[Dovecot] Blocking auth services
by Peter Mogensen 15 Aug '11

15 Aug '11

Hi, I'm writing an passdb/userdb plugin to authenticate against an external daemon listening on a UNIX socket. The connection to the daemon is 1 request at a time and thus blocking (unlike passdb-ldap), but the daemon is preforking, so it can handle more connections at a time. I read from the Wiki: http://wiki2.dovecot.org/Design/AuthProcess * "The authentication may begin new authentication requests even before the existing ones are finished. ", and * "If the passdb uses connections to external services, it's preferred that they use non-blocking connections. Dovecot does this whenever possible (PostgreSQL and LDAP for example). If it's not possible, set blocking = TRUE. " ... which tells me to set the module as blocking and let more auth worker processes do the work - creating 1 daemon process for each auth worker process, I guess. But I also have the option, to let the passdb/userdb plugin maintain a pools of used/idle connections to the daemon and just pick a idle connection and moving it to the used pool on each auth_request. Which would save me the auth worker processes. Is there a preferred dovecot way? /Peter

[Dovecot] Parallel auth
by Bernhard Schmidt 15 Aug '11

15 Aug '11

Hello, we run a Dovecot 2.0.13 instance purely as SASL backend for Postfix, authenticating against a local passwd-file and our central LDAP database. # dovecot -n # 2.0.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32.36-0.5-default x86_64 SUSE Linux Enterprise Server 11 # (x86_64) auth_mechanisms = plain login auth_verbose = yes passdb { args = /etc/dovecot/dovecot-passwd driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap-simauth.conf.ext driver = ldap } protocols = none service auth { unix_listener /var/spool/postfix-postout/private/auth { group = postfix mode = 0660 user = postfix } } ssl = no There is only a single user in the passwd-file for monitoring. We monitor authentication delays for both this local user and one user from LDAP. Due to a firmware bug, our six-figures NAS causes extremely high LDAP delays (in the range of 20-60 seconds, instead of the usual 50ms) once an hour. The weird thing is, I also see these delays in the graph for the local user. Which got me thinking * are authentication requests handled serially by dovecot/auth? * any way to solve this situation for the local user (not to be blocked by the delayed LDAP query)? * any way to solve this situation for LDAP users? We could possibly do some loadbalancing if the auth-daemon opened several LDAP connections Thanks, Bernhard

Hi, I am working on a webmail project using dovecot as imap server and I would need to make a demo however I don't want to show all my emails addresses. So my question is knowing that I am using the maildir format, would it ne possible to do a kind of search and replace of all emails/cc/to and replace them by fake ones or will it break something like indexes ?

[Dovecot] $IP not getting set?
by A.L. 15 Aug '11

15 Aug '11

Using dovecot 2.0.13. I went to implement relay-ctrl per directions on the Wiki, and failed. After running it down, as best as I can determine, the problem is that the $IP variable is not getting set (and thus not re-set in the script wrapper). I plunked a "set >> debug" into the script, and the only env var's that are set are as listed below (slightly sanitized for public display). Anyone have any ideas? I have tried both the Wiki-way, and this way: http://dovecot.org/list/dovecot/2009-December/045139.html with identical results.

[Dovecot] shared mailboxes

Hi all, I've read all documentation that I could find, but I can not understand 2 simple things 1. How to create a public mailbox - with per user seen flag. In my configuration this flag is shared 2. How to share one user mailbox with other users and set up acl. In Cyrus it was very easy( cyradm sam mailbox user1 lrs or sam mailbox user2 all ). What way there is to do this in dovecot. It was no problem with shared mailboxes in cyrus, but I need maildir support.

