[Dovecot] Thunderbird 1.5 and messages with no Date: header
by grant beattie 24 May '06

24 May '06

hi, some of my Thunderbird users have a minor but annoying problem with messages that have no Date: header. these clients use BODY[HEADER.FIELDS (Date)] as the date for messages. when a message has no Date: header, they display the date as 01/01/1970 10:00:00 because Dovecot returns empty string. would it be possible for Dovecot to return INTERNALDATE instead, for messages that contain no Date: header? I know this is not *technically* correct, but it's a reasonable best-guess, and better than returning nothing. perhaps as a client-workaround? I vaguely recalled a previous message about this, but I couldn't find it today. grant.

[Dovecot] Shared folder (namespace) access hanging
by Jeff Turner 24 May '06

24 May '06

Hi, I'm using Dovecot 1.0-b8. We use a shared 'support' account for incoming support mail. For security reasons we want to instead have everyone with their own account, accessing a shared 'support' folder. So I've configured dovecot with a public 'Support' namespace: default_mail_env = maildir:/imap/mailboxes/%u namespace private { separator = / prefix = inbox = yes } namespace public { separator = / location = maildir:/imap/mailboxes/support:CONTROL=/imap/mailboxes/%u/shared-settings/support/control prefix = Support/ hidden = no } So now: - User 'support' logs in (this is the user whose folder is being shared). Dovecot creates a dovecot-uidlist file: root@redback:/imap/mailboxes/support/.INBOX.test# cat dovecot-uidlist 1 1147757548 9 1 1147755677.P8078Q3M183587.redback.sydney.atlassian.com:2,RSace 2 1147755677.P8078Q2M183587.redback.sydney.atlassian.com:2,abcdf 3 1147755677.P8078Q1M183587.redback.sydney.atlassian.com:2,Sabcd 4 1147756077.P8078Q8.redback.sydney.atlassian.com:2,Sabcd 5 1147756440.P8461Q3M643698.redback.sydney.atlassian.com:2,Sa 6 1147756440.P8461Q2M643698.redback.sydney.atlassian.com:2,Sa 7 1147756440.P8461Q1M643698.redback.sydney.atlassian.com:2,Sa 8 1147756440.P8461Q0M643698.redback.sydney.atlassian.com:2,Sa root@redback:/imap/mailboxes/support/.INBOX.test# ls -la total 60 drwxrwx--- 5 jturner mail 4096 May 16 15:32 . drwxrwxrwx 59 support mail 4096 May 16 15:31 .. drwxrwx--- 2 jturner mail 4096 May 16 15:18 cur -rw-rw-rw- 1 support mail 448 May 16 15:32 dovecot.index -rw-rw-rw- 1 support mail 21504 May 16 15:32 dovecot.index.cache -rw-rw-rw- 1 support mail 512 May 16 15:32 dovecot.index.log -rw------- 1 support mail 72 May 16 15:28 dovecot-keywords -rw-rw-rw- 1 jturner mail 0 May 16 14:52 dovecot-shared -rw-rw-rw- 1 support mail 516 May 16 15:32 dovecot-uidlist drwxrwx--- 2 jturner mail 4096 May 16 15:01 new drwxrwx--- 2 jturner mail 4096 May 16 15:14 tmp root@redback:/imap/mailboxes/support/.INBOX.test# - If I now log in as 'jturner' and subscribe to this folder, there appears to be nothing in the 'test' folder.

