[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. Thanks, Jeff dovecot -n # 2.1.10: //etc/dovecot/dovecot.conf # OS: Linux 3.6.2-1.fc16.x86_64 x86_64 Fedora release 16 (Verne) mail_debug = yes mail_location = mbox:~/mail:INBOX=~/mbox mail_plugins = snarf 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:INDEX=MEMORY prefix = /snarf separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mbox_snarf = ~/mbox 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 = snarf zlib imap_zlib } syslog: Oct 24 13:33:27 xyzzy dovecot: master: Warning: SIGHUP received - reloading configuration Oct 24 13:33:27 xyzzy dovecot: imap: Server shutting down. in=277 out=106519 Oct 24 13:33:27 xyzzy dovecot: imap: Server shutting down. in=422 out=2893 Oct 24 13:33:29 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=::1, lip=::1, mpid=28089, secured, session=<L6okfNHM2AAAAAAAAAAAAAAAAAAAAAAB> Oct 24 13:33:29 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 24 13:33:29 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 24 13:33:29 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 24 13:33:29 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 24 13:33:29 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 24 13:33:29 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 24 13:33:29 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 24 13:33:29 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:INDEX=MEMORY Oct 24 13:33:29 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt= Oct 24 13:33:29 xyzzy dovecot: imap(jeff): Disconnected: Logged out in=117 out=1504

[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 24 Oct '12

24 Oct '12

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail. Postfix used the following flags in calling spamc and dovecot: flags=DRhu user=dovecot:secmail argv=/usr/bin/spamc -u ${recipient} -e /usr/lib/dovecot/deliver -d ${recipient} after an upgrade from Debian lenny to squeeze we were able to get everything working except spam filtering. Spamassassin is able to judge whether the mail coming in is spam but everything stops there.

[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