[Dovecot] SQL passdb lookups not working
by Benjamin Montgomery 14 Aug '11

14 Aug '11

Hello everyone, I'm trying to make dovecot do user authentication against a SQL database. The passwords (managed by Django) are stored as salted SHA1 encoded in hex. I monkey patched Django's password method so that the password hash is made with <password><salt> (Django does <salt><password>, the patched method was verified to return same value as dovecotpw) and the passwords are stored in the database separately as the salted hash and the salt. When I query the values out of the database, I'm using MySQL's concat function to return the password as {SSHA.hex}<sha1 hash><salt>. Dovecot is not able to verify any passwords right now. I've scoured the wiki and I think my setup is correct...config info is below. Any advice on where to look for debugging or setup of my passwords would be appreciated! Ben dovecot-sql.conf: default_pass_scheme = SSHA.hex password_query = \ SELECT emailmanager_emailaddresses.account AS username, \ emailmanager_domain.name AS domain, \ CONCAT('{SSHA.hex}', \ emailmanager_userprofile.shadigest, \ emailmanager_userprofile.salt \ ) AS password \ FROM emailmanager_emailaddresses \ JOIN emailmanager_domain ON emailmanager_emailaddresses.id = emailmanager_domain.id \ JOIN emailmanager_userprofile ON emailmanager_emailaddresses.id = emailmanager_userprofile.id \ WHERE emailmanager_emailaddresses.account = '%n' \ AND emailmanager_domain.name = '%d'

[Dovecot] Clients can't retrieve new emails
by Jeff Van Epps 12 Aug '11

12 Aug '11

In a formerly working environment suddenly clients aren't notified of new emails and can't retrieve new emails. Server is Ubuntu 11.04 dovecot 1.2.15. Clients which fail are a Pre2 webOS 2.1 and TouchPad webOS 3.0 (those are OS versions, I don't know which particular flavor/version the IMAP clients are); there is also a Thunderbird 3.1.11 client on the same system as the server which works properly. The clients never report an error. I got as far as configuring rawlog: in: ~A2 NAMESPACE ~A3 SELECT "INBOX" ~A4 LIST "" * ~A5 UID STORE 0 +FLAGS.SILENT (\Seen) ~A6 UID STORE 0 +FLAGS.SILENT (\Seen) out: * OK [RAWLOG TIMESTAMP] 2011-08-01 08:28:33 ~A1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in * NAMESPACE (("" "/")) NIL NIL ~A2 OK Namespace completed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk Junk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk Junk \*)] Flags permitted. * 101 EXISTS * 0 RECENT * OK [UNSEEN 63] First unseen. * OK [UIDVALIDITY 1222650706] UIDs valid * OK [UIDNEXT 863] Predicted next UID * OK [HIGHESTMODSEQ 1903] Highest ~A3 OK [READ-WRITE] Select completed. * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "INBOX" ~A4 OK List completed. ~A5 BAD Error in IMAP command UID STORE: Invalid uidset ~A6 BAD Error in IMAP command UID STORE: Invalid uidset I've searched and read messages saying that there is no such thing as UID 0. Okay. Why are the clients suddenly trying to use it? Why doesn't the server just ignore it? (it seems like it may be terminating the connection) What can I do about it? (I'll nag HP about the client side but I don't expect quick action. The server on the other hand is in my house.) dovecot -n output: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-11-generic i686 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/lordbah.com.crt ssl_key_file: /etc/ssl/private/lordbah.com.key ssl_key_password: --redacted-- disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_process_per_connection: no login_processes_count: 5 login_max_processes_count: 20 verbose_proctitle: yes mail_privileged_group: mail mail_location: mbox:~*/mail:INBOX=/var/mail/*%u mail_debug: yes mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap imap_client_workarounds: tb-extra-mailbox-sep auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: passwd -- Jeff Van Epps

Hi guys, I setup a new box with Debian Squeeze 64bit and installed dovecot from the sources. However, I can't start dovecot or even use doveconf: root@imap01:~# doveconf -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-mail.conf line 111: Unknown setting: mail_uid Why is mail_uid and mail_gid an unknown setting? On my other box the configuration is identical (but Dovecot is upgraded from early 2.0.x versions to the current one) If I comment the mail_uid and mail_gid lines, I get another error: root@imap01:~# doveconf -n doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-master.conf line 17: Unknown setting: service doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-master.conf line 17: Unknown setting: service Everything I could find on Google are problems after upgrading from 1.x to 2.x What went wrong?

[Dovecot] Thunderbird Will Not Download Email Until Computer Is Rebooted
by Jay Welch 11 Aug '11

11 Aug '11

Hey Guys, Have any of you seen an issue with Thunderbird in which the computer has to be rebooted for email to be downloaded? I have been looking over the InterWebs and I cannot find anything. I can see new email on the server as well. Where would be a good place to start for troubleshooting this issue? Thanks

Is there a way to match the destination mailbox in a sieve script? The email comes in by dovecot-lda -d $user -m Sent Now the sieve script should somehow match the mailbox "Sent".

