Sieve scripts running on the “next day” mail server to place the messages in the proper folder (not all messages are delivered to the INBOX folder). I am using a PHP script to move the messages from Postfix to the MySQL database and then later sending them via SMTP to the internal Postfix instance for delivery to the “next day” mail server. I started investing how to code the Sieve scripts today and it occurred to me that I could greatly simplify message delivery by using IMAP to deliver the messages to the “next day” mail server. The PHP script would be able to deliver the exact message that should be stored to the proper folders setting the \Seen flags appropriately. My backend “next day” mail server already supports Master password login so I figure the PHP script should be able to login via IMAP to access the folders in the recipient mailboxes. Also, the PHP script could do other mailbox maintenance tasks when it connects to the user’s mailbox such as purge folders by age, message count, etc. The PHP script could also retrieve info about the current state of the user’s mailbox folders (like the date of the oldest unread message, how many messages have been read in the last week or so, etc) and store this data in the MySQL DB. I’m looking for any advice on whether to scrap the current plan of deploying internal Postfix SMTP/Dovecot LMTP proxy/Dovecot LMTP/Sieve script for “next day” mail delivery and just write PHP script to access Dovecot IMAP (direct to the “next day” mail server or to the user’s mail server for “immediate” delivery). This would allow me to drop using Dovecot LMTP at all. Postfix SMTP would only be configured to invoke a PHP script to deliver messages to the database (which is already implemented). Postfix would still use Dovecot IMAP authentication, but only Dovecot IMAP service would need to be “highly available”. Any opinions? Should I dump LMTP? Kevin

Migrate email account from Dovecot to Dovecot servers
by Marco Usai 17 Jun '16

17 Jun '16

Hello, 1) I needto migrate some mbox imap email accounts from a shared webhosting provider toanother one. 2) Bothservers seem to use Devecot, as a telnet command on port 143 shows an identicalresponse:* OK[CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE NAMESPACESTARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. 3) I don'tknow Dovecot version because I don't have access to "dovecot --version"command. 4) I can'tuse "doveadm-sync" because the command is not available on my sharedhosting account. 5) I preferto leave imapsync perl script as the last option because I want to preserve theUID. So, I needto know what migration procedure can be adopted: if I copythe /home/user/mail/ directory containing all email account from the sourceserver to the destination server, can I expect to see all accounts working withall the emails transferred ? Should I firstcreate from cPanel all the email account with identical names and password onthe destination server ? Anysuggestion will be much appreciated. Thanks in advance!

Double variable expansion / multiple password mechanisms
by Leon Kyneur 17 Jun '16

17 Jun '16

Hi, Trying to solve the problem of supporting multiple auth mechanisms + proxy and really don't want to store user passwords in plain test and fine to do master user to backend. I had the crazy thought I could do something like the following: For each user Store supported password schemes as LDAP attributes: userPasswordCRAM-MD5: {CRAM-MD5}xxx userPasswordDIGEST-MD5: {DIGEST-MD5}xxxx userPasswordSCRAM: {SCRAM-SHA-1}xxxx userPasswordNTLM: {NTLM}xxxx then: =password=%{ldap:userPassword%m} <- Though this doesn't work.. just wondering if it could possibly work or if I should give up on this crazy idea :) Thanks Leon

Mailbox location
by Doug Hardie 17 Jun '16

17 Jun '16

I am running a small server with a fixed number of users. Postfix is using dovecot lda so that I can run pigeonhole. I have setup a user file with the ids and passwords and everything authenticates properly. Postfix uses that also. However, mail is consistently delivered to user@domain. How do I tell it to deliver to just user? I have tried setting a variety of different things like: 10-mail.conf:mail_location = maildir:/var/mail/home_mail/%u userdb { driver = static args = uid=2222 gid=2222 home=/var/mail/home_mail/%u } and a few other things. None of them affected the mailbox location. Fortunately, this is a test system as I probably have mucked up the config files by now. — Doug

sieve-extprogram: How to hand over a variable or pipe a mail so a shell script?
by M. Koehler 17 Jun '16

