[Dovecot] Sieve/pigeonhole with Exim and Dovecot LDA
by Sebastian Arcus 30 May '13

30 May '13

I am trying to configure my Dovecot installation to provide Vacation/Out-of-the-office emails using the Sieve plugin. My setup is a little bit peculiar: Internet Internet | ^ V | Provider's POP3 server Provider's SMTP server | ^ V | -------------- getmail | my server | | V | Dovecot LDA ---> Sieve/vacation -----> Exim | V Dovecot my server --------------- Sorry for the ASCII art above - I thought it would be quicker than trying to explain. The trouble I'm having is getting the Dovecot LDA to send successfully through the local exim instance out-of-office replies back to the provider's smtp server - when receiving fresh email from the provider (through getmail). Dovecot LDA tries to send the replies - but Exim freezes them because they don't contain the sender data in the format Exim wants it. Exim can either receive sender info: 1. On the command line, after the "-f" command line switch (but only when called by root or other users passed under "trusted_users" in exim.conf). 2. In the header of the email - in the "From:" field - but only, apparently, if it was called with the "-t" switch. Full exim command line documentation here: http://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_exim_comman… I can't figure out what command line options the Dovecot LDA is using when calling exim. I also couldn't find a way to get Dovecot LDA to pass extra options to exim, when trying to send email. The exim log has the following: 2013-05-20 15:35:15 1UeRBB-0001xc-Ar Frozen (message created with -f <>) I've inspected the frozen message - and it has the correct sender in the "From:" field - but it seems that exim isn't using that, because it wasn't called with the "-t" option. In dovecot.conf, I have the following for Dovecot LDA and sieve: protocols = imap sieve protocol lda { log_path = /var/log/dovecot/dovecot-deliver.log info_log_path = /var/log/dovecot/dovecot-deliver-info.log postmaster_address = admin(a)mydomain.co.uk hostname = mydomain.co.uk mail_plugins = sieve mail_plugin_dir = /usr/lib/dovecot sendmail_path = /usr/sbin/exim } service managesieve-login { inet_listener sieve { port = 4190 } } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } Dovecot LDA is called by getmail using the vmail user - and using the same user it is trying to call exim to deliver the out-of-office replies. I'm using Dovecot 2.2.1 with pigeonhole 0.4.0. I can post the rest of dovecot.conf if it would help. I've read through the stuff at dovecot.org - but all the Dovecot LDA and exim info refers to Exim passing email to Dovecot using Dovecot LDA - not Dovecot LDA sending email out using Exim.

[Dovecot] Perfect LDAP tree

Hello everybody and Timo. I have the next problem. With LDAP tree like ou=mail | - dc=example1.com,ou=Mail | - mail=box1(a)example1.com,dc=example1.com,ou=Mail | - mail=box2(a)example1.com,dc=example1.com,ou=Mail … | - dc=example2.com,ou=Mail | - mail=box1(a)example2.com,dc=example2.com,ou=Mail | - mail=box2(a)example2.com,dc=example2.com,ou=Mail … and settings in dovecot configuration files auth_bind = yes auth_bind_userdn = mail=%u,dc=%d,ou=mail base = ou=mail user_attrs = \ =home=/var/vmail/%Ld/%Ln, \ =quota_rule=*:storage=%{ldap:mailQuota}M user_filter = (&(objectClass=mailUser)(accountStatus=active)(mail=%u)) pass_attrs = \ =user=%{ldap:mail}, \ =proxy_maybe=yes, \ =host=%{ldap:mailHost}, \ =userdb_home=/var/vmail/%Ld/%Ln, \ =userdb_quota_rule=*:storage=%{ldap:mailQuota}M pass_filter = (&(objectClass=mailUser)(accountStatus=active)(mail=%u)) iterate_attrs = mail=user iterate_filter = (&(objectClass=mailUser)(accountStatus=active)) all works fine. But my soul of perfectionist do not like this configuration because in every mailbox record duplicated information about domain: mail=box1(a)example2.com and dc=example2.com I want to set next LDAP tree ou=mail | - dc=example1.com,ou=Mail | - mail=box1,dc=example1.com,ou=Mail | - mail=box2,dc=example1.com,ou=Mail … | - dc=example2.com,ou=Mail | - mail=box1,dc=example2.com,ou=Mail | - mail=box2,dc=example2.com,ou=Mail … but I don't understand how to limit query to box1(a)example1.com in dc=example1.com,ou=mail without using base=dc=%d,ou=Clients,o=m and how to get working iterate query for all boxes to get list box1(a)example1.com box2(a)example1.com box1(a)example2.com box2(a)example2.com in some command like doveadm quota recalc -A. Is it possible? How to take it?