Is anyone actually *using* shared folders? :) Thanks, Jeff

[Dovecot] IMAP Folder Creation
by Zach Hobbs 23 May '06

23 May '06

I am using Maildir with dovecot 0.99.14-1 and postfix. My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders. Then something changed, and I lost all my folders that contained sub-folders. And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders. The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything. Here's an example file structure (logging in as "zta-tech_zach"): Maildir# ls -lA -R .: total 32 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:41 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:16 .customflags -rw------- 1 zta-tech_zach web1 52 2006-05-22 21:40 dovecot-uidlist drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:16 .INBOX drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 new -rw------- 1 zta-tech_zach web1 6 2006-05-22 21:41 .subscriptions drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 tmp drwx------ 5 zta-tech_zach web1 4096 2006-05-22 21:25 .Trash ./cur: total 20 -rw------- 1 zta-tech_zach web1 16591 2006-05-22 21:40 1148352021.3157_1.www.zta-tech.com:2,S ./.INBOX: total 24 -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:41 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:16 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:16 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:16 .imap.index.tree ./new: total 0 ./tmp: total 0 ./.Trash: total 40 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:25 .customflags -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:24 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:25 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:25 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:25 .imap.index.tree drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 new drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 tmp ./.Trash/cur: total 0 ./.Trash/new: total 0 ./.Trash/tmp: total 0 Thanks, Zach

[Dovecot] Dovecot IMAP not putting size in maildir filenames
by Bill Boebel 23 May '06

23 May '06

I notice that when you move a message from one maildir folder to another, Dovecot drops the size information ("S=") from the filename. Dovecot also does not add the size info to filenames after it gets it via stat(). Shouldn't Dovecot add the size info to the filename so that "maildirsize" recalculations are fast? Bill

[Dovecot] two concurrent dovecots

Hello, Is it safe to have two concurrent dovecot processes to access the same maildir? I have a stock RHEL version (0.99.11) used by users, but I also want to test 1.0-beta together wth postfix for SASL. Is it safe to access the same maildir concurrently with both dovecots (say, the old one via webmail and the new one via remote client)? Thanks, Alex

[Dovecot] Dovecot/LDAP problem
by Burton Simmons 19 May '06

19 May '06

Dear Dovecot mailing list people - What I'm trying to do is use Postfix (with virtual users) and a POP3 server (we don't want IMAP - don't ask) to work against our new Active Directory servers that will be coming soon. Before we roll anything out we're testing it in the lab. Here's what we've got: x86 server running Red Hat Enterprise Linux 3 Postfix 2.0.16 Dovecot-1.0 Beta7 Windows 2003 server running Active Directory Windows XP client running Outlook Eventually, we'd like the clients to be joined to the AD domain and that's where we'll store ALL the user information. The email will come in on our postfix server (which uses virtual users) and the clients will check it passing their email username and domain password. The catch is that USERS CAN BE ANYWHERE IN THE DIRECTORY. (I apologize for the caps, I wanted to make sure that phrase wasn't glossed over.) So, for instance: > DC=local | >DC=domain | >OU=group1 | | | > CN=user1 | > CN=user2 | >OU=group2 | | | > CN=user3 | > CN=user4 | >OU=group3 | >CN=user5 The path to user1 is therefore CN=user1,OU=group1,DC=domain,DC=local (at least in the AD world.) The path to user3 is CN=user3,OU=group2,DC=domain,DC=local. So to search for users I would think (because this is how Postfix does it) that I could have the search base as DC=domain,DC=local and then have scope = subtree. IT DOESN'T WORK. (Again, caps used for emphasis only.) Here's the meat of the dovecot-ldap.conf file I'm using: hosts = 192.168.x.x dn = cn=Administrator,cn=Users,DC=domain,DC=local dnpass = xxxxx auth_bind = yes ldap_version = 3 base = DC=domain,DC=local scope = subtree user_attrs = sAMAccountName,mail,,,, user_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) pass_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) user_global_uid = 44 user_global_gid = 44 --- Interestingly, if I simply point the base to the actual user's container, it works just fine. The idea works from Postfix, but from dovecot it doesn't actually seem to search the tree. --- Here's some of the output from the log files. dovecot: May 17 15:35:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip= 192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:35:52 Info: auth(default): ldap(user1, 192.168.0.195): bind search: base=DC=LAB,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:36:52 Info: pop3-login: Disconnected: Inactivity: method=PLAIN, rip= 192.168.90.195, lip=192.168.90.199 dovecot: May 17 15:37:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:37:52 Info: auth(default): ldap(user1,192.168.0.195): bind search: base=DC=domain,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): master in: REQUEST 1 25233 1 dovecot: May 17 15:37:54 Info: auth(default): ldap(user1,192.168.0.195): base=DC=LAB,DC=local scope=subtree filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) fields=sAMAccountName,mail,,,, dovecot: May 17 15:38:52 Info: pop3-login: Disconnected: Inactivity: user=<user1>, method=PLAIN, rip=192.168.0.195, lip=192.168.0.199 Can anybody offer any insight?

