[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. I think the real problem is that quota_default_alloc() is getting called twice. 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] more unexpected results from 0.99.13 -> 1.0beta8 upgrade
by Alan Premselaar 15 May '06

15 May '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Just to give some more information about this: Apparently some of our POP3 users are saying that when they checked for new mail this morning that all the mail that was saved on the server was downloaded again as unread mail. I followed the guidelines in the wiki [1] with regards to upgrading from 0.99 to 1.0, made sure the .subscriptions and .customflags files were renamed to subscriptions and dovecot-keywords respectively yet the subscriptions were not maintained (i.e. users had to re-subscribe after the update) here's my config information, can you give me any hints as to what went wrong?

[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-----