While it's often convenient to make a distinction between 'system' and 'virtual' users, Dovecot doesn't actually know the difference. It just looks users up in the passdb and userdb you have configured. This means it's perfectly straightforward to do a completely 'virtual user' setup, and then change the passdb to 'pam', which will let the users log in with their ordinary Unix password. To allow users to log in with just a username, all you need to do is make sure the users in the userdb and passdb are listed that way. Userdb passwd and passdb pam naturally are, but there's nothing to stop you using other userdbs if you want to. The only trick here is that if you're using LDA/LMTP then incoming deliveries will (or, at least, usually should) be addressed to a full email address, so you need auth_username_format to trim that back to a username. I don't know anything about Usermin, but if it is trying to set up traditional procmail filtering and vacation(1), you may be in trouble. Or, at least, you may have to give up on using Dovecot to deliver the mail and let Postfix's local(8) and procmail deliver it into maildirs themselves. If you're happy with this, this isn't a problem for Dovecot, but it might be better to go with Sieve filtering instead. Sieve is a newish mail filtering language, designed primarily to be safe (procmail has a nasty habit of letting users run arbitrary programs). Dovecot's LDA has a pretty complete sieve implementation called Pigeonhole (you may need to install it separately), which also supports a protocol called ManageSieve designed for uploading sieve scripts remotely. There are plugins for some webmail systems (and some desktop mail clients, for that matter) which let the user edit their filters in a gooey way; this includes setting up vacation messages. I use Roundcube webmail for this purpose; it also has a perfectly good PAM password- changing plugin. Ben

[Dovecot] dsync
by Erik Colson 29 May '13

29 May '13

Hi Is dovecot dsync considered an alternative to offlineimap (or others) when both distant and local are IMAP dovecot servers ? I used offlineimap for this, but somehow offlineimap got messed up (more than once, but without me able to explain how it happened). So I'm considering dsync for this purpose... Thanks! -- erik

[Dovecot] Enable IMAP only for certain users/IP
by Simone Marx :: Edinet Srl 29 May '13

29 May '13

Hi, I'm trying to config dovecot to enable IMAP protocol only for certain IPs and users. The logical steps I've followed are: 1. If a user is trying to login from an IP that I've authorized ( listed in a file) the request is authorized. 2. If not, if the user is listed in a second file the request is authorized. 3. If also this check fails the request is rejected. I'm using PAM for passdb and a passwd-file for userdb: passdb { driver = pam args = session=yes failure_show_msg=yes max_requests=16 cache_key=%u%r%l dovecot-%s } userdb { driver = passwd-file args = /etc/passwd-dovecot } In /etc/pam.d/ there are two files: dovecot-pop3 dovecot-imap dovecot-pop3: #%PAM-1.0 @include common-auth @include common-account @include common-session (for this protocol everything works fine, I don't want to limit it.) dovecot-imap: #%PAM-1.0 @include common-auth auth sufficient pam_listfile.so item=rhost sense=allow file=/etc/dovecot/imaphosts onerr=fail auth required pam_listfile.so item=user sense=allow file=/etc/dovecot/imapusers onerr=fail @include common-account @include common-session If I'm not wrong, once the user is authenticated, PAM checks if the remote IP address is in imaphosts; if it's true, it returns PAM_SUCCESS and stops the execution of the auth block, else if it's false, PAM executes the next line, verifying the presence of the username in imapusers file; if found, then return PAM_SUCCESS, else fail. If this can work, I've a problem with pam_listfile.so and IP addresses: I want to do something smarter than specifying 2^11 IP addresses instead a /21 or IP/netmask Are there alternatives for doing it better? Thanks. Sincerely, Simone Marx.