[Dovecot] configure change for 1.0.beta8
by Tomi Vainio 19 May '06

19 May '06

Hi, I'm trying to compile dovecot under Solaris 10 with native Mysql support. Couple changes are needed before configure can detect and compile mysql support. Native Solaris Mysql is installed under /usr/sfw directory. Configure can't find libraries and when these are found -R runtime path is needed for linking. Also if library name is given before library path it can't find it. These changes are needed for configure script line 29533 for i in /usr /usr/local /usr/local/mysql /usr/sfw; do line 29548 LIBS="$LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29559 LIBS="$LIBS -lmysqlclient" line 29770 SQL_LIBS="$SQL_LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29780 LIBS="$LIBS -lmysqlclient" Tomppa

[Dovecot] Outlook Express / POP Problem?
by Marc Perkel 19 May '06

19 May '06

I have a new user who is using Outlook Express with POP and seems to be having a problem downloading messages with attachments. Watching the logs it starts to download and then disconnects. When I use squirrelmail which is IMAP it all looks good so it's not a corrupt mailbox. I'm running Beta8 and using MBOX files. The problem seems to be related to POP and/or Outlook. Has anyone run into this before?

I don't think this is the correct fix below, but it did the trick in our environment when maildir_copy_with_hardlinks=yes.

Once from somewhere in mail_storage_copy() -> maildir_copy() -> mailbox_save_init(), and a second time somewhere after that. src/lib-storage/index/maildir/maildir-copy.c @136 < if (mbox->storage->copy_with_hardlinks/* && < mail->box->storage == mbox->ibox.box.storage*/) { --- > if (mbox->storage->copy_with_hardlinks) {

[Dovecot] Building 1.0beta8 on Solaris
by Matthieu Herrb 18 May '06

18 May '06

The following patch is needed on Solaris, because <sys/stat.h> has a specific macro definition for struct stat. Without this patch the prototype for nfs_safe_stat() changes between the inclusion of nfs-workarounds.h and the definition of the function. -- Matthieu Herrb

[Dovecot] maildir-tags
by Marten Lehmann 18 May '06

18 May '06

Hello, I configured my MTA to store messages in maildirs with a tag "S=$message_size", so quota calculations can be done without stat()ing the message file. However, I have a lot old messages, than haven't been stored with this tag. Is it possible to configure dovecot so that it will rename each file adding this messagesize-tag if it is not found in a file already? You can find more on this at http://www.exim.org/exim-html-4.62/doc/html/spec_html/ch26.html#id2634917 Regards Marten

[Dovecot] Horde/IMP setup

does anyone else use Horde/IMP that can share their servers.php setup? I am getting weird behavior with IMP not showing my INBOX and sub folders, etc. and i am not sure if its an IMP issue or Dovecot. It was giving me problems yesterday, then it cleared up, but now its acting up again. mail clients like Thunderbird work fine tho. I am seeing this in the logs a lot: [Tue May 16 08:08:21 2006] [error] [client 67.133.211.52] PHP Warning: Invalid argument supplied for foreach() in /usr/local/www/horde/imp/lib/IMP.php on line 1197, referer: https://mikestammer.com/horde/services/portal/sidebar.php Line 1197 looks like this: foreach ($_SESSION['imp']['namespace'] as $key => $val) { if (!empty($key) && (strpos($mailbox, $key) === 0)) { $cache[$key][$mailbox] = $val; return $val; } } Anyone have any tips or ideas?

