[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] trash plugin not doing it's job

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated. Thanks, Jeff dovecot -n provides the following: [root@xyzzy conf.d]# more /tmp/dovecot.changes # 2.0.21: /etc/dovecot/dovecot.conf # OS: Linux 3.4.11-1.fc16.x86_64 x86_64 Fedora release 16 (Verne) mail_debug = yes mail_location = mbox:~/mail:INBOX=~/mbox mail_plugins = " zlib" mbox_write_locks = fcntl namespace default { inbox = yes location = prefix = separator = / } namespace snarf { hidden = yes list = no location = mbox:/run/dovecot/empty:INBOX=/var/spool/mail/%u prefix = /snarf separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename snarf = = /snarf/INBOX } service imap-login { inet_listener imap { address = localhost } } service pop3-login { inet_listener pop3 { address = localhost } } ssl_cert = </etc/pki/tls/certs/XYZZY.pem ssl_key = </etc/pki/tls/certs/XYZZY.pem userdb { driver = passwd } protocol imap { mail_plugins = " zlib imap_zlib snarf" } and the logs (in debug) show the following: Oct 20 21:29:45 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19627, TLS Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt= Oct 20 21:29:46 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19629, TLS Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt=

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?

[Dovecot] mail open slowly
by Bernics Gábor | Penta Unió Zrt. 29 Oct '12

29 Oct '12

Hello, I have a dovecot IMAP server (relative small hardware: HP Microserver with 6 Gbyte RAM, linux soft RAID1 with 2x 7200 SATA disk) with 100 Gbyte maildirs. Server works fine but sometimes I can open mails slowly (5-10 sec), typical with new mails. It's intresting when I open an another old mail (with 0 sec wait), after new mail open quickly. Is it dovecot mail indexes or I/O problem? Load and CPU use is small typical 0.10, 10%, I see small IO wait. Debian 6.0, Dovecot 1.2.15, fsync and nmap is disable Best Regards, Gabor

Hello everybody, As explained in the topic, i have troubles with authentication of my users. First of all, sorry for my poor english... I'm running dovecot v1.2.15 on a Debian 6 64bits server up to date. My users database is an Active Directory 2003 (it's important to know that because Active Directory can't retrieve users passwords, you have to bind LDAP with a domain administrator). So, i'm using userdb ldap for authenticated my users and it works ! BUT... When an user having a password with special characters like " ² ° § µ à é è ç à â ê î ô û ù ä ë ï ö ü ", authentication does not work. And in my log file : MY_SERVER | mail/info | dovecot | 2012/08/27 10:42:14 | auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.

[Dovecot] Problem with sieve. dovecot 2.0.17
by Eliezer Croitoru 28 Oct '12

28 Oct '12

Since I have lots of filtering rules in thunderbird I was thinking of using sieve instead. I want to filter incoming mail into subdirectories. like "from" store at folder "old". the script is: require ["fileinto", "envelope"]; if envelope :is "from" "eliezer(a)test.dom" { fileinto "old"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } the result is that the mail is stored in two folders instead of just one, INBOX and old. the logs shows: Oct 23 17:12:26 lda(eliezer(a)ngtech.co.il): Debug: sieve: executing script from /home/vmail/domain/eliezer/home/.dovecot.svbin Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'INBOX' Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'old' from unknown reason(or I didnt understood how sieve works?) plugin section from dovecot -n plugin { ... sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.debug +imapflags +relational +comparator-i;ascii-numeric } Thanks, Eliezer

[Dovecot] How to activate antispam plugin

Hello, I'm using dovecot 2.1.7 from the Debian backports package and I'm trying to get working the antispam plugin with dspam. I have followed the documentation http://wiki2.dovecot.org/Plugins/Antispam but it does not seem to work. The /var/log/dspam folder is empty even after I put mail in the Spam folder. How can I see if the plugin is working and what config option am I missing ? Thank in advance for your help. Here is my config from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-xenU-6887-i386 i686 Debian 6.0.6 mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = prefix = } passdb { driver = pam } plugin { antispam_backend = dspam antispam_dspam_args = --mode=teft;--deliver=;--user;%u antispam_dspam_binary = /usr/bin/dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_spam = Spam antispam_trash = trash;Corbeille;Trash;Deleted Items; Deleted Messages sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = antispam } -- Xavier Claude claude.xavier(a)gmail.com

[Dovecot] Locking /var/mail/user issue with postfix and dovecot
by Robert JR 27 Oct '12

