[Dovecot] ldap: No password in reply

21 Sep '05

Greetings, I'm trying to set up dovecot with ldap (and postfix) by following the page on the wiki. I configured everything, but something is wrong: dovecot: Sep 21 12:03:59 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=157.193.40.36 rip=157.193.44.68 dovecot: Sep 21 12:03:59 Info: auth(default): client out: CONT 1 dovecot: Sep 21 12:03:59 Info: auth(default): client in: CONT 1 b2xlX3dvYmJsZQBvbGVfd29iYmxlAHdvYmJsZQ== dovecot: Sep 21 12:03:59 Info: auth(default): ldap(ole_wobble,157.193.44.68): base=ou=accounts,dc=zalm,dc=UGent,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=ole_wobble)) fields=uid,userPassword dovecot: Sep 21 12:03:59 Info: auth(default): ldap(ole_wobble,157.193.44.68): uid(user)=ole_wobble dovecot: Sep 21 12:03:59 Error: auth(default): ldap(ole_wobble,157.193.44.68): No password in reply dovecot: Sep 21 12:03:59 Info: auth(default): client out: FAIL 1 user=ole_wobble temp dovecot: Sep 21 12:04:01 Info: imap-login: Disconnected: user=<ole_wobble>, method=PLAIN, rip=157.193.44.68, lip=157.193.40.36, TLS This is my database: dn: dc=zalm,dc=UGent,dc=be objectClass: top objectClass: dcObject objectClass: organization o: Universiteit Gent dc: zalm dn: cn=admin,dc=zalm,dc=UGent,dc=be objectClass: simpleSecurityObject objectClass: organizationalRole cn: admin description: LDAP administrator userPassword:: e2NyeXB0fVpsbWpDb21kL3JSbkU= dn: ou=accounts,dc=zalm,dc=UGent,dc=be objectClass: top objectClass: organizationalUnit ou: accounts dn: cn=dovecot,ou=accounts,dc=zalm,dc=UGent,dc=be objectClass: top objectClass: person cn: dovecot sn: dovecot userPassword:: e0NSWVBUfXp6bGxQa1JoV1Nmb00= dn: uid=ole_wobble,ou=accounts,dc=zalm,dc=UGent,dc=be objectClass: top objectClass: person objectClass: posixAccount cn: Ole Wobble Olson sn: Olson uid: ole_wobble uidNumber: 3000 gidNumber: 8 homeDirectory: /home/postoffice userPassword:: e0NSWVBUfXBrOGN6SnlZVG5IL28= dn: uid=ole_wubble,ou=accounts,dc=zalm,dc=UGent,dc=be objectClass: top objectClass: person objectClass: posixAccount cn: Ole Wubble Olson sn: Olson uid: ole_wubble uidNumber: 3001 gidNumber: 8 homeDirectory: /home/postoffice What could be wrong?

[Dovecot] ALL TCP/IP connection REST when one mail contains format error
by Yi Xuan 20 Sep '05

20 Sep '05

Hi, I have setup a dovecot pop3 server on IP_A and using mbox format I have 6 users behind a NATed network, the public IP is IP_B. And one mail of one user seems contain format error. He always cannot receive the 5th mail from anywhere. Then when he receive mail in the intranet, all the TCP/IP connection REST between IP_A and IP_B. http/ssh/pop/smtp etc. all NG. After I delete the 5th mail from webmail, then the services work well. 1.It seems unreasonable, Can dovecot improve it and let it donot influence other users and other service? 2.What may cause mbox format error? and how can we avoid it? Best regards,

[Dovecot] Two strange behaviours with dovecot+postfix+squirrelmail
by Francisco Neira 20 Sep '05

20 Sep '05

Hi all, About a week ago I was forced to migrate my main (production) email server from RH9 to Centos4.1. The installation has dovecot-0.99.11 + postfix-2.1.5 and >600 mbox accessed email accounts. Number 1. Some users accessing thru squirremail (installed in my webserver) can read their INBOX at /var/spool/mail directory but when trying to delete a message they receive the following error message from squirrelmail: ERROR: Could not complete request. Consulta: COPY 1279 "mail/Trash" Reason Given: Internal error occured. Error report written to server log. [2005-09-16 15:08:04] and the error logged is the following: Sep 16 15:09:27 mail imap(username): mkdir_parents(/home/username//mail/.imap/Trash) failed: Permission denied I never stated that .imap/Trash when configuring dovecot and the strangest thing is that my account, as most of others, can delete messages moving from /var/spool/mail/my_name to /home/my_name/mail/Trash Number 2. Randomly, some users connecting from Mozilla Thunderbird via IMAP get an error message telling that there has been an error connecting to INBOX. Watching the maillog I found the following: Sep 16 13:07:43 mail imap(otheruser): File isn't in mbox format: /var/spool/mail/otheruser I accessed the user's inbox file with vi and found that there was a "--604" at the beginning of the file. In other case I found that the file was beginning with a truncated email message. Trying to "walk on the safer side", I changed the mbox_lock setting from "fcntl" to "dotlock" in the /etc/dovecot.conf file. Any suggestions and comments about his will be highly appreciated. Forgive me about my English, it is not my native lanaguage. Regards, -- Francisco Neira B. Administrador de Red Defensoria del Pueblo Lima, Peru, -05:00 UTC