[Dovecot] Authentication Daemons
by Scott Penrose 16 May '06

16 May '06

Hi ho. My name is Scott Penrose - and I am experimenting with Dovecot as an IMAP replacement in our company. I have spent some time trying to write a plugin (sort of) for authentication and come to the conclusion that our instance is a little strange. So I though I would try plan B which is to write my own authentication module. This seems to have worked fairly well to start with but I have had some problems. For example, when connecting with a simple socket client (I have a socket client equiv of telnet) I see the VERSION, MECH ... DONE from the login/default socket, but nothing from the master socket. Both should be returning VERSION. Any ideas on that one? Thanks Scott

[Dovecot] Dovecot + Sendmail + virtusertable
by Chris Tata 16 May '06

16 May '06

Hello, I was wondering if there was a way to have dovecot authenticate using sendmail's virtusertable to map virtual users to system users. My goal is to allow virtual users (bob(a)domain.com) to authenticate via pop or imap using the full user@domain scheme. I tried enabling 'vpopmail' as passdb and userdb in the default namespace but I get this error: dovecot: May 15 23:05:21 Error: auth(default): Unknown passdb type 'vpopmail' Please advise. Thanks, Chris

[Dovecot] Missing mails after folder renaming
by Bob & Sabine von Knobloch 15 May '06

15 May '06

Dear List, I seem to have created myself a problem to which I can't find an answer. I am using Dovecot (0.99.13-4.FC2 on Fedora Core 2) with Mozilla Thunderbird on Windows XP and Linux as IMAP client software. I renamed a folder to a name that included spaces (it fitted the pupose better), then later realised that I would have to change my procmail rules to suit. As I wasn't sure what procmail would do with such folder names I renamed the folder back to it's original short name (all this changing was done in Thunderbird). The result is that all subfolders under the renamed folder exist in both forms: eg "Computer.SubjectA" and "Computer Projects.SubjectA", but the second versions are not seen by Thunderbird although they contain all my old mails (new mails are correctly delivered to the short name folders). I have tried to move the mails in these folders back to the short name folders but the indexing system (I assume) does not 'see' these maildir files. How can I fool the system into seeing all the old mails? Of course, I would like to know why the second renaming didn't work but don't have enough information to know if it's Thunderbird or Dovecot that isn't working correctly. As a second question, my Windows clients run in an NT domain (Samba) with roaming user profiles. The pathnames for some users become quite long and Windows throws a 'path too long' error when saving/loading the user profile from the DC. Is there a way of limiting the depth of folder nesting under Dovecot to avoid this problem? I have tried to search for answers but haven't found any yet. If there is already some information, I would be glad of a pointer to it. I am very pleased with the performance of Dovecot in all respects, thanks for the program. Bob von Knobloch.

[Dovecot] Anyone using Dovecot LDA on OS X?
by Dean Blackburn 15 May '06

15 May '06

I'm curious if anyone can get the LDA running on OS X, and what their experiences have been... We are still having index corruption issues that result in many temp files being created and client-side timeouts using a straight Postfix local delivery under 1.0beta7. The LDA does not come packaged with the Darwinports version of Dovecot, so any tips on compiling it would be most appreciated... Thanks, -deano

[Dovecot] dovecot ldap auth bind and different directories
by Andrew Bates 15 May '06

15 May '06

I have recently begun playing with Dovecot (1.0.beta8) and have run into an interesting scenario. The way my email system is set up is that users of different domains have completely different base dn's. For instance, if a user is part of test.com the bind dn would be uid=user,ou=People,dc=test,dc=com. The bind dn for user(a)domain.com would be uid=user,ou=People,dc=domain,dc=com. I could not seem to figure out a way to have the binddn adjusted based on a user's @domain so I modified auth-request.c and var-expand.c to include a new variable expansion concept. In the configuration I'm now able to include the following: auth_bind_userdn = uid=%n,ou=People,dc=%c2,dc=%c1 and %c1 will be expanded to the tld, %c2 will be expanded to the next level domain (domain or test in the above example). This will work up to 9 levels of subdomain (1-9). This is very similar in how postfix expands variables with ldap. I'm a bit rusty with my C, so I'd love some feedback on the patch. If this idea isn't included in the main code, that's fine, but I thought I'd contribute my experiences! Thanks for a great product everyone!

