[Dovecot] Shared mailboxes basics
by Thomas Hummel 22 Mar '10

22 Mar '10

Hello Timo, I'm trying to set up shared mailboxes with dovecot-1.2.11/Maildir. I previsouly used public namespaces with 1.1+ to somehow implement them but I'm looking at the real ones now. I've read the Wiki but I'm still confused or not 100% sure about the following (basic) points : 1. Namespaces prefixes My understanding is that a namespace prefix is just an escape mechanism for the client to access the mailboxes this namespace holds. So the real location is _only_ defined by the "location" directive, independently of what the prefix is. So, for example, If you've got : prefix="foo/bar/" location=maildir:/some/folder/%u mailboxes are physically in /some/folder/%u, not in /foo/bar/some/folder/%u or something am I correct ? 2. Other Users mailboxes RFC234 states that shared mailboxes (which they call "Other Users" mailboxes) are "mailboxes from the Personal Namespaces of other users." Dovecot's Wiki takes as an example : # User's private mail location. mail_location = maildir:~/Maildir # You need to create also a private namespace: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } and states : "This creates a shared/ namespace under which each user's mailboxes are." My understanding is that # User's private mail location. mail_location = maildir:~/Maildir and location = maildir:%%h/Maildir implies that mailboxes in both the private and the shared/ namespace are physically in the same location (under the "$HOME/Maildir" directory of the user who shares his mailbox) . Am I correct ? I tried the following set up : namespace private { separator = / location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot-test/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace shared { separator = / prefix = "#shared/%%u/" location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-test/indexes/%1u/%u/shared/%%u subscriptions = no list = yes # will try children later } the user doveimap has the following mailboxes : # pwd /courriel/boites # ls -l doveimap total 64 drwx------ 5 doveimap Invites 4096 Oct 23 13:38 .Trash drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo.rescence drwx------ 5 doveimap Invites 4096 Oct 23 13:43 .testcopy drwx------ 2 doveimap Invites 4096 Mar 15 17:08 cur drwx------ 2 doveimap Invites 4096 Mar 15 17:07 new drwx------ 2 doveimap Invites 4096 Mar 15 17:07 tmp I can perform for instance : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot test ready. x login doveimap xxxxxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 setacl INBOX dovepop rl 1 OK Setacl complete. But isn't a client like Thunderbird (3.0.3) supposed to . show me the #shared (even if no one shares mailboxes to me) "folder" (because of list = yes )? . let me share, let's say the .sous.arbo mailbox ? If yes, how ? Or should I first pre-set some acl files ??? For now, it says : "This is a personnal mail folder. It is not shared."

[Dovecot] dovecot-2.0.beta3 tcpwrapper support in Solaris
by Tomi Vainio 22 Mar '10

22 Mar '10

Hi, 2.0 compiles fine in Solaris but and I've found only one glitch so far. Tcpwapper support needs some tweaks. I need to add CPPFLAGS=/usr/sfw/include because tcpd.h is in there. Then also LDFLAGS='-R/usr/sfw/lib -L/usr/sfw/lib' is needed. It would be nice to have --with-tcpwrap-dir or something. After this linking gives an error Undefined first referenced symbol in file deny_severity /usr/sfw/lib//libwrap.so allow_severity /usr/sfw/lib//libwrap.so These are not defined but application itself should define these globally so I've added these to configure and src/util/tcpwrap.c #include <syslog.h> int allow_severity = LOG_INFO; int deny_severity = LOG_WARNING; Tomppa

[Dovecot] Dovecot 1.2.11 renames Maildir filenames on first read of foreign POPstore - how to avoid
by Sam C. Nicholson !! 22 Mar '10

22 Mar '10

Greetings, I'm converting from a custom POPstore ( > 100,000 messages) which is Maildir-like and uses the filename as the UIDL and doesn't store it inside the message. I'm wondering whether there is hope for config-file options to keep devecot from renaming files when it first sees them, or whether I'm going to need to create a new backend for dovecot based on Maildir. The renaming not only blows my current UIDLs, it seems to upset Dovecot's indexing, Cheers! -sam My POPstore looks like this: /zdata/domain/%d/folders/%n/{cur, new, tmp}/ and message filenames like this: msg.yyyy:mm:dd:hh:mm:ss.random I was able to get Dovecot to see the store by the symlink: INBOX -> . Here are the log messages regarding the index warnings: Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:02:20:16:37:56.951.2376 -> 1269258346.M323507P15988.mailbase Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:01:08:00:00:50.25142.18396 -> 1269258346.M323508P15988.mailbase ^ |____Dovecot message name appears to increment here #dovecot -c config -n # 1.2.11: /home/scion/Packages/dovecot-1211/dovecot.conf.short Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] configure dovecot to read-only ?
by Frank Gadegast 22 Mar '10

22 Mar '10

Hi, I like to configure the use of IMAP to read-only on a special backup system. Users should only be able to read archived email, they should not be able to create folders or delete email. I know how to configure user- or folder-specific acls, but it seems to be a bit complicated to setup a ACL for every user. Any simple global option available ?

