[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 19 Jan '07

19 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.)

[Dovecot] default_mail_env/mail_location syntax changes
by Mike Brown 18 Jan '07

18 Jan '07

Sorry, I tried to find this info on the wiki and in the docs, but couldn't quite figure it out. Dovecot 1.0rc8 introduced this change: "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" If I need a custom INBOX location but the default behavior of using the first of [/ or ~/mail or ~/Mail] having a .imap subdirectory, how do I go about specifying that? That is, on my system, - inbox file: ~/Mailbox - mail storage dir: ~/mail OR ~/Mail (it varies by user) - all files are in mbox format Thanks, Mike

[Dovecot] some Maildir files not honoring dovecot-shared
by Glenn Leavell 18 Jan '07

18 Jan '07

I'm using RC15 on Solaris 9. The wiki indicates that when a dovecot-shared file exists, "Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc." In my case, Dovecot *is* creating new index files based on dovecot-shared, but dovecot-uidlist and individual message files don't completely match the permissions/group template. Specifically, dovecot-uidlist isn't taking the group from dovecot-uidlist, and individual messages files don't seem to be honoring dovecot-shared at all (group or permissions). Here's an example; every file and directory below in .abusetest-in was created by Dovecot *except* for dovecot-shared (I let Dovecot create cur, new, tmp just to see what it would do, but I know that I can create and fix the group and permissions on these directories myself in a sharing situation): glenn@tony:~/Maildir/.abusetest-in$ ls -lR .: total 34 drwx------ 2 glenn adm 512 Jan 9 09:58 cur/ -rwxrwx--- 1 glenn abuse 0 Jan 9 09:57 dovecot-shared* -rw-rw---- 1 glenn adm 44 Jan 9 09:58 dovecot-uidlist -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index -rw-rw---- 1 glenn abuse 10272 Jan 9 09:58 dovecot.index.cache -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index.log drwx------ 2 glenn adm 512 Jan 9 09:58 new/ drwx------ 2 glenn adm 512 Jan 9 09:58 tmp/ ./cur: total 4 -rw------- 2 glenn adm 1438 Jan 5 09:59 1168354728.P15661Q0M891161.tony:2,S ./new: total 0 ./tmp: total 0 glenn@tony:~/Maildir/.abusetest-in$ I see in the RC16 release notes that there was a fix for the dovecot-keywords file, but it doesn't mention these other files. Is this a bug, or am I misunderstanding how the dovecot-shared file should work?

[Dovecot] assertion failed
by Shaun T. Erickson 18 Jan '07

18 Jan '07

I installed dovecot on a RH9 server this evening, via an RPM from atrpms.net (dovecot-1.0-0_34.rc15.RHL9.at.i386.rpm). The auth portion is working perfectly, as I'm using it to do SMTP AUTH with my postfix 2.3.5 installation. I have configured it to provide imaps. When I connect to it, it rapidly connects, disconnects, connects ... ad infinitum, reporting this, in the logs, each time: Dec 30 16:03:33 max dovecot: imap-login: Login: user=<ste>, method=plain, rip=192.168.32.168, lip=65.206.7.147, TLS Dec 30 16:03:33 max dovecot: IMAP(ste): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) Dec 30 16:03:33 max dovecot:child 19228 (imap) killed with signal 6 Here is my dovecot.conf file: listen = [*] protocols = imaps disable_plaintext_auth = yes ssl_cert_file = /etc/postfix/max.blackdogsoft.net.crt ssl_key_file = /etc/postfix/max.blackdogsoft.net.key ssl_ca_file = /etc/postfix/cacert.pem default_mail_env = mbox:%h:INBOX=/var/mail/%u mail_read_mmaped = yes verbose_proctitle = yes protocol lda { postmaster_address = postmaster(a)blackdogsoft.net } auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/provate/auth mode = 0660 user = postfix group = postfix } } } Suggestions? -- -ste