17 Jun '16

Hi, I´m just playing around with sieve-extprogram but it didn´t works like I think. I want a. execute a shell script that get the subject as parameter my try: require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute :input "${1}" "exec-test"; keep; } and require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute "exec-test" "${1}"; keep; } The shell script will create a file with $1 as text. But I didn´t get any output - the created file is empty b. later the complete mail should piped to the shell script require ["fileinto","variables","envelope","vnd.dovecot.execute"]; if header :contains "Subject" "123test" { execute :pipe "exec-test"; keep; } This should (as http://hg.rename-it.nl/dovecot-2.2-pigeonhole/raw-file/tip/doc/rfc/spec-bos… described) hand over the complete mail to the script But I don´t know how I handle the complete mail with a shell script? I think the mail will not hand over as a parameter to the shell script, right? But how should I store the mail into a file or should I pipe it through a sed command line (and so one) into a shell script? Hope someone could bring some lights into my darkness :) Best regards, Michael

quota rules for mail users
by mkawada＠redhat.com 16 Jun '16

16 Jun '16

Dear All, Is it possible to make quota rules under $HOME/Maildir/* mailboxes with a specific command such as 'edquota' when the first email arrives at the $HOME/Maildir/{new,cur,tmp} of a user. In the below example, the <UserB> is the one who gets an email for the first time. edquota -p <UserA> <UserB> ---man edquot--- -p, --prototype=protoname Duplicate the quotas of the prototypical user specified for each user specified. This is the normal mechanism used to initialize quotas for groups of users. --- To configure quotas in postfix/dovecot environment, it seems that you need to use dovecot-lda plugin, and then my exact question is as follows: Is it possible to automatically run any commands or scripts in order to set a quota rule to $HOME/Maildir/* mailboxes when users receive an email for the first time? I just found the post-login service allows you to execute scripts after authentication in the following URL, but I have not found the exact way to make it. http://www.dovecot.org/list/dovecot/2009-November/044279.html Any comments/suggestions would be greatly appreciated. -- Masaharu Kawada

sieve_extprograms: how to filter original message twice?
by N0T3P4D 15 Jun '16

15 Jun '16

Hi, I use dovecot and sieve_extprograms to encrypt all incoming messages with the help of a Python script. Now, I want to process the _original_ message a second time. However, as expected, the second filter is applied to the already filtered message. For reference, here's a copy of the sieve script in question: if address :matches "To" "X(a)Y.Z" { fileinto "INBOX"; filter "gpgit.py" ["X(a)Y.Z", "--encrypt"]; fileinto "encrypted"; filter "gpgit.py" ["X(a)Y.Z", "--wrap"]; # Should be applied to the original message but uses the result of the first filter command fileinto "wrapped"; stop; } Does anyone have an idea how to modify the script to get the intended result? Please cc me, as I'm not subscribed. Thanks for your help Jeremias

Building Dovecot 2.2.24 GIT HEAD version
by Juan C. Blanco 15 Jun '16

15 Jun '16

Hello, I'm testing the last GIT (master-2.2) versión of dovecot 2.2 but I'm not able to build new rpm packages with our SPEC file on Centos 5.11. The problem seems to be with a new lib-dcrypt library, the file "src/lib-dcrypt/dcrypt-openssl.c" includes the file "openssl/ec.h" but the OpenSSL devel package included in Centos 5.11 is openssl-devel-0.9.8e-40.el5_11 that not contains the "openssl/ec.h" file I don't know if the next dovecot 2.2 release (derived from 2.2.24 GIT) will not be compatible with Centos 5.11 or if it will be necesary to install some optional openssl packages.

Upgrade to 2.2.9 breaks sasl auth
by Paul 15 Jun '16

15 Jun '16

Hi This is my 1st time here so please be gentle. I have encountered one problem since upgrading from 2.0.19 to 2.2.9 which has me beat. The system provides sasl auth services via inet to a postfix 2.11 system. Since the upgrade postfix complains of no sasl methods available. The same dovecot configuration is used on both versions. Now I get these results looking at the inet connection Version 2.0.19 root@larch:~# telnet 192.168.3.15 12345 Trying 192.168.3.15... Connected to 192.168.3.15. Escape character is '^]'.