[Dovecot] re: ssl-build-param
by Jackie Hunt 15 May '06

Hi all, I posted a message last week about a problem with ssl-build-param, shown below. I may have a lead on this, and was hoping someone can confirm my theory. On AIX, a malloc of 0 bytes returns NULL, which is different than on Solaris and HP-UX (and probably Linux?) I'm guessing the NULL pointer returned is causing the abort of the ssl-build-param, since that was an unexpected result. Looking briefly at the code in ssl-init-openssl.c that seems reasonable. Can anyone please confirm this? And if so, any suggestions on the best way to proceed?

[Dovecot] dovecot and vmailmgr
by Mij 15 May '06

15 May '06

hello now that dovecot supports authentication with checkpassword-compatible modules, I tried to get it working for IMAP on a qmail + vmailmgr server. For a subtle detail, while claiming to be "a drop-in replacement for the standard checkpassword", checkvpw (auth module for vmailmgr) is not "drop in". It actually expects 2 args on its command line, not 1. So, a wrapper is needed to get it authenticating correctly with dovecot; a very simple one (argswrapper.c below). This wrapper is not sufficient though. In fact, vmailmgr represents user homes like this: $HOME_LOCUSER/users/virtual_username this is ok with default_mail_env = maildir:%h/users/%n $HOME_LOCUSER depends on the domain part of the user's email. The relation is held in /var/qmail/control/virtualdomains . However, on the local part (virtual_username) some rewriting is done on the username, as dots are replaced by ":". So in the end j.doe(a)foo.com becomes "~mxfoocom/users/j:doe". Now, var-expand does not support any rewriting. I patched it by adding another modifier, m_str_replace(), which replaces REPLACE_SOURCE with REPLACE_TARGET in a given string. By defining REPLACE_SOURCE to '.' and REPLACE_TARGET to ':' one accomplishes the vmailmgr username rewriting. This modifier is applied with "P", so: default_mail_env = maildir:%h/users/%Pn A better, general solution would be for dovecot to implement some kind of general rewriting, say with regexps and sed-like replacement rules, or with an external process in a cgi fashion. With this patch, dovecot gets the correct path for any user mailbox. However, there's a bug in dovecot storage modules (both maildir and mbox) which truncates the path in the first ":", when expecting ":INBOX" etc specifiers: /* <Maildir> [:INBOX=<dir>] [:INDEX=<dir>] [:CONTROL=<dir>] */ if (debug) i_info("maildir: data=%s", data); p = strchr(data, ':'); if (p == NULL) root_dir = data; else { root_dir = t_strdup_until(data, p); this way, a former data = /var/maildirs/foo/users/j:doe:INDEX=... is truncated to /var/maildirs/foo/users/j . This opens the much worse possibility for user "j:doe" to be accounted into user "j" account after authentication. It is difficult to get a solid fix here, because the grammar is ambiguous for INBOX, INDEX and CONTROL tokens. Since they are not separated with an illegal path symbol from the rest of the path in default_mail_env, it is not possible to state when a ":INBOX=" token belongs to the path and when it is a user directive. The Best is to move the specifiers into a different configuration directive. However, a more solid check with the current modus operandi is /* <Maildir> [:INBOX=<dir>] [:INDEX=<dir>] [:CONTROL=<dir>] */ if (debug) i_info("maildir: data=%s", data); /* extracting INBOX / INDEX / CONTROL suffices */ if (((p = strstr(data, ":INBOX=")) != NULL) || ((p = strstr(data, ":INDEX=")) != NULL) || ((p = strstr(data, ":CONTROL=")) != NULL)) { root_dir = t_strdup_until(data, p); which expects the full ":INBOX=" etc strings to be present in data instead of the single ":" separator. The patches that implement this for both {maildir,mailbox}-storage are also appended below. I will take a couple of hours tomorrow to wrap all the iter up on a web page here http://mij.oltrelinux.com/net/dovecot-qmail-vmailmgr/ All the patches are applied wrt 1.0-beta7 bye