[Dovecot] Correct usage of NFS mounted Maildirs
by Fran Fabrizio 18 Jan '07

18 Jan '07

Dovecot 1.0RC15 running on Fedora Core 5 kernel 2.6.18-1.2257.fc5smp. A SLES10 server (kernel 2.6.16.21-0.8-smp) has the home directories on an ext3 partition mounted with options (rw,acl,user_xattr,usrquota) which is then exposed as an NFS mount with server side options (rw,no_root_squash,no_acl,async). The home directories include Maildirs to which postfix delivers. The Fedora Core 5 dovecot&postfix machine then mounts this NFS mount with options (rw,hard,intr) Dovecot variables: mmap_disable=yes lock_method=dotlock default_mail_env = maildir:~/Maildir:INDEX=/usr/local/dovecot/indexes/%u (only one dovecot server and wanted to see if local indices helped) I didn't turn off the attribute caching of NFS since I only have one dovecot server, I think the wiki said it was safe to leave on in this case. With this configuration, I am seeing a lot of NFS Stale Filehandle errors, even after moving the index files to a local disk. Here's an excerpt from the log: dovecot: Dec 22 11:23:06 Info: Dovecot v1.0.rc15 starting up dovecot: Dec 22 11:23:22 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:23:24 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:24:48 Info: imap-login: Login: user=<nfsuser1>, method=plain, rip=138.26.64.50, lip=138.26.64.5 dovecot: Dec 22 11:26:43 Error: IMAP(nfsuser1): inotify_add_watch(/nethome/facstaff/nfsuser1/Maildir/.Trash/new) failed: Stale NFS file handle dovecot: Dec 22 11:26:43 Error: IMAP(nfsuser1): inotify_add_watch(/nethome/facstaff/nfsuser1/Maildir/new) failed: Stale NFS file handle To be honest, I'm not 100% sure this is a dovecot problem, because I also see that I am getting stale filehandles when postfix tries to deliver the mail to the Maildir, but I'm curious as to whether this is because of something dovecot did because I have it misconfigured. Does anything about my dovecot config provide any clues as to what I might have done wrong? The NFS mounts are completely stable everywhere except within the Maildirs. From the shell, I can run a loop to call 'ls' 1000 times outside of a Maildir and it works fine. Inside a Maildir, I will get Stale NFS Filehandle errors before long. Does this sound like it could have something to do with my Dovecot config, given that it is happening even after I moved indices to the local disk (still getting stale filehandle errors on files like dovecot-keywords). I performed the following procedure: - shut down dovecot - did a rm-rf Maildir on my test account - unmounted the NFS mount /nethome/facstaff - remounted the NFS mount /nethome/facstaff - set the index files to be local in dovecot.conf and created that directory (/usr/local/dovecot/index/) - sent a few test mails to the user (to recreate the Maildir) - started dovecot - logged in (via Thunderbird) to account through dovecot. - read test message - deleted test message - opened shell to dovecot server - cd'ed into user's Maildir - ran 'ls' a few times. Got Stale Filehandle errors after a few. - back in Thunderbird, tried to read/move/delete other test mails, got the above errors in the log. If it's not a dovecot issue I know it's off-topic, but has anyone else seen similar? I might be imagining this, but I think the problem started when I moved from SLES9 to SLES10 for my fileserver (newer kernel, newer version of NFS, perhaps an incompatibility here?) Thanks, Fran

[Dovecot] Custom mail directory with LDAP
by Maykel Moya 18 Jan '07

18 Jan '07

For certain users, I have their mail boxes under /srv/mpop/<username>/Maildir. For the rest, I have their mail boxes under /srv/vmail/<username>/Maildir. mpop/ users are stored in LDAP, vmail/ users are local users so I discard the idea of set a fixed mail_location. In dovecot-ldap.conf I can't get the picture to set /srv/mpop/<username>/Maildir as mail. I'd tried user_attrs = /srv/mpop/uid/Maildir=mail but watching the logs I saw that a '/srv/mpop/uid/Maildir' is queried to the LDAP Server. Would be nice to have a user_global_mail equivalent to user_global_uid for LDAP user lookups. Regards, maykel

[Dovecot] auth unix sockets
by Uldis Pakuls 18 Jan '07

18 Jan '07

Hi, I'm working on "avelsieve" SqurrelMail plug-in to implement SIEVE "file" back end for dovecot. 1. My be someone my explain me, how to use client auth socket to authenticate against dovecot-auth unix socket. As fas as I understood login must be sent in form "user\0\user\0password" as base64 encoded string. pp code (I'm using socket used by postfix auth): -------------------- <?php $authstr = base64_encode('test@virtual.net\0test@virtual.net\0test'); $fp = fsockopen("unix:///var/spool/postfix/private/auth",0, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else { $out = "$authstr\r\n"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } ?> ----------------------- Dovecot auth complains about syntax It seems 'auth mech' also is required. thus; how to correctly use dovecot client auth socket to authenticate? (some FAQ?, php sample code?) 2. [most important] dovecot LDA uses auth maser sockets to read userdb and get home directory path to deliver mail and locate sieve scripts. I need some home path to locate users sieve script. Wow to obtain it using dovecot auth sockets? Tnx Uldis