27 Oct '12

Hello, I have a question regarding mailbox locking and hope any one can help me to better understanding the locking of mbox My Postfix lock option is fcntl dotlock mailbox_delivery_lock = fcntl, dotlock virtual_mailbox_lock = fcntl, dotlock My Dovecot lock option is fcntl only mbox_write_locks = fcntl mbox_read_locks = fcntl now, when user is download a large mail (20 MB) for example, dovecot locks /var/mail/user with fcntl until the users finish downloading the mail ok here comes my question. While the user is downloading the mail , a mail arrives so postfix make some thing weird 1- Postfix creates /var/mail/user.lock for 5 secs , then postfix defer the mail with reason that the /var/mail/user is locked and then delete the /var/mail/user.lock (after 5 secs) My question is ? why postfix create user.lock although it shouldn't because already dovecot fcntl it … 1- Dovecot locks /var/mail/user using FCNTL 2- Posttix at the same time tries to FCNTL /var/mail/user .. but it fail since dovecot already fcnl it. 3- Postfix at the same time add dot lock /var/mail/user for 5 secs then remove the lock. the question is how come postfix dot lock /var/mail although it couldn't FCNTL the file in the first place ??????? what i was expecting is 1- Dovecot locks /var/mail/user using FCNTL 2- Postfix tries to FCNTL /var/mail/user 3- POSTFIX WILL NOT CREATE DOTLOCK file unless the FCNTL is released by dovecot!!!! Please advise if postfix will dot lock the file even if it couldn't FCNTL the file in the first place…… Regards

I downloaded and examined it; it's just a wrapper for /usr/bin/passwd, and there doesn't seem an easy way to modify it to use something other than the system password file. Maybe replace "/usr/bin/passwd" with htpasswd? > and is there another way other than poppassd? Write your own PHP script -- it couldn't be more than a few dozen lines of code for a working skeleton.

[Dovecot] dovecot-lda delivery to Maildir/cur as 'seen'?
by Dale Gallagher 26 Oct '12

26 Oct '12

Hi I've added a server-side feature where authenticated customers sending through our SMTP server have their outbound mail copied to their Sent folder (like Gmail does). The delivery script called by qmail calls dovecot-lda to deliver it to the user's Sent folder. The problem now, is that the Sent folder shows the mail as unread, which MUAs flag (and notify, in the case of some). I've searched the docs and mailing list, but can't find an option to tell dovecot-lda to mark the mail being delivered, as seen/read. If I've missed something, please let me know. If not, then I think it might be a good idea to add a feature to dovecot-lda permitting one to specify delivery to the ./cur subfolder of a Maildir, instead of ./new. Thanks

[Dovecot] Shared folders not shown if "INBOX.shared.%.%" is used with dovecot 2.1.10
by Christoph Bußenius 26 Oct '12

26 Oct '12

Hi, Thunderbird uses the following IMAP command to list shared folders: . list "" INBOX.shared.%.% Dovecot 2.1.10 does not list any folders in response to this command. Dovecot 2.0.21 does list them: * LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed. Both versions list the folders if "*" is used instead of "INBOX.shared.%.%". Because of this issue, shared folders are not shown in Thunderbird. The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird). config: # 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = acl imap_acl acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] Small issue with "submission host"
by Raphael Ordinas 26 Oct '12

26 Oct '12

Hi everyone, I'm facing a small issue with the lda/lmtp "submission_host" feature in dovecot 2.0.14. When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". How can i solve that ? Regards, Raphael

[Dovecot] Public folders and groups
by b m 26 Oct '12

26 Oct '12

Currently I have dovecot working with Active Directory authentication and public folders with acl. In acl I have the users I want to access the public folders. It'll be easier for me to use one group instead of 50 users but I can't get it to work. From where does dovecot get the "group" attribute for a user? Can it read the groups that a user belongs from AD?

[Dovecot] Snarf plugin
by Jeffrey Ross 26 Oct '12

26 Oct '12

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no longer see dovecot crashing when loading the snarf plugin however snarf still does not do anything except make the inbox disappear. I've come to the conclusion that either snarf does not actually work, possible, but I doubt it, or more likely I have a configuration issue preventing it from working. The system is simple, all email is stored in /var/spool/mail/{username} and I want all the mail moved to ~/mbox when the user logs in via imap, similar to uw-imap. Any guidance would really be appreciated.