[Dovecot] Dovecot 2.1.7-7 only allow localhost access to IMAP and POP3
by Torben Schou Jensen 29 May '13

29 May '13

Recently I have upgraded my server to Debian 7. Debian have now removed uw-imapd and suggest using dovecot instead. Debian include dovecot version 2.1.7-7. On http://www.debian-administration.org/articles/275 and http://www.debian-administration.org/articles/200 I can read how to setup older version of dovecot with SquirrelMail. They recommend to use uncrypted IMAP when SquirrelMail is on same server. What I would like to support is then imap, imaps, pop3 and pop3s. imaps and pop3s for external users. imap and pop3 only open for localhost, that is SquirrelMail on same machine. With dovecot 1 you could restrict access using "imap_listen = localhost" How do I make the same restriction with localhost on dovecot 2 ??? Brgds Torben

Hello, So I am currently running dovecot 1.2.11 on Debian 5 for our production email systems. We just deployed some new Debian 7 servers and we will be upgrading to the latest dovecot version. I've been reading the docs, but I wanted to heard some feedback on the import of all my current email into the new installation. We have 320GB worth of email. Any gotchas I should be prepared for? Any complications I should be aware of when importing all these data? Any thoughts would be appreciated.

[Dovecot] system account delivery userdb authentication
by Yann Shukor 29 May '13

29 May '13

Hi I have a remaining issue with a mail server setup. Composed of Postfix and Dovecot it is is a 'local' mail server At first I relied upon Mysql to store the various parameters, and then switched to a flat file approach I also initially set the server up to handle virtual users, but then I realized that it was destined to manage local system accounts only. So I reconfigured it accordingly Relying on system accounts for authentication means that the domain name component is absent from the username (as opposed to virtual user identifiers) This caused me some difficulty at first with roundcube, but I was able to get around it through a manual adjustment in Mysql The remaining aspect that isn't working is the delivery of emails. The entry in master.cf for dovecot looks looks this: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deli ver -d ${recipient} The problem is that the recipient equates to the users email address, which can't in fact be used for authentication purposes with system accounts. I then tried replacing recipient with user: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -d ${user} There seems to be a rights issue because I get the following error: dovecot Fatal: setgid(100(users)) failed with euid=8(mail), gid=8(mail), egid=8(mail): Operation not permitted Any ideas ? thanks yann # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.7 ext4 log_timestamp: %d-%m-%Y %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/mail/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)holinice.com mail_plugins: sieve log_path: syslog_facility: mail auth default: mechanisms: plain login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: mail group: mail

[Dovecot] dovecot + virtio (9p2000.L) = errors

Hi! I hope someone knows more about the issues I've encountered in: Setup: I am running dovecot 2.1.7 on Debian Wheezy in a virtual machine (kvm-style qemu-kvm: host: ubuntu 13.04/1.4.0-dfsg-1expubuntu). The mail storage is a directory on the host machine mounted via virtfs (9p2000.L) on the guest. Furthermore ISPConfig is involved in that setup, but that should not make any significant difference at that point. Problem resolved: The problem is, that similar to nfs mmap() and dotlocking seem to fail - the mmap issue could be resolved by adding: mmap_disable=yes to dovecot.conf Problem remaining: Still the following errors remain, despite dotlock_use_excl=no May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/.quotausage.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: file dict commit: file_dotlock_open(/var/vmail/mydomain/test/.quotausage) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: file_dotlock_create(/var/vmail/mydomain/test/Maildir/dovecot-uidlist) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 27 12:54:52 host dovecot: imap(test@mydomain): Error: file_dotlock_create(/var/vmail/mydomain/test/Maildir/dovecot-uidlist) failed: No such file or directory The "failed" files are existing on that path - permissions for the configured "vmail" user and group exist (0600).

