[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

[Dovecot] Active Directory 2003 user database and passwords with special characters
by Boris PINON 29 Oct '12

29 Oct '12

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| auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.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.

[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.

[Dovecot] Creating Maildir and populating with emails via external Python process
by Bradley Rintoul 26 Oct '12

26 Oct '12

Hello: I'm using Dovecot to provide IMAP services for Thunderbird clients. The user's mail is stored in Maildir format and the individual emails which the user "receives" are actually downloaded and put into the Maildir "repository" using a Python email client (POP3 client). I am trying to create the dovecot-uidlist file and maintain the "next UID" value within it, but I am having trouble with the UIDVALIDITY and the 128 bit mailbox global UID among other things. How can I "seed" a dovecot-uidlist file with these values..? Sorry if the information is not much to go on, please let me know what more information you might need to help point me in the right direction. Thanks, B. RIntoul

[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver
by Troy Vitullo 25 Oct '12

25 Oct '12

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks
by Benedetto Vassallo 23 Oct '12

23 Oct '12

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

[Dovecot] 76Gb to 146Gb [Resolved]
by Spyros Tsiolis 23 Oct '12

23 Oct '12

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here. Alex, you are a true sport. Thank you again people. All the Best, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis
