[Dovecot] Problem migration from Courier-Imap to Dovecot
by Jose Luis Marin Perez 23 Jun '09

23 Jun '09

Dear friends, My intention is to migrate from Courier-Imap Dovecot 4.4.1 to 1.1.16, the problem is that I've noticed that when creating folders using the Courier does not create the file courierimapsubscribed therefore I doubt if this will bring me problems trying to perform the migration script by courier-dovecot-migrate.pl drwx------ 8 vpopmail vchkpw 4096 Jun 18 16:38 . drwx------ 3 vpopmail vchkpw 4096 Jun 18 09:32 .. drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:36 courierimapkeywords -rw-r--r-- 1 vpopmail vchkpw 265566 Jun 18 16:36 courierimapuiddb drwx------ 2 vpopmail vchkpw 593920 Jun 16 10:05 cur drwx------ 2 vpopmail vchkpw 4096 Jun 18 09:32 new drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .Personal drwx------ 6 vpopmail vchkpw 4096 Jun 18 16:38 .RPV drwx------ 2 vpopmail vchkpw 4096 Jun 18 16:41 tmp Please could help me with this problem because I do not have much experience in this type of migration. Thanks Jose Luis _________________________________________________________________ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE

[Dovecot] CRAM-MD5 authentication but plain-md5 password storage.
by Richard 22 Jun '09

22 Jun '09

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf } <snipped> } In my dovecot-sql.conf I've setup the password scheme to be: default_pass_scheme = MD5 Somehow this does not work, the error I see in the logfile is: auth-worker(default): password(info(a)richard5.tld,127.0.0.1): Requested CRAM-MD5 scheme, but we have only MD5 Is there a way to get this working or does this feature only works with passwords stored in plain text ? Thanks! Richard

[Dovecot] dedup in dovecot?
by Roy Sigurd Karlsbakk 22 Jun '09

22 Jun '09

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't necessarily be a duplicate in terms of headers (BCCs and so on). Would it be possible to dedup the content in terms of using separate files for the header and content and then deduping this with hard or symbolic links? Sorry if this is an old question, but I couldn't find anything about it. roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy(a)karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

[Dovecot] Dovecot v1.2 share user Maildir problems with %%h
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm using Dovecot v1.2 9133:f65112bd90b3 with attached config and try to share user Maildirs. The ACLs are working. However the %%h gives me head aches, well, the location in general: I've copied the default mail_location and changed its CONTROL and INDEX settings: namespace shared { ... location = maildir:%%h/Maildir:CONTROL=/var/cache/dovecot/%i/control/shared/%%u:INDEX=/var/cache/dovecot/%i/index/shared/%%u } Now the first wows are that: a) IMAP insists to connect to $install_prefix/var/run/dovecot/auth-master instead of /var/run/dovecot/auth-master used by deliver. My workaround was to symlink /var/run/dovecot/ to $install_prefix/var/run/dovecot/ b) This socket needs to be r/w for every user, which is a security risk as mentioned in the conf and the default permission is 0600. For deliver I changed the socket attr to permission 0660 and group=mail; for making %%h work I added mail_access_groups=mail c) The user's mailbox is not found still, because: 2009-06-17 15:04:57 auth(default): Info: master in: USER 1 testusr/INBOX service=internal 2009-06-17 15:04:57 auth(default): Info: auth(?): Invalid username: testusr/INBOX 2009-06-17 15:04:57 auth(default): Info: userdb(?): Username contains disallowed character: 0x2f 2009-06-17 15:04:57 auth(default): Info: master out: NOTFOUND 1 The imap process passes the mailbox to the authentificator, too. Also, it changes the '.' to '/', although rawlog has: select "shared.testusr.INBOX" If I allow "/" as userchar, I get: 2009-06-17 15:43:00 auth(default): Info: ldap(testusr/INBOX): Unknown user 2009-06-17 15:43:00 auth(default): Info: master out: NOTFOUND 1 It reallt requests the data of user "testusr/INBOX". d) If I use location = maildir:/home/%%u/Maildir: instead of %%h/Maildir, things work _except_ that some user's %%h != /home/%%u . ============== Basically I have yet another problem with location in the user-share namespace: Because one can override the default mail_location for each user, I did so for some users. Some of them even do not have the Maildir. That leads to the problem, that I need one shared namespace for each location template. There had been a suggestion of a special user-shared namespace a while back. How about to add the base location in the shared-mailboxes.db? So instead of "1" the value is the base of the shared location, e.g. maildir:/local/testuser or maildir:/home/user/Maildir..., and some %%? token takes the string from there. Because the path is known from the db now, the other problems mentioned above do no longer apply.

That is the problem, fetchmail just forwards it to port 25 (I think) and I need to work out what to put between fetchmail and dovecot in order to get the mail into the correct folders... And I am just going around in circles on this at the moment. Any hint would be appreciated! Thanks, Michael

[Dovecot] auth_cache multiple passwords ?
by Geoffroy Desvernay 22 Jun '09

22 Jun '09

Hi, First, thanks Timo and Stefan for this great IMAP/Sieve implementation... We are using 1.1.16+cmu_sieve/managesieve additions for now (following releases since ~ 1.0.1). We have a specific problem here with auth-cache: We use direct imap/sieve connection from different clients, using LDAP password: everything is fine. The problem appears with our webmail access using a web-SSO system (jasig's CAS), using one-time-tickets as password for imap connections (checked by pam_cas module for now). For a single webmail connection par login, it work, thanks to cache_key using client's IP. But for multiple use of the same login in the webmail, there are more than one 'password' valid at a time… What may be the 'correct' solution: - patching auth-cache.c (auth_cache_lookup function ?) - writing a different login backend ? - ??? Hope I'm clear enough… -- geoffroy desvernay Ecole Centrale de Marseille

[Dovecot] dovecot-acl file questions
by Steffen Kaiser 22 Jun '09

22 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, playing around with Dovecot's v1.2 ACLs I wondered about some things about the dovecot-acl files: + They are created within the Maildirs, as described in http://wiki.dovecot.org/ACL. But why? Shouldn't they belong to the CONTROL= directories? So it is more compatible with filesystem quota. + They have 0666 permissions, but all other files (e.g. when I create a new mailbox) have 0660 permissions. Are the permissions selected explicitly to allow "a"-right for other (system) users? + When one removes all rights, the size of the file drops to zero. The wasted space is no great deal; but how much processing is wasted if such file is present? I mean, the log says that the files are opened very regularily. Would it help to remove zero-size files?
