FW: error using default_fields in passwd-file

I didn't see a response. Sending again and adding doveconf -n output. ---- I'm trying to put virtual user mail in: /var/vmail/<domain>/<user-local-part> I tried setting the home field in the userdb to /var/vmail/%d/%n But apparently variable expansion doesn't happen in the userdb because the Dovecot LDA created the literal directory /var/vmail/%d/%n/Maildir So then I tried to use default_fields as shown here: http://wiki2.dovecot.org/AuthDatabase/PasswdFile So I tried: userdb { driver = passwd-file args = username_format=%n /etc/dovecot/auth.d/%d/passwd default_fields = home=/var/vmail/%d/%n } But when I reload doveadm I get: doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 87: Unknown setting: default_fields I tried override_fields: userdb { driver = passwd-file args = username_format=%n /etc/dovecot/auth.d/%d/passwd override_fields = home=/var/vmail/%d/%n } And I get the same type of error: doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 87: Unknown setting: override_fields What gives?

fts lucene crashes in 2.2.24

Hi, I've just enabled FTS via Lucene on my Dovecot 2.2.24 installation but I see the indexer crashing ?always?.

newbie userdb lookup problem
by Michael Fox 23 Jun '16

23 Jun '16

I'm new to Dovecot and I'm having trouble getting basic, flat file userdb lookups to work. This must have been asked before, but if so, I can't find it. I'm following the basic setup here: http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall with a few minor differences. Output of doveconf -n is below, as well as relevant entries from postfix main.cf and master.cf. When I send a message to a virtual user that will be handled by Dovecot, Postfix hands it off to Dovecot LDA. But I get the following error in the log: Jun 22 20:53:33 xxxxx dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755) /var/run/dovecot/ is indeed owned by root:root with 0755 permissions. The actual passwd file used for userdb/passdb is currently owned by root:vmail with 0640 permissions. I read http://wiki2.dovecot.org/UserIds but I just don't understand the section on "Authentication process user". It's very vague. It doesn't explain which service is used for which circumstances or how to correlate the userdb/passdb file permissions with the service user/group settings for best security. The http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall link mentions nothing about having to modify the auth or auth-worker services. And the http://wiki2.dovecot.org/HowTo/VirtualUserFlatFilesPostfix page mentions a new "doveauth" user which isn't described elsewhere and sets service auth to user postfix and group postfix, something not mentioned anywhere else. /etc/doveconf/10-master.conf says that the service auth socket is typically readable only by root. Uhm. OK. Well, my passwd file is owned by root. I don't know how that relates to the socket. So I don't understand the problem. Bottom line, each information source seems to say something completely different. I can't correlate the information in the above sources into any actionable result. Questions: Basically, can someone please explain how the permissions for userdb and passdb lookup work (i.e. file permissions vs. service permissions)? What's the best solution to solve the above problem permission problem in the most secure way? Adjust the config of service auth? If so, how and why? Or adjust my passwd file ownership? If so, how and why? I'm really trying to understand the why, not just the what. Thanks much.

Pluggable SNI?
by Felipe Gasper 23 Jun '16

23 Jun '16

Hello, How feasible would it be to have a “pluggable” Dovecot setup that would permit arbitrary logic for fetching TLS/SNI certificates and key, rather than having to hard-code each domain’s resources in a configuration file? A couple scenarios that I envision such a framework being able to accommodate: 1) An internal TLS service that accepts queries via a UNIX socket by domain name and returns certificate/key. 2) A directory where these resources are stored, indexed by domain name. Thank you! -FG

Storage upgrade maildir suggestions?
by Götz Reinicke - IT Koordinator 22 Jun '16

22 Jun '16

Hi, we start to run out of diskspace soon as our users start to keep mails for longer time periods. That's fine, but space consuming. The maildirs are about 1 TB in total, and not long ago we enabled zlib which is very nice. Now I have some thoughts about the next steps: a) Migrating the whole system to a new server with more storage? b) Install a virtual server for the mailsystem and an extra storage system may be NFS? c) Stay with the current server and move all mails to a bigger NFS storage. The last option c) would be the most easy one for me as I currently have NFS space. Any thoughts? Hints regarding the NFS storage? Pros Cons? I have seen the dovecot wiki on NFS already and for now we will stay with one single dovecot server. Thanks and regards . Götz

autocreate: We need "auto=init"!
by Peer Heinlein 22 Jun '16

22 Jun '16

There had been several discussions about the common problem, that there's need for a autocreate-function that creates mailboxes ONLY for new users that had never been logged in before. The reason: Existing users already HAVE "special folders" with localized names. Creating "standard names" at every login will produce confusion, because then they have multiple Sent-Folders and aren't be able to delete them, because they'll always be recreated. I would love to have: 1) auto = init Create the folders ONLY if the whole Storage-Folder (e.g.: ~/Maildir or e.g. `/mdbox) is create (=creation of the INBOX itself). Don't create any folder if the main INBOX already exists. Since there has to be a hook to autoreate a non-existing INBOX it should be able to use this action to also create the folders with auto=init at the same time. 2) auto by type Create that "special folder" only if no other special folder exists. If we have "Sent" and "Sent Items" we could set "mailbox Sent { auto=create-by-type }" so this folder will only be created if no other "\Sent" folder (like "Sent Items") already exists. Dovecot could make sure, that there is AT LEAST ONE or JUST ONE of the special folder \Draft, \Trahs, \Sent. Personally: I would prefere (1) -- and that's what several users already requestet here at the list in the last two years. Function (1) is the only way to change the behavior on a complex, already running system with existing users. That's the way how to introduce new folders for new users without breaking everything for existing users. Any chance for us the get this?

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 ?

archive all saved IMAP messages
by KT Walrus 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

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

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

Hi! Is there a reason the email filter sieve can only activate one single script? > list "mailinglists.sieve" "spam.sieve" ACTIVE > activate mailinglists.sieve > list "mailinglists.sieve" ACTIVE "spam.sieve" > I can't see the logic here ... I am doing something wrong? Aaron

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

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
