[Dovecot] NULL for password and proxy fields
by bill-dovecot＠carpenter.ORG 04 Feb '08

04 Feb '08

In the course of experimenting with getting dovecot proxying to work, I took a guess at two things. These work fine for me, but now I'm wondering if they are "as designed" or just a lucky accident that might stop working in the future. (I'm using dovecot 1.0.rc17, which is the included version in Ubuntu Feisty. (I am aware that some details change in v1.1, and I'm not worried about that right now.) http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy 1. The wiki page says about password forwarding, "Make sure that the authentication succeeds with any given password. You can do this by using empty passwords." I didn't know exactly now to interpret that last part, so I tried returning NULL as the value of the "password" field for proxy cases. That seems to make dovecot skip the password check will forwarding the user-submitted password to the proxy target host. Is that the intent of that part of that wiki page? 2. It looks like any value at all for the "proxy" field in the passdb lookup turns proxying on. The one exception is a value of NULL for "proxy", in which case proxying is not turned on and proxy-related other fields are ignored. Is that how it's intended to work? If someone can give and informend confirmation that this is as-designed, I can add some clarifying remarks on those points on the wiki page.

[Dovecot] appending domain based on port
by Eric Hester 04 Feb '08

04 Feb '08

I am looking for a way to append a domain to unqualified user names based on the port that the client connected to. Like this: port 9110 - @test.com port 9111 - @other.com port 9112 - @third.com it looks like auth-default-realm does this, but you can only specify it once for the whole process. I know I could do this by running a separate copy of dovecot attached to each port in question, but I would like to do it all in one process if possible. Other questions I have, if I use the auth-default-realm: 1) does it happen before auth lookup I assume? 2) do I have to define the domain i use here as an auth-realm in addition to default?

[Dovecot] Postfix, mailbox_command, Dovecot deliver, LDAP and mail_location
by Patrick Ben Koetter 02 Feb '08

02 Feb '08

I am trying to tell Dovecot deliver to use $mail_location as the location to store mail for system users. From the docs I've read <http://wiki.dovecot.org/MailLocation> I believe this is possible, but mail to my system users always gets delivered to their /home/<USERNAME> homedirectory. Here's what I've done so far: # Postfix main.cf mailbox_command = /usr/lib/dovecot/deliver # Dovecot # dovecot-ldap.conf user_attrs = mailHomeDirectory=home,mailUidNumber=uid,mailGidNumber=gid,mailQuota=quota=maildir:storage,mail=mailHomeDirectory Above you can see, I query for $mail as documented in <http://wiki.dovecot.org/UserDatabase>. # dovecot.conf # dovecot -n # 1.0.5: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/mail.state-of-mind.de.crt ssl_key_file: /etc/ssl/private/mail.state-of-mind.de.key disable_plaintext_auth: no 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_extra_groups: mail mail_location: maildir:~ mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 ntlm passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: virtual group: virtual What am I missing?

[Dovecot] Dovecot, LDAP and something akin to Postfix' "table search order" from virtual deliver.
by Pawel Sawicki 01 Feb '08

01 Feb '08

Hi. /* The short version. */ Is there a way to mimic Postfix' "table search order" in Dovecot's LDAP configuration of pass_filter/user_filter? /* Here goes the detailed description :) */ Just to quote the http://www.postfix.org/virtual.8.html: --- TABLE SEARCH ORDER (...) The search order is as follows. The search stops upon the first successful lookup. (...) o The user(a)domain.tld address, without address exten- sion, is looked up next. o Finally, the recipient @domain is looked up. --- Basicaly this allows to have separate users assigned addresses like j.doe(a)example.com (first account), j.smith(a)example.com (second account) and at the same time to have a "catch all" anything(a)example.com mailbox (for the administrator e.g.). What do I need it for? To have dovecot-lda working. Why? I want Sieve :) The test data may look as follows: account #1: + mail: j.doe(a)example.com + mailAlternateAddress: j.c.doe(a)example.com account #2: + mail: j.smith(a)example.com + mailAlternateAddress: j.t.smith(a)example.com account #3 (administrator): + mail: bofh(a)example.com + mailAlternateAddress: @example.com (means - anything possible) The filter I used is (more or less - for both pass_filter and user_filter): (|(mail=%u)(mailAlternateAddress=%u)(mailAlternateAddress=@%d)) Just for testing purposes I've stripped off some irrelevant data (like checking if the account is active), since that made the filter about 140 characters long ;) The trouble is when there're both a "catch all" and a true account that are linked to different accounts. As an example, if I try to send mail to "j.doe(a)example.com" I receive: dovecot: auth(default): ldap(j.doe(a)example.com): Multiple replies found for user Which is of course true, since the filter returns "account #2" and "account #3". What I'd like to get? I'd like to set the filter to: (|(mail=%u)(mailAlternateAddress=%u)) Where "%u" is expanded to "j.doe(a)example.com" during the first run Then, if dovecot can't find any user that would match this literaly it should retry the search operation, but now with "@example.com" as the "%u". I've tried to fiddle with the filter itself, but I see any reasonable way of doing it. I don't even know if it is possible at all. Could anyone give me a hint? Or maybe it's already on someone's whish list? Some final info. * I've followed the examples on dovecot.org website: http://wiki.dovecot.org/LDA#head-dacb9b9a1f19c3ea86bb6f8caa3d64e3ddad9ef8 * Here's the dovecot's master.conf entry: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/libexec/dovecot/deliver -d ${recipient} Best regards!

[Dovecot] Gnus and dovecot time out
by Richard G Riley 31 Jan '08

31 Jan '08

Could someone suggest what the solution here is? Dovecot is terminating the connection to Gnus after a certain period of activity. It's my own mail server so no need to worry about "hogging resources". Should/could Dovecot be configured to keep the connection alive, or should Gnus be programmed to automatically reopen the conneection? The current problem that one can not leave an IMAP group if the connection is cut by the server. Here is the text posted and replied to on the gnus usenet: ,---- | I have the same problem as the article I link and reproduce below. Is | there a way to get Gnus to keep an IMAP session open without using a | daemon to check for all new messages regularly? | | http://osdir.com/ml/emacs.gnus.user/2006-02/msg00133.html | | ,---- | | Subject: Gnus closing imap connection | | List-id: "Announcements and discussions for GNUS, the GNU Emacs Usenet newsreader $in English$" <info-gnus-english.gnu.org> | | | | My IMAP connection closes and Gnus does not reopen it.