[Dovecot] Possible programming error in maildir_mail_get_save_date
by Rainer Weikusat 22 Mar '10

22 Mar '10

The maildir_mail_gate_save_date routine (lib-storage/index/maildir/maildir-mail.c) returns the save date when that was determined by looking at the ctime of the corresponding file. This is different from all other get_save_date routines which either return -1 if the date could not be determined or 0 to signal success. A particular problem caused by this would be that the first_nonexpunged_timestamp routine (plugins/expire/expire-plugin) never finds a not-yet-expired e-mail after the first message in a mailbox has been expunged when using the maildir storage and file ctimes for save dates, causing the expire_mailbox_transaction_commit function (same file) to delete expiry information for the mailbox in question from the expires table despite mails supposed to expire still exist.

[Dovecot] Public Folder for mailinglist with deliver
by Sebastian Heil 21 Mar '10

21 Mar '10

Hello Everybody, I'm looking for a nice way to implement the following: We are running a mail server for system users who are having their own mailbox. Now there's the idea to subscribe for a few mailinglists which are then available for the user per shared/public folder. So they can simply subscribe and unsubscribe with their MUA. For every mailinglist subscription there should exist an own email account with own mail directory. The namespaces are already working (in a test environment). But I haven't found any implementation to realize this nicely with deliver. The possiblities I'm thinking about are: -create a somewhere in userdb a passwd entry for each mailinglist email address with the corresponding directory -create a static userdb entry, but then deliver cannot check if an email address/mailbox exists. I think both ideas aren't a good implementation. So I'm asking you for help. Has someone a similar setup or a little idea how to make this work with deliver. Thanks in advance Sebastian

[Dovecot] Sendmail + deliver; silent errors.
by Daryl Tester 20 Mar '10

20 Mar '10

Hi all. I've got a bit of a peculiar issue here. I'm running dovecot 1.2.9 on an Ubuntu 9.10 box using Sendmail 8.14.3. I've set up Sendmail similar to <http://wiki.dovecot.org/LDA/Sendmail> except that *) dovecot's deliver is configured as my default local mailer, so some of the flags for the Mailer definition had to be adjusted accordingly. *) The setuid users listed in the wiki kept result in setgid() failures from deliver, so I've changed it to root:mail (mail being sendmail's MDA group), with permissions as u+s,g+rx,o-rwx When sendmail attempts delivery, I'm getting "deferred: deliver failed with EX_TEMP", but nothing recorded in the log files. I've embarrassingly widened the permissions of /var/log/dovecot and the files contained within to read/write everyone, just to ensure that whomever it's running as has access, but the log files aren't updated. The peculiar thing kicks in when I attempt to debug this. So far I have (amongst other things): *) Run deliver from the command line logged in as "mail". *) written a shell wrapper script to be able to confirm things like the user ID that was invoking deliver. *) both in the shell script, and as an mailer definition in sendmail, strace'd (using a setuid root binary) deliver to capture what it was doing. Whenever I do any of the above, deliver works perfectly, and appears to log correctly. It only appears to bork when no-one is watching it, which is quite frustrating when trying to fix it. Help? Configuration of dovecot follows: # 1.2.9: /etc/opt/dovecot-1.2.9/dovecot.conf # OS: Linux 2.6.31-14-server x86_64 Ubuntu 9.10 ext3 base_dir: /var/run/dovecot-1.2.9/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log protocols: pop3 imap imaps ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot-1.2.9//login login_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3-login mail_uid: vmail mail_gid: vmail mail_location: maildir:/vmail/spool/%u:LAYOUT=fs mail_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot-1.2.9/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)handcraftedcomputers.com.au auth_socket_path: /var/run/dovecot-1.2.9/auth-master auth default: verbose: yes passdb: driver: passwd-file args: /vmail/auth/passwd userdb: driver: static args: uid=vmail gid=vmail socket: type: listen master: path: /var/run/dovecot-1.2.9/auth-master mode: 384 user: vmail group: vmail -- Regards, Daryl Tester Member of the Amalgamated Australian Association Against Apostrophe Abuse.