[Dovecot] UIDLs problem on migration to dovecot
by Oscar A. Jara 27 May '13

27 May '13

Hello list, I'm about to migrate from Courier 4.6 (POP and IMAP) to Dovecot 1.2. I am currently trying to match UIDLs of both servers to avoid redownload of mails but I could not success. I've already configured dovecot POP3 to format UIDLs like this: pop3_uidl_format = UID%u-%v I also executed the script 'courier-dovecot-migrate.pl' to do the migration in a couple of test accounts but the IDs don't match for all mails and the script didn't report any errors. I have production courier pop3 server running on port 110 and the new dovecot server running on another port. Here I paste some of the missmatches in one of the test accounts: 8827 UID9060-1259354075 | 8827 UID9041-1259354075 8828 UID9061-1259354075 | 8828 UID9023-1259354075 8829 UID9062-1259354075 | 8829 UID9067-1259354075 8830 UID9063-1259354075 | 8830 UID9064-1259354075 8831 UID9064-1259354075 | 8831 UID9043-1259354075 8832 UID9065-1259354075 | 8832 UID9061-1259354075 8833 UID9066-1259354075 | 8833 UID9025-1259354075 8834 UID9067-1259354075 | 8834 UID9047-1259354075 One thing that I don't know if is important is that I am using dovecot-lda since long ago, not courier lda. I don't know what I am missing here and I would appreciate some help.

[Dovecot] Problem with dsync replication : mails are not deleted correctly
by Nicolas ROCHE 27 May '13

27 May '13

Hello, I would like to configure a postfix / dovecot cluster based on ssh / dsync replication. I have two linux serveurs (Oracle RHEL 5 86_64) and I install both sides dovecot (V2.2.2+), postfix (2.10.0) and mysql (Ver 14.12 Distrib 5.0.77). I configured these servers in order to make them replicate, and I created some virtual users. I use some java code in order to send mail (with SMTP) and to get mail (with POP3). When the java code get a mail, it deletes it from mailbox (the flag "DELETED" is set to true). When I send a mail on server A, I can see the mail replicated on both servers A and B : a file containing the message data exists in /home/vmail/test03/new/ in both sides. When I get the mail from server A with my java POP3 client, all is OK : the mail is deleted on both servers A and B (no more file in /home/vmail/test03/new/). The problem is when I send a mail on server A and I get it from server B : I can get the mail, but the mail is not deleted from server B, and neither from server A. When I try a second time to get the mail on server B, then all becomes OK : the mail is deleted on both server A and B. I can reproduce the problem every time. Is it a known bug or not ? If yes, is there a patch ? If no, may the problem come from my config ? Regards, Nicolas.

[Dovecot] Upgrading 1.2 to 2.x
by Simon B 27 May '13

27 May '13

Hi In an unscheduled maintenance window next week, I will have the opportunity to upgrade to 2.x should I wish to do and provided I can get it working on stage first. My questions: I've seen a lot on the list about the rock-solidness of 1.2 but also some people saying that some versions of 2.x better than others. Is there a recommended version - I don't need bleeding edge, I'd prefer stability, or one most of you can agree on? What am I missing by not upgrading? A few months ago I tried to convert a Dovecot 1.2 config into 2.1 and wasn't very successful. Any tips on how to go about it? Thanks. Simon

[Dovecot] mixing virtual and system users
by Julien Beauviala 27 May '13

27 May '13

Hello all, I'm setting up a small mail server for aprox 20 users, and I'm trying to keep it really simple so I went the virtual users as text file way, following this page : http://lukas-schulze.de/2012/02/setup-postfix-and-dovecot-on-debian-squeeze… It seemed to work fine except for the 'system' users, and I am stumped by this. Basically the config does not 'see' /etc/aliases, so mail to root or mailman are 'Recipient address rejected: User unknown'. I've added the backup pam as explained by the following page* and tried many permutations in /etc/postfix/main.cf but still not good, systems users are rejected. Obviously something is amiss. * http://wiki2.dovecot.org/Authentication/MultipleDatabases If someone could point me in the right direction, that would be great.