[Dovecot] Semi-OT: Backing up maildir
by Shayne Hardesty 15 May '06

15 May '06

We switched our mail server over from mbox to maildir a few months ago and couldn't be happier - the performance under normal load is incredible. However we now have a problem with backup.. Typically we would run tar on the mail server, sending its output to another server via ssh.. Like this: tar cfp - /home | gzip | ssh other.server (cd /backups && tar xfp -).. I have tried gzipping the stream on the source side, gzipping on the destination, and running without gzip, all three take an amazingly long time to complete (> 14 hours). Ours is a modest server with about 1300 users, about 300GB of mail total. The whole thing sits on hardware RAID-10, so I'm primarily guarding against a MAJOR hardware failure, a config blunder, or a hacker wiping out files. How do you guys back up your maildir? I've considered exporing the maildir with NFS and backing it up from another server.. Any opinions on that? Thanks, Shayne

[Dovecot] 1.0beta8 won't start: Fatal: Protocol imaps given more than once
by Mike Brudenell 15 May '06

15 May '06

Greetings - I've just built Dovecot 1.0beta8 and find it refuses to start. This under Solaris 10 on an Intel-based Sun system. The error message Dovecot displays (on standard error) in response to /usr/local/sbin/dovecot is Fatal: Protocol imaps given more than once I've checked through my configuration file and the only mention of "imaps" is here: # Protocols we want to be serving: # imap imaps pop3 pop3s protocols = imap imaps The same settings file worked OK with 1.0beta7. I've also tried using the standard dovecot-example.conf that comes with 1.0beta8 which has the "protocols" line commented out and, after adding appropriate settings for "ssl_cert_file" and "ssl_key_file", still have the same problem. I popped a few dubugging i_info() calls into src/master/main.c to try and see what was going on and the output was as follows: Info: set->protocols = >imap imaps< Info: imap: *fd = -1 Info: imaps: *fd = 0 Fatal: Protocol imaps given more than once The first line is displaying the value of the keywords in set->protocols The second and third are within the if/then/else sequence: the first for the "imap" keyword and the second for the "imaps" keyword. Then comes the fatal error, caused by the "fd" variable not being equal to -1 (it is "0" for "imaps") above. Changing the dovecot.conf file to read protocols = imap lets Dovecot start up OK. Changing it to protcols = imaps causes it to fail in the same way as before(!). Seems to be a problem with the initialisation of set->ssl_listen_fd therefore, as this should apparently be -1? Is this likely to be something I've got wrong (wouldn't have thought so as 1.0beta7 is happy with the same config file) or is there a problem in 1.0beta8?

[Dovecot] FSF - dovecot
by Matt 14 May '06

14 May '06

Will dovecot always be open FREE source for all? I am currently migrating my www.digipanel.com from Courier to dovecot as I think courier is overly complicated and a pain in the arse to manage all those files. anyways, I have dovecot IMAP working with MySQL auth but reading the Maildir each time takes up to 30 secs to complete. ANy ideas why? Maybe a dns resolve issue? how can I fix..

[Dovecot] problems with 1.0beta[78] on RHEL3
by alan premselaar 14 May '06

14 May '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been running 0.99.13 on RHEL 3 for over a year now and finally decided to upgrade to the 1.0 series. unfortunately, I only have one RHEL 3 machine which is my production machine. So, while doing all my preliminary testing I was doing so on a FC 3 machine. I got everything to a stage where I felt comfortable doing the upgrade but I'm running into some problems on the RHEL 3 system. if I download the tarball, it compiles without problem. If I download the cvs or the src.rpm then I get autoconf errors complaining about not supporting AC_CONFIG_HEADER but requiring AM_CONFIG_HEADER. it also complains that the installed version of autoconf is too old, although it's the latest package for RHEL 3 (which means it has the same version number as the original installed package but all the updates are back-ported to it, right?) anyways, that's all trivial as the source compiles. the problem I'm running into is this: the quota plugin is returning the following errors in the mail log: May 13 02:02:13 mail dovecot: POP3(real_user): dlopen(/usr/lib/dovecot/pop3/lib01_quota_plugin.so) failed: /usr/lib/dovecot/pop3/lib01_quota_plugin.so: undefined symbol: mount point_get and also: May 13 02:03:03 mail dovecot: IMAP(real_user): quotactl(Q_GETQUOTA, /dev/sdb1) failed: Invalid argument can anyone offer any assistance with this? oh yeah, one last thing. following the wiki, during the upgrade i renamed the .subscription files to subscription in each user's Maildir directory (oh yeah, i'm using maildir format) but, the subscription information wasn't persistant. anything else i need to be aware of related to that? thanks alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEZMCtE2gsBSKjZHQRAjRVAKCPgSxLQzyJ7lrhCYBSxnVeTJixtgCaA8G5 NtAoCZZWpdetBLGQsA0llrU= =K+09 -----END PGP SIGNATURE-----

