[Dovecot] How to disable system users from receiving mail?
by Paul H Park 17 Aug '09

17 Aug '09

I know that login can be disable for system users and groups, but how do I refuse email for system groups? It's a bit of a security/maintenance irritation - I don't want to check for such spam mail, since that is possible. Thanks for any help!! Answer preferably given, so that I can configure it through webmin please.

[Dovecot] can't deliver with Kerberos username
by Nikolay Shopik 16 Aug '09

16 Aug '09

I've been trying to use Kerberos and PLAIN text file for authentication. I've setup deliver in postfix master.cf and make sure correct username are expanded but deliver is always told me "user unknown". I can logon into mailbox using Kerberos w/o problems and can send emails. Looks like Dovecot lookup up passwd files and not finding users which are in Kerberos realm. # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imap ssl_cert_file: /etc/postfix/new_chained.crt ssl_key_file: /etc/postfix/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes mail_location: maildir:/var/mail/store/%u dotlock_use_excl: yes maildir_copy_with_hardlinks: yes auth default: mechanisms: PLAIN CRAM-MD5 GSSAPI passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/store/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: root group: root plugin: sieve: /var/mail/store/%u/sieve

[Dovecot] Listing shared mailboxes with a domainpart
by Mathias Tausig 16 Aug '09

16 Aug '09

Hy! I am currently configuring a new mailserver using postfix and dovecot 1.2.1. The filesystem strucutre in my spool directory is user1/ user2/ domain/info/ domain/office/ user1 and unser2 are ordinary users mailboxes, the latter two contain the virtual mailboxes for info@domain and office@domain as created by postfix. I want these virtual mailboxes (all of them are in maildir format) to be shared to certain real users. I configured a shared namespace: namespace shared { separator = / prefix = shared/%%d/%%n/ location = maildir:/var/spool/vmaildir/%%d/%%n/ #I tried ths as well # prefix = shared/%%u/ # location = maildir:/var/spool/vmaildir/%%u/ hidden = no subscriptions = no list = yes inbox = no } Then I configured a dictionary to list the folders, as described in the wiki: plugin { acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } where /etc/dovecot/dovecot-dict-sql.conf holds map { pattern = shared/shared-boxes/user/$to/$from table = virtual_user_shares value_field = dummy fields { from_user = $from to_user = $to } } The database table consists of +-------------+------------+-------+ | from_user | to_user | dummy | +-------------+------------+-------+ | info@domain | user1 | 1 | +-------------+------------+-------+ But when I login as user1 I can neither see nor subscribe to the info@domain mailbox. In the "flat" case (sharing the user2 mailbox to user1), this setup works. I am pretty clueless how to go on. cheers Mathias

[Dovecot] Released Sieve v0.1.10 for Dovecot v1.2.2
by Stephan Bosch 15 Aug '09

15 Aug '09

Hello Dovecot users, In the last week two nasty bugs were found in the new Sieve implementation. Primarily, the include extension did not work when a compiled binary was loaded from disk. This is something that is still not tested by the test suite, giving this bug the opportunity to slip through. Also, the value matching implementation would sometimes cause a assertion failure. Other than that, various small bugs were fixed. On the more positive side, I have implemented support for the new mailbox extension (RFC 5490), which provides the means to test whether a mailbox exists. Also, it adds the :create argument to the fileinto command, which makes sure that the target folder is created before saving is attempted. Of course, this is only useful when deliver is used with the -n option. There wasn't a great need for this extension, but I could use it in the test suite and it was almost trivial to implement. In other news, I have further developed the sieve-filter command line tool. It is getting closer to a usable state, being able to filter a large number of messages in an existing mailbox, but its use is currently still very much discouraged as it tends to be very good at eating mailboxes when the user is less attentive. It needs more command line configuration options, a simulation mode to perform a dry run, and a man page that describes its use and its dangers. Changelog for Sieve v0.1.10: * Changed action execution of fileinto and keep. These changes depend on API additions in Dovecot, making this release depend on Dovecot v1.2.2 or newer. * Further developed the sieve-filter command line tool. This required a few changes to the action execution of the Sieve engine. The tool was successfully tested on folders with a few 100k spam messages. However, the commandline options are still incomplete, a man page is missing and it needs much more testing before I can recommend anyone to use this tool. + Added support for the mailbox extension. This allows checking whether a mailbox exists using the mailboxexists command and it adds the :create argument to the fileinto command to create the mailbox when it is missing. The :create feature is useless unless the Deliver LDA is run with the -n option. + Improved the testsuite with tests for message delivery. Messages stored using keep and fileinto can be fed back into the Sieve engine for verification. This includes testing of applied IMAP flags. + Updated the man pages with the new method of specifying the supported extensions using + and - (for the -x parameter of the sieve tools) + Further developed the deprecated notify extension. A dummy for the denotify command exists, meaning that its use does not cause an error anymore. - Fixed a bug in the derivation of the binary path from the script path. A bare filename would yield a path relative to root. - Fixed a bug in the value matching code. The context data now uses a proper pool in stead of the data stack. Bug reported by Jan Sechser. - Fixed assertion fail in the include extension caused by missing initialization upon binary load. This bug surfaces only for stored binaries. Bug reported by Tom Hendrikx. - Fixed include error message for failed :global include. It mentioned the wrong config parameter. - Fixed broken wiki reference in an error message of the plugin about the 'sieve' setting. - Fixed behavior of fileinto when delivering into a namespace prefix. Previous fix used the wrong storage. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz.sig Have fun testing the new releases and don't hesitate to notify me when there are problems. Please include your configuration, the involved Sieve scripts and an example message in any bug or problem report when possible, so that I can easily reproduce the issue. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Re: [Dovecot] Redirecting mail gives 'mail forwarding loop' to the sender - calling for sieve help
by Andrés Yacopino 15 Aug '09