Hi everyone, I would like to move my mails from ocfs2 to an NFS share. As the mountpoint and all folders and files belong to nobody/nogroup, dovecot is only able to access the mails if I give full access to "others". I don't like that. How do you NFS-using guys solve this problem? Regards Patrick

[Dovecot] Problems with Apple Mail: Enter Password for Account "..."
by Frank Röhm 26 May '13

26 May '13

Hello I have on Ubuntu 12.04 a postfix 2.9.3-2 mailserver with dovecot 2.0.19 I get email from my pc (thunderbird), my smartphone (k9mail) and my MacBook (Apple Mail 4.6 - 1085 on Mac OS 10.6.8) all with IMAP and SSL. All is working normally but sometimes I get an error message from my MacBook, which is irritating. It says this (more or less): "Enter Password for Account "..." The IMAP-Server "..." rejected the password for user "..." Enter your password again or cancel. ... o Remember this password in my keychain" The password was NOT wrong, but anyway, if reenter it, Apple Mail won't accept it, the message will come again and again. I guess that dovecot blocks apple mail maybe because the other two clients try to login at the same time? Is there any setting where I could adjust this blocking (if it is blocking) in dovecot? Only if this really is the reason. The issue is coming not regularily but when it comes, often for half an hour I cannot check mails for this account (other accounts on apple mail won't be touched). If I restart Apple Mail, the problem could be fixed, but maybe not. In the logfiles of Dovecot I don't find anything about this. Thank you and kind regards frank

[Dovecot] dovecot-sieve (pigeonhole) -- is is possible to "re-filter" INBOX when filters have been updated?
by Lev Serebryakov 25 May '13

25 May '13

Hello, Dovecot. I want to migrate to webmail (roundcube) over dovecot + sieve (pigeonhole). Now I'm using on-client (The Bat!) filters, but I need to have acccess to my mail everywhere, not only on my workstation. And I wonder, is here simple way to re-filter INBOX after sieve filters have been changed? Any offline (desktop) mail client could run new filters on old messages -- is here any way to do this with dovecot-sieve (pigeonhole)? I'm using postfix + dovecot LMTP to run sieve filters. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Virtual Servers, or different authentication setups.
by Joshua Gardner 25 May '13

25 May '13

I want to know if there is any virtual server functionality in Dovecot? I would like to have two separate configurations, that access the same email, running in the same Dovecot instance. They would bind different ports and/or IPs, but have different authentication settings. In particular, one would use a PLAIN password scheme, the other SSHA. How would I go about setting up these virtual servers? Or, would I have to run separate instances of Dovecot? If I do have to run separate instances, how do I keep them from interfering with eachother? -Josh

[Dovecot] Passwordless auth?
by Dan Mahoney, System Admin 25 May '13

25 May '13

Hey all, I'm in the process of writing some scripts which I want to be able to take actions on my local mailbox. (For example, to move a subset of messages to the trash over time, if unread for a week. To act on messages in my learn-spam folder and then delete them). What occured to me as being a Neat Idea is if Dovecot could honor ident (rfc1413) lookups, from trusted hosts (i.e. 127.0.0.1). In this way I get all the benefits of dovecot's indexing being updated and nice locking, but I don't have to leave my password laying around in a plaintext file. (Yes, this assumes I'm running a shell on the mail server. I'm not concerned about the same level of security when you could simply cat my mail spool). I'd definitely consider something like an SSH key with a forced command (I do see questions in the FAQ about making dovecot work over a socket connection), but that forgoes using standard imap clients. I could also create a dovecot-only user with my UID and no other login privileges, but I'd like this to "just work" for anyone. I don't know anything about if dovecot supports X509 auth, but this would require the client libraries to support such a thing, which not all do. I'd love to hear about any other ways people have thought about to do this. Any ideas? -Dan Mahoney -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------