[Dovecot] SASL bind for LDAP
by Geert Jansen 13 May '06

Hi, would it be possible to add support for SASL binds to dovecot's LDAP userdb/passdb? This would be a nice feature as it would allow the use of SASL EXTERNAL binds to a local LDAP server, thereby removing the need for storing clear-text passwords in configuration files. Regards, Geert

[Dovecot] LDA Sieve feature request
by Luca Corti 13 May '06

13 May '06

Hello, In http://wiki.dovecot.org/LDA I read # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = so you can set global_script_path and override it using a per user script. It would be nice if the per user scripts could be optionally run after (or before maybe?) the global script. Another nice thing would be per-virtualdomain sieve scripts, but I think this is much more difficult.

[Dovecot] 1.0.beta8 released
by Timo Sirainen 12 May '06

12 May '06

Next release will probably be called 1.0.rc1. People just don't seem to like the beta name in the version number. :) Also I think we're nearing the final v1.0. * Fixed a security hole with mbox: "1 LIST .. *" command could list all directories and files under the mbox root directory, so if your mails were stored in eg. /var/mail/%u/ directory, the command would list everything under /var/mail. + Unless nfs_check=no or mmap_disable=yes, check for the first login if the user's index directory exists in NFS mount. If so, refuse to run. This is done only on first login to avoid constant extra overhead. + If we have plugins set and imap_capability unset, figure out the IMAP capabilities automatically by running imap binary at startup. The generated capability list isn't updated until Dovecot is restarted completely, so if you add or remove IMAP plugins you should restart. If you have problems related to this, set imap_capabilities setting manually to work around it. + Added auth_username_format setting - pop3_lock_session setting wasn't really working - Lots of fixes related to quota handling. It's still not working perfectly though. - Lots of index handling fixes, especially with mmap_disable=yes - Maildir: saving mails could have sometimes caused "Append with UID n, but next_uid = m" errors - flock() locking never timeouted because ignoring SIGALRM caused the system call just to be restarted when SIGALRM occurred (probably not with all OSes though?) - kqueue: Fixed "Unrecognized event".

[Dovecot] userdb prefetch not working with dovecot LDA?

Hello, I've configured MySQL authentication as follows. -- divecot-sql.conf -- driver = mysql connect = host=localhost dbname=postfix user=myuser password=mypass default_pass_scheme = PLAIN password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT CONCAT('/var/vmail/', maildir, 'Maildir') AS home, '1234' AS uid, '1234' AS gid FROM mailbox WHERE username = '%u' -- dovecot.conf -- passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } And both access (IMAP) and delivery (LDA) work correctly. Now I want to setup prefetching to reduce SQL queries, so I did -- dovecot-sql.conf -- driver = mysql connect = host=localhost dbname=postfix user=myuser password=mypass default_pass_scheme = PLAIN password_query = SELECT password, CONCAT('/var/vmail/', maildir, 'Maildir') AS userdb_home, '1234' AS userdb_uid, '1234' AS userdb_gid FROM mailbox WHERE username = '%u' -- dovecot.conf -- passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb prefetch { } Dovecot mail access (IMAP) works correctly, but when the LDA tries to deliver mail I get: May 11 16:25:00 ns1 dovecot: auth(default): prefetch(luca(a)example.com): passdb didn't return userdb entries May 11 16:25:00 ns1 postfix/pipe[11040]: 21E31847BC: to=<luca(a)example.com>, relay=dovecot, delay=0, status=bounced (user unknown) thanks -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: user to computer ration too low.