[Dovecot] mbox problems on CentOS 6

Hello, I migrated yesterday to Dovecot 2, and I managed to "convert" all the settings I had in dovecot.conf, but I run into a strange problem. I am curently using Dovecot 2.0.13 and bellow is my dovecot.conf current content: # 2.0.13: //etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.29.1.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) ext4 auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 901 last_valid_uid = 901 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = IMAP/POP3 server ready. mail_access_groups = mail mail_debug = yes mail_location = mbox:/vmail/%d/%n:INDEX=/var/indexes/%u mail_max_userip_connections = 16 mail_privileged_group = mail passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocols = imap pop3 service auth { unix_listener auth-userdb { mode = 0600 } user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } } service imap { process_limit = 16 } service pop3-login { inet_listener pop3 { port = 110 } } service pop3 { process_limit = 16 } ssl = no userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } I am running along with Dovecot, Postfix and MySQL - oh SASL is of course installed as I want to make use of user auth.

Refer to server log for more information. Connection closed by foreign host. I activated debug and looked in the dovecot logs and here is the most intriguing part I found: auth: Info: mysql(localhost): Connected to database postfix imap-login: Info: Login: user=<contact(a)mydomain.com>, method=PLAIN, rip=::1, lip=::1, mpid=5821, secured imap: Debug: Added userdb setting: mail=maildir:/vmail/mydomain.com/contact imap: Debug: Added userdb setting: plugin/quota=dirsize:storage=0 imap(contact(a)mydomain.com): Debug: Effective uid=901, gid=12, home=/vmail/mydomain.com/contact imap(contact(a)mydomain.com): Error: user contact(a)mydomain.com: Initialization failed: Initializing mail storage from mail_location setting failed: Unknown mail storage driver maildir imap(contact(a)mydomain.com): Error: Invalid user settings. Refer to server log for more information. I double checked paths - all is ok - postfix is actually receiving and saving in that /vmail... folder # uid=901 coresponds to <vmail> user # gid=12 corresponds to <mail> group # rights on /vmail are vmail.mail I think there is actually a problem with mail_location - but I couldnt solve it at all. If anyone can help me with this - please do guys. I googled those terms and found nothing, so this is my last resort, I tried solving this in the last 36hrs but nothing so far. Thanks to anyone who can assist me.

[Dovecot] Dovecot quota dict
by Juan Bernhard 10 Aug '11

10 Aug '11

Hi, Im using dovecot with maildir++ quota and I have this problem, maybe some of you already solve this and can helpme. I want to use some flat file to tell exim and dovecot the quota limit for each user, i tried to work with exim and maildirsize file, but exim just ignores the limits there. I need a way (a really simple one, i dont want to create a database or an ldap server just for this) to tell exim and dovecot to lookup some file to get the quota limits. I know how to doit with exim, now i need to know how to tell dovecot to read the quota limits from this file. I know that dovecot can read the quota limit from the userdb, but im using pam and i dont want to change the entire auth schema. Can I configure dovecot to get the quota limit from a file using pam as userdb?

Cause 8 The BlackBerry Internet Service downloads any email message with an email message UID that it did not find during the previous connection. If the email message UIDs are changed by the messaging server, duplicate email messages are received. This behavior also applies to any email message that has a blank UID. Resolution 8 To resolve this issue, complete one of the following procedures. Make sure that the message UIDs of email messages on the integrated account messaging server do not change or that email messages are not added back to the inbox of the associated account. Ask your administrator if the message UIDs are changing. In the case of an email message that has a blank UID, have your administrator remove the email message from the email server to prevent it from being delivered repeatedly. Delete email messages from the BlackBerry smartphone using the Mailbox & Handheld setting (email messages will be deleted from the associated email account messaging server and will not be retrieved again by the BlackBerry Internet Service).

[Dovecot] authentication via LDAP
by Gerardo Herzig 09 Aug '11

09 Aug '11

Hi all. I have a couple of questions. ANY of those will solve mi situation. 1) 'Complex' LDAP validation: I need to validate a user in the 2 step authentication / authorizacion mech. The 'users' (with the password) are in ou=Person,o=Work the group which contains the mail users is in cn=MailUsers,ou=Groups,o=Work Can dovecot make such a thing? Cause im not shure if i can make this in a single ldap filter. 2) If not... 2.1) Does dovecot accept more than 1 rule for authenticating? 2.2) Does dovecot accept an arbitrary program for authentication? Well, that's all for now. Thanks! Gerardo

[Dovecot] mail delivery location wrong
by Firma Averlon 09 Aug '11

09 Aug '11

Hi, thanks for offering the oportunity to place a question here. I am now already working since a week to get postfix and dovecot working on a ubuntu 11.04 server. Hard task. First step was naturally to get familiar with the idea behind the archtitecture. I have come very far, but the "last dirty mile" is probably the hardest. My architecture: Postfix Dovecot OpenLDAP Thunderbird as client with pop3 I can meanwhile send e-mails and open my mailbox in thunderbird (not receiving mails so far). The reason why not receiving e-Mails is simply: When sending the mails they are stored in a different directory as where dovecot will look for them !!!! Error message from log: Aug 8 14:09:01 server dovecot: deliver(vmail): maildir: data=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir: data=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir++: root=/home/vmail//vmail/Maildir, index=, control=, inbox=/home/vmail//vmail/Maildir Aug 8 14:09:01 server dovecot: deliver(vmail): maildir++: root=/home/vmail//vmail/Maildir, index=, control=, inbox=/home/vmail//vmail/Maildir What you immediatly see: "vmail//vmail" Although, when authenticating, the result is: Aug 8 14:06:30 server dovecot: auth(default): master out: USER#0113#011userxxx@av.loc#011gid=5000#011home=/home/userxxx#011uid=5000#011mail=/home/vmail/av.loc/userxxx/Maildir/ The following settings are in place: main.cf of postfix: virtual_mailbox_domains = /etc/postfix/vhosts virtual_mailbox_base = /home/vmail virtual_mailbox_maps = ldap:/etc/postfix/ldap-virtual.cf virtual_minimum_uid = 1000 virtual_uid_maps = static:5000 virtual_gid_maps = static:5000 virtual_transport = dovecot mailbox_command = /usr/lib/dovecot/deliver beside others. master.cf of postfix dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -a ${recipient} dovecot.conf sendmail_path = /usr/sbin/sendmail mail_location = maildir:/home/vmail/%d/%n/Maildir beside others. I guess, these are the ones influencing where to store the mail and pick it up. A list of the related filesystem: /home/vmail/ drwx-w--w- 4 vmail vmail 4096 2011-08-08 08:56 av.loc/ drwx------ 3 vmail vmail 4096 2011-08-08 09:42 vmail/ Wher you can see, the structure according "mail_location" parameter of dovecot.conf does show effect, but the mails are stored in /home/vmail//vmail.....". The whole bunch of documentation I have read meanwhile makes my head circle around. You could hopefully give me some help. -- Mit freundlichen Grüßen / Kind Regards Hr. Karl-Heinz Fischbach

[Dovecot] How to make dovecot-lda/deliver mark a message as seen
by Stefan Piegsa 08 Aug '11

08 Aug '11

Hello everybody, I am using dovecot 2.0.13 and have a special case here in which I want a mail that is delivered locally with dovecot-lda to be marked as "seen". In dovecot 1.1.7 I succeeded to achive this, by modifing deliver.c so that upon adding a -S switch to the command arguments, the flag MAIL_SEEN was added to the call of mailbox_copy(). This seemed to work pretty good. With the new version, i tried to do something similar by selectively adding mail_update_flags(ctx.src_mail, MODIFY_ADD, MAIL_SEEN); just before the call of mail_deliver(), whenever the -S argument is given. But this does not work. What is wrong? Is there a better way to set MAIL_SEEN for a locally delivered mail? I would prefer a method that does not require to mess around in the dovecot sources. :-) Thanks in advance & Best Regards, Stefan

[Dovecot] Dovecot + LDAP login issues
by ml lists 08 Aug '11

08 Aug '11

Morning all, I've managed to work my self into a corner and hoping someone can help me out I have OpenLDAP and Dovecot installed based on the following documents: https://help.ubuntu.com/community/DovecotLDAP https://help.ubuntu.com/community/OpenLDAPServer When Dovecot is set up to log in without using LDAP, connections work fine. However as soon as I change the dovecot.conf to use ldap I get the following error when trying to log in: error in syslog: dovecot: auth(default): ldap(myuser,10.10.10.10): invalid credentials (given password: myuserpasswd) dovecot: auth(default): client out: FAIL#0112#011user=myuser I have checked via phpLDAPadmin that the password I am entering matches what is in the database, so from what I can see the issue lies in how Dovecot is passing the password to openLDAP, though I may be way off base here. No special characters in the passphrase other than spaces. Would anyone be able to shed some light on this?