15 Aug '09

Yes, the configuration seems odd or interesting as you said. The idea behind this is: - Before scripts will be use for filtering spam, when they have SPAM header. Not problem at it. - User scripts will be used for vacation messages. These are created with Squirrelmail and avelsize plugin (user interaction) - After scripts will be used for doing redirections, such as forwarding mail to a blackberry account(not problem at it) or forwarding to another user account (in the same domain, the problem is here). The reason not to put the redirections or forwarding in users scripts is to avoid users deleting redirections and have in one file all the redirections. I also try to use redirections from avelsieve plugin (0.9.9.9) and it works the forwarding but it didn't work the keep command, the mail is forwarded but the user doesn't have a copy of it. I will investigate your advice for envelope or try to use user's scripts. I didn't know about original headers, if this in RFC sieve documents? Thanks Timo and thanks Stephan for the tips. Greetings, Andrés. Andrés Yacopino. Dpto Sistemas AcaSalud

[Dovecot] Very long establishment time for secondary connections
by Jeff Mitchell 14 Aug '09

14 Aug '09

Hello, I'm currently on Dovecot 1.1.17 and I have a user that runs into a problem quite a lot. She's using Thunderbird on a Mac. When she sends mail, Thunderbird is set up to save sent mail to her Sent folder. Often (usually when she has not sent another mail for a long while) when she sends mail, Thunderbird sits there saying "Copying message to Sent folder" for about thirty seconds. My best guess, after looking at dovecot messages in syslog related to her login, is that Thunderbird is using a secondary imap process to do this copying and this connection times out due to inactivity, so that when she sends mail it has to reestablish itself. For some reason this reestablishment seems to take a very long time, even though her initial login/connection when she opens Thunderbird is very fast. I looked for a way to increase the inactivity time in dovecot.conf but didn't see one. I don't know of any other user that has this problem, which makes me suspicious of her client rather than Dovecot. Pretty much everyone is using Thunderbird, although she's the only one using it on a Mac. Is it possible/likely that it takes so long because for some reason Thunderbird on a Mac doesn't notice that the second connection has died and is taking a long time trying to use the first invalid connection before reestablishment? Or is it likely that this is a Dovecot problem and I simply haven't figured out what's going on, yet? All help very much appreciated. Thanks, Jeff

[Dovecot] Upgrade question from 1.1 to 1.2
by Wouter van der Schagt 14 Aug '09

14 Aug '09

Good afternoon, I am considering to upgrade from Dovecot 1.1.18 to 1.2.x and was reading your Wiki regarding any changes and found: "If you were using e.g. mail_location = maildir:/var/mail/%h, just change it to mail_location = maildir:%h and add /var/mail/ prefix to home dirs." I am currently using: "mail_location = maildir:~/Maildir" in combination with vpopmail. Does this need to be changed? or is ~/Maildir considered an absolute directory? Is there anything else I should be aware of ? Sincerely, - Wouter van der Schagt

[Dovecot] Dovecot Proxy
by Michel Bulgado 14 Aug '09

14 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS? Thanks Michel

[Dovecot] QUOTA not appearing in CAPA
by Tim Traver 14 Aug '09

14 Aug '09

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules from directory: /usr/local/lib/dovecot/imap IModule loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home=/tmp IQuota root: name= backend=maildir args= IEffective uid=65534, gid=65534, home=/tmp and then I see the following in the dovecot logs : Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so when I log into the IMAP port, I get the following greeting : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. So it seems there is no QUOTA support for the IMAP server to query for the quota file... can someone help me as to a direction to go here??? The reason I need it is because I believe the web client relies on the QUOTA being in the CAPA in order to show it... Thanks, Tim.

[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve

[Dovecot] Dovecot proxy server
by michel＠casa.co.cu 13 Aug '09

13 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS?

[Dovecot] user_global_* ldap deliver
by Noel Leistad 12 Aug '09

12 Aug '09

Searched archive, but failed to find... :-( "deliver" does not honor user_global_* from dovecot-ldap.conf or userdb static{} also it looks like delivery attempts being made to %n/Maildir/cur ?? one other curious thing, use of ${recipient} in master.cf|deliver command causes the "passdb ldap" lookups to be completely ignored? only checks passdb and ignores userdb compleletely? IF I put noel(at)metc(dot)net into passwd.dovecot using passdb flatfile, auth and delivery seem to work. Thanks for any direction. I lament I couldn't get farther on my own.

[Dovecot] Dovecot Versions and Debian
by Mario Antonio 12 Aug '09

12 Aug '09

If you want to run Dovecot on Debian Lenny for a Production System (with Fast Upgrade System for Security Patches), What would you recommend? Stick to the current port with Dovecot Version 1.0.15 (1:1.0.15-2.3) Use Backports Version 1.1.13 (1:1.1.13-2~bpo50+1) or Use any of the packages from: ---------------------------------------------------------------------------------------------------------------------- Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main ---------------------------------------------------------------------------------------------------------------------- Do you find any compelling reason for not using version 1.0.15 ? (Besides of ACL limitations ...) Regards, Mario Antonio