[Dovecot] dovecot-lda and sieve filtering (SMTP is Postfix)
by Der Olli 12 May '06

12 May '06

Hello list. I've got a working Dovecot with Postfix and MySQL-support but everything from the capabilities of sieve isn't working except one thing: Sorting emails to folders works fine. But no vacation, no reject, no redirect. I don't get any errors in the logs. Verbose logging is enabled. I compiled both from newest cvs-sources but also tried older combinations (nightly snapshots). Always the same result and there's no .dovecot.sieve.err so script is okay. If it is not, .dovecot.sieve.err will be generated. I've tested this :) Anyone here who has a working sieve implementation with dovecot-lda? Where do I have to search? Is it a configuration problem? Where can I configure which sending mechanism dovecot-lda should use? Is it a local sendmail binary? Where does dovecot-lda search for it. Is it a SMTP-server? So there's one on port 25 at the local machine. Greetz, Olli

[Dovecot] comment on dovecot documentation on PAM
by president＠irithm.com 12 May '06

12 May '06

Dear Dovecote devotees, I have been going through dovecot configuration for the first time. I am not an experienced systems administrator so I had to do a left turn to read up about PAM while doing all the configuration for my new webmail service. I found that the writing in the dovecot documentation about PAM to be rather misleading in at least one aspect. The documentation I am specifically referring to is at http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 and in the comments found in the dovecot.conf file. In this documentation PAM is referred to as a password database. It appears that is not correct, rather PAM is something that uses a password database. Since the default for "auth_passdb" given in dovecot.conf was "pam" I spent sometime trying to find a pam password database. I eventually found out at an independent website that what pam uses is either /etc/passwd or /etc/shadow or /etc/samba/smbpasswd. It was a relief to find out pam uses one of these, since my system has one of them (/etc/shadow), but I was looking to find something quite different for pam since /etc/shadow is one of the listed alternative values for "auth_passdb". I would have been spared a somewhat lengthy search to find out this information if the documentation was written rather more clearly. So, to help others, I suggest changing the following lines in dovecot.conf # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: PAM authentication to: # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: /etc/shadow or similiar, using PAM authentication Updating the documentation in http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 to include a phrase that mentions that PAM authentication works from one of the standard password databases (i.e. /etc/passwd, /etc/shadow or /etc/samba/smbpasswd) would also be helpful. yours sincerely, Rolf

Hi all, Another user posted the same thing a few months back... after contacting them, they said they never got it working. I'm unable to get Pocket Outlook, or FlexMail 2006 working on Dovecot 0.99.13. According to the logs it connects just fine. With Pocket Outlook I'll see the headers for a few seconds, and then it clears and shows nothing.

[Dovecot] mandatory client certificates and crl check in ssl-proxy-openssl.c
by HenkJan Wolthuis 11 May '06

11 May '06

hello, I made a modification to ssl-proxy-openssl.c (patch attached) zo that it a) disconnects when no client certificate is presented b) checks the client certificate against the crl for our root cert. (so you can't use a revoked client cert.) c) returns the CommonName from the client cert. in ssl_proxy_get_peer_name (this way it's easier to use dovecot as imap-proxy with a passwd-like userdb, ssl_require_client_cert and ssl_username_from_cert, it "binds" the emailuser to the clientcertificate, a clientcert. can access only the account from the userdb) in order to use it, the CAfile must be a file which contains the CAcertificate (pem format) followed by the CRL (also in pem format). (servercert and the clientcerts are signed with a self-signed rootcert) there are some issues with the patch: a) it needs openssl > 0.9.7 for the CRL checking b) ssl_verify_client_cert now returns 0 in case of an invalid cert. was there a reason why it always returned 1? c) i'm not too happy with the commonname extraction code, is it secure?? d) i've no experience with programming openssl or dovecot e) i haven't programmed in C for at least 8 years...... does anyone here have more issues, corrections, comments on the patch? can/should this functionality be implemented in dovecot?