[Dovecot] Multiple Mailbox Location
by Giuseppe Giacomini 18 Jan '07

18 Jan '07

Hi, I' m using dovecot v1.0.rc17 on a Centos 4.4 linux box with maildir format. Linux box mounts two LUNs of our Storage Area Network. LUN(a) has been mounted on /home with linux quota enable (small in size , but faster than LUN(b)) LUN(b) has been mounted on /archive with linux quota enable (big in size, but slower than LUN(a) ) I want to create two different private namespaces for our users. The first namespace is used for users' current mail (INBOX,Trash,Sent ....) and is located on faster disk (LUN(a)) The second namespace is used as mail archive. User drags his mail from first namespace to the folders located on the second namespace. This is my namespace definition in dovecot.conf default_mail_env = maildir:/%h/MailDir namespace private { separator = / prefix = inbox = yes hidden = yes } namespace private { separator = / prefix = "#Archive/" location = maildir:/archive/%u/MailDir #hidden = yes } This is the output to NAMESPACE command : 02 namespace * NAMESPACE (("#Archive/" "/")) NIL NIL We have a lot of types of client: Outlook >= 2000, Thunderbird, Eudora 7, Squirrellmail 1.4.8 with different behavior regarding namespace. These are my questions: 1) Is my namespace configuration right? Am I missing something? It is a bit different from that at http://wiki.dovecot.org/Namespaces 2) If I create a folder under the default namespace (i.e. .test under user MailDir) and add the folder name in namespace's subscription , Outlook and Eudora show me the folder and if I open the subscribe menu' they show me the two namespaces with their folders. With Thunderbird I can't see the created folder under default namespace and if I open the subscribe window I can see only the second namespace "#Archive" (That one not hidden). Is it a Thunderbird problem? Thank you

[Dovecot] dovecot-auth file descriptor usage
by Steven F Siirila 17 Jan '07

17 Jan '07

In dovecot-auth (rc15) we experienced problems when the file descriptors reached 256 (due to a Solaris fdopen() call described previously). The issue was that there was one file descriptor being used for every imap-login and pop3-login process (in our environment of SSL-only that means one for every active IMAP and POP connection). Mods were made (and appear in rc16) to close out the descriptor in question after using it during authentication (as I understand it). However, I am still seeing plenty of file descriptors left open in rc16 (one per session). For example, on a Solaris 9 server with 9 IMAP connections open here is an lsof excerpt of dovecot-auth: dovecot-a 26071 root 7u unix 105,136 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3000d084250) dovecot-a 26071 root 8u unix 105,140 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3c9c4227b68) dovecot-a 26071 root 9u unix 105,149 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7680b8) dovecot-a 26071 root 10u unix 105,266 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa765d48) dovecot-a 26071 root 11u unix 105,160 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa7667e0) dovecot-a 26071 root 12u unix 105,255 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x3cbaa769288) dovecot-a 26071 root 13r DOOR 265,0 0t0 50 /var/run (swap) (door to nscd[7752]) dovecot-a 26071 root 14u unix 105,258 0t79 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30002dc4008) dovecot-a 26071 root 15u unix 105,282 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185738) dovecot-a 26071 root 16u unix 105,141 0t80 3190 /devices/pseudo/tl@0:ticots->/var/opt/dovecot/run/dovecot/login/default (0x30003185ac8) With the modification made, shouldn't these no longer accumulate? -- Steven F.

[Dovecot] Dovecot cannot find passwd-file
by craig carriere 17 Jan '07

17 Jan '07

Posted this once before, but am still having problems. I have dovecot 1.0 rc15 running with postfix 2.3 on a SLES 10 server. With local user and /etc/passwd /pam authentication my local user can retrieve mail. I am now adding a virtual domain and have postifx relaying correctly. I want to have dovecot pull passwd and userdb from two files. When setting passwd-file to /etc/dovecot/passwd the system states that the file does not exist but it does. It does not appear to be a permissions issue; is this a path issue relative to chroot? Would appreciate some input; I have found others with the same issues but have not seen a solution posted.

[Dovecot] Index corruption causes child process to die
by Juha Saarinen 16 Jan '07

16 Jan '07

My recent migration from Courier-IMAP to Dovecot has been marred by these errors: Oct 24 12:12:40 server dovecot: IMAP(juha): Fixed index file ~user/Maildir/.Geekzone/dovecot.index: first_recent_uid_lowwater 431 -> 430 Oct 24 12:12:40 server dovecot: IMAP(juha): Corrupted index file ~user/Maildir/.Geekzone/dovecot.index: Duplicate header extension keywords Oct 24 12:12:40 server dovecot: child 5786 (imap) killed with signal 11 They happen with Thunderbird 1.5.0.7 and I'm using Dovecot 1.0RC7 from the FreeBSD ports. I think the index corruption may be caused by Tbird's message filtering - I'm asking it to filter certain messages from INBOX to subfolders. When the error occurs, Tbird pops up an error message saying it can't connect to the mail server, but I don't lose any messages it seems. Instead, I get duplicates and even triplicates when I restart Tbird. Any work around for this? -- Juha http://www.geekzone.co.nz/juha
