[Dovecot] Shared folder
by Stefan Klatt 19 Jan '07

19 Jan '07

Hi, first.. i'm new on this list :-) and use dovecot 1.01rc17 under fedora core 5. And i read the list of the last 4 moth and didn't found answers to my questions........ now i work with shared folders and got it running on the following configuration: namespace private { seperator = . prefix = location = maildir:/srv/imapd/user/%u/maildir inbox = yes } namespace public { seperator = . prefix = Public. location = maildir:/imapd/shared/public/maildir:CONTROL=/imapd/user/%u/shared-settings/public/control:INDEX=/imapd/user/%u/shared-settings/public/index hidden = no } location is one line :-) I have different questions to this configuration: if i use "hidden = no" at the private namespace, the complete namespace isn't viewable, if i use "hidden = yes" i see the prefix "private" at the foldernames in my emailclient. Shouldn't be a non existing hidden option the same like "hidden = no"? if use / as the seperator like dokumented at the wiki it doesn't work. with a dot like the seperator at the directories for the emailfolder it works. is there a way to implement ACL for virtuell user in this configuration? The namespace could be a very interesting idea to give other user access to the own mailbox (e.g. for holiday), but for this each user need it's own acl-file which he can change.... And the special folder like Inbox must be viewable from another user. The both last could be realized with an option like "ACL = /imapd/user/%u/rights" to include an file with acldefinition at the namespacedefiniton. Another way could be a option like "ACL_R = user, user, group, group" inside of the namespacedefinition with definition of user and group outside of the namespacedefintion. For me a LDAP request would the best way :-) i realize the complete emailconfiguration with ldap. Stefan

[Dovecot] How change the order POP checks mail.
by Andreas Andersson 19 Jan '07

19 Jan '07

Hello! I have a problem with the POP when I want to use mbox and Maildirs. The old users are now using uw-imap, but in the future should theres old e-mail be in mbox format and the new e-mails in maildirs. I'am using this code and its worked fine in Squirrelmail and IMAP. namespace private { separator = / inbox = yes hidden = no prefix = "mbox/" location = mbox:~/mail:INBOX=/var/mail/%u } namespace private { separator = / prefix = location = maildir:~/Maildir } but not with POP, I can't find any mail. When I only searching for mbox mail, it worked great. I think thats the problem are the pop who first searching for Maildirs and then mailboxes. So how could I get the Dovecot POP server to first check the mailboxes and then the maildirs? Or how should I go around this problem? Thanks! Andreas Andersson

[Dovecot] Shared folder doesn't work!
by Brian Lavender 19 Jan '07

19 Jan '07

I can't seem to get a shared folder working properly. I am authenticating using pam, and the users have a shell account on the system. Problem is, the permissions on the messages moved into the folder don't maintain properly, and other users can't read the share. I have the following in /etc/dovecot/dovecot.conf namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } # If you create a "namespace public" section, then you need to create # a "namespace private" section namespace private { separator = / prefix = location = maildir:/home/%u/Maildir # There can be only one INBOX, and this setting defines # which namespace has it. inbox = yes } umask = 0007 I am running rc15 from backports on Debian stable. dovecot (1.0.rc15-1~bpo1) sarge-backports; urgency=low * Rebuilt for sarge. * Only changes needed were build dependency on libpq-dev changed back to postgresql-dev, libmysqlclient15-dev changed back to libmysqlclient12-dev, kernel-headers versioned build-dependency removed and debhelper version relaxed to 4. -- Jaldhar H. Vyas <jaldhar(a)debian.org> Mon, 4 Dec 2006 00:48:28 -0500 And here is the share. Two users are accessing it: brian and fred which are both in the colab group.

[Dovecot] rc17: child 15802 (auth) killed with signal 6
by Chris Laif 19 Jan '07

19 Jan '07

I'm using dovecot (rc17) in POP3/IMAP server _and_ proxy mode (pgsql backend). Everything works fine but occasionally I get these messages in the log: dovecot: auth(default): file passdb.c: line 126 (passdb_handle_credentials): assertion failed: (password != NULL) dovecot: auth(default): Raw backtrace: dovecot-auth [0x8062b2b] -> dovecot-auth [0x8062599] -> dovecot-auth [0x805a6ae] -> dovecot-auth [0x805b3b8] -> dovecot-auth [0x8060350] -> dovecot-auth(io_loop_handler_run+0x118) [0x8066458] -> dovecot-auth(io_loop_run+0x28) [0x80658e8] -> dovecot-auth(main+0x78) [0x8057028] -> /lib/libc.so.6(__libc_start_main+0xc6) [0x4007ee36] -> dovecot-auth [0x804f591] dovecot: child 15802 (auth) killed with signal 6 I seems (!) that these messages only appear when someone uses dovecot in in IMAP proxy mode. As I said before, everything works fine -- even reading emails via IMAP-proxy works. Chris

[Dovecot] RC15 problems with dovecot-shared and umask distilled
by Glenn Leavell 18 Jan '07

18 Jan '07

I recently posted about problems I've been having with dovecot-shared and umask in RC15 (using Solaris 9). I've now been able to distill what I'm experiencing into these two separate points: 1. dovecot-uidlist and message files never inherit the dovecot-shared group 2. With umask=0007 these files are created with mode 600 instead of 660: dovecot-uidlist, dovecot.index, dovecot.index.log, messages files (cur,tmp,new and the parent directory *are* created 770) (With regard to #1, I originally posted that individual message files were also not inheriting *permissions* from dovecot-shared, but that turned out to be a case of copying a message with maildir_copy_with_hardlinks = yes.) I can duplicate this consistently; can anyone else? Or has this been fixed in RC16/17? Thanks, Glenn

[Dovecot] dovecot imap logging capabilities
by Michael A. Painter Jr. 18 Jan '07

18 Jan '07

Hello, I have searched but have not found any information on logging imap actions. I want to log when someone uses imap to delete, move, copy, etc. This would greatly help me when someone deletes an email and asks where it went. I get this fairly often from a few users. Any help would be greatly appreciated. Thank you, Michael A. Painter Jr.

[Dovecot] A few rc17 imap crashes
by Chris Wakelin 18 Jan '07

18 Jan '07

We upgraded from 1.0-beta7 to 1.0-rc17 on Tuesday evening and looking at today's logs, just four imap processes out of 90,000+ died. I managed to get core files (the server is running Solaris 8 on Sparc, and Dovecot was compiled with gcc 3.3.2). I hope they're useful! (I should also say that performance between the two versions is roughly similar according to Solaris' process accounting stats, looking at CPU usage and disk blocks accessed.)