Connected to 192.168.3.112. Escape character is '^]'. VERSION 1 1 SPID 5300 Seems be something lacking in the response from 2.2.9 that fits the "no sasl methods" response from postfix I believe I should supply root@larchvm:/etc/dovecot-sasl# dovecot -n -c dovecot.conf # 2.2.9: dovecot.conf # OS: Linux 3.13.0-88-generic i686 Ubuntu 14.04.4 LTS auth_mechanisms = plain login cram-md5 auth_verbose_passwords = plain base_dir = /var/run/dovecot-sasl/ disable_plaintext_auth = no instance_name = sasl mail_chroot = /chroot/mail mail_location = maildir:~/Maildir mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacati on subaddress comparator-i;ascii-numeric relational regex imap4flags copy includ e variables body enotify environment mailbox date ihave namespace { inbox = yes location = prefix = INBOX. type = private } passdb { args = /etc/dovecot-sasl/dovecot-sqlmd5.conf driver = sql } plugin { deleted_to_trash_folder = Trash quota = maildir:User quota quota:noenforcing quota_rule = Trash:ignore sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { inet_listener auth-userdb { address = 192.168.3.112 port = 12345 ssl = yes } unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { mode = 0600 } } service imap-login { inet_listener imap { address = 213.210.16.65 port = 143 } inet_listener imaps { address = 213.210.16.65 port = 993 ssl = yes } } service managesieve-login { inet_listener sieve { address = 213.210.16.65 port = 4190 } } ssl_cert = </etc/ssl/certs/pe.pem ssl_key = </etc/ssl/private/pe.pem userdb { args = /etc/dovecot-sasl/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota deleted_to_trash } Any help or suggestion warmly welcomed

shutdown_clients has no effect on doveadm stop
by Roland Rosenfeld 14 Jun '16

14 Jun '16

I try to restart dovecot 2.2.24 (for changing limits) without killing all IMAP and POP3 sessions. dovecot(1) tells me: When shutdown_clients is set to no, existing sessions will continue to use the old settings, after a dovecot reload. Also all sessions will keep alive after a dovecot stop. By default all active sessions will be shut down. According to my "dovecot -n" (see below), I have set "shutdown_clients=no", so "doveadm stop" should keep my open sessions. But if I try this out with a simple telnet to port 143 during "doveadm stop", I see the following: $ telnet imap 143 Connected to imap. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. a login user(a)example.com XXXXX a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE QUOTA ACL RIGHTS=texk] Logged in * BYE Server shutting down. Connection closed by foreign host. The "BYE Server shutting down." happens exactly at the time, when I press return after "doveadm stop", "systemctl stop dovecot", or "systemctl restart dovecot" in the other shell. Only "systemctl reload dovecot" keeps the open sessions healthy. So it seems that either the man page is wrong, or shutdown_clients=no has no effect after dovecot stop...

Alternate Storage and quota limits
by mailing lists 14 Jun '16

Hi all, is there any way of exclude messages storaged in alternate storage (*dbox mailbox format) from being included in the quota usage? I think this is not possible but let me ask.

Advice on once a day message delivery setup
by KT Walrus 14 Jun '16

14 Jun '16

I’m adding once a day mail delivery to my site. Messages are marked by the sender as “overnight” or “once a week” delivery. The way I’m planning on implementing this is to queue messages until midnight in a MySQL database. Each mailbox will be kept in two Dovecot mailstores. The first mailstore will give the users IMAP access to their mailbox. A second mailstore will hold the next day’s new messages. At midnight, a cron job runs to send messages in the MySQL database out to the second mailstore. Then, at 6am, a second cron job will run to sync the two mailstores using doveadm sync. What I am expecting to happen is that during the day, notification messages (from the site) may be delivered to the first mailstore (the one providing IMAP access to the user) but no messages from other users sent during the day will come until after 6am the next day. Each time the user submits a new message, a notification message is sent back to the sender with a link for editing the queued message in the MySQL database and an indication of when it is scheduled for delivery. I am kind of assuming that the morning sync process is fast enough so it can easily complete before noon (in 6 hours) even if I end up having lots of mailboxes on each fully loaded Dovecot server. Is the doveadm sync process reliable and efficient enough for this type of “once a day” morning new message mail delivery? Or, should I just start delivering messages after midnight and not bother with the second mailstore and subsequent sync? Just looking for any advice… I kind of like the idea of modeling my mail service after the US Post Office where the mailman delivers new mail once a day rather than like Twitter/Facebook where messages are posted in real time to encourage users to monitor their boxes throughout the day.