[Dovecot] NO: Unsupported authentication mechanism
by Steve [Dovecot] 19 Sep '05

19 Sep '05

I'm happily using dovecot as my IMAP server and accessing mails using Thunderbird... but I want to use the Net::IMAP facilities in the Ruby standard library to write some scripts to automate various spam-related tasks & housekeeping. My Ruby script: require "net/imap" imap = Net::IMAP.new('localhost') imap.authenticate('LOGIN','myuser','mypassword') # More stuff using imap... From the documentation LOGIN uses plaintext authentication - which I understand is always acceptable for Dovecot when connecting from localhost. On the 3rd line I get a "NO response" exception raised (indicating that the IMAP server replied "NO") and the error message "Net::IMAP::NoResponseError: Unsupported authentication mechanism" If I change 'LOGIN' to 'CRAM-MD5' (the other value supported by Net::IMAP) then I get a similar (but not identical) error: "Net::IMAP::NoResponseError: Authentication failed: Unsupported authentication mechanism" If I use anything other than either 'LOGIN' or 'CRAM-MD5' I get an error from the Net::IMAP library saying "Unknown auth type" - which is reasonable. N.B. I've tried both where 'myuser' and 'mypassword' are valid - and not... this doesn't affect the error messages. There doesn't seem to be anything of interest in /var/log/messages... Can anyone tell me what is going wrong, and how to resolve this?

[Dovecot] FreeBSD port
by David King 19 Sep '05

19 Sep '05

FreeBSD users: I notice that the version of Dovecot in the FreeBSD ports system is back at .99. Are there any objections to my submitting an update to the FreeBSD ports for version 1.0a? Is it better to wait for 1.0 to be progressed a little or is it considered to be ready? 1.0a compiles and seems to run fine (on 5.3), so are there any obvious patches that would be needed for the FreeBSD build? -- Don't forget that 19 September is National Talk-Like-A-Pirate Day! http://www.talklikeapirate.com/piratehome.html

[Dovecot] Very minor feature request
by Steffen Kaiser 19 Sep '05

19 Sep '05

Hello, I'd suggest a way to get to know the "capabilities" of a compiled Dovecot. The background is that I've run the sequence ./configure --with-ldap && make && make install twice, all three commands tell me that all is fine (ldap is listed in the modules), but still dovecot told me that ldap is no Usedb module. A "make clean" before solved the problem -- well, something one should anyway. Besides, the "dovecot --capabilities" should also list all the defaults. Bye, -- Steffen Kaiser

[Dovecot] Newbie question

Hi, my name is Andrés Rusconi, from Tucumán, Argentina. Sorry my English, please. I am a very happy new user of Dovecot: I gained speed and simplicity with him. But I noticed that in clients who use Outlook, the deleted messages do not copy to the trash folder. This is not critical, but did not happen with Courier, and the users askme about this behavior. If some of you has somehow solved this small question, I will thank for their commentary. Saludos Andrés

I wanted to use imapfilter, a program that uses imap to access mailboxes to do that, but as the users can change their passwords, I can't do it. Is there a way to do that?

Refer to server log for more information. [2005-09-12 09:32:49] I've read in the archives that it's the blank line at the beginning of the mbox file, and once deleted everything works fine. The thing is, it keeps happening and I can't figure out why. Email clients that send mail to these accounts are the latest Outlook Express. As I said, I have 150+ users on the same system and they are fine. I'm not sure if protocol makes a difference, but we are using POP3 only. Any ideas what I can do to fix/prevent/correct this either programatically or with a patch of some sort? Is this actively being worked on? I'm running FC4 with dovecot-0.99.14-4.fc4.

[Dovecot] Dual INBOX Locations

G'day list, Just a quick question - I need to configure Dovecot to do the following: * check default_mail_env for the users' inbox in MBOX format * If the above fails, serve the user an inbox from a secondary location, in MAILDIR format. I have read up on Namespaces, however I can't seem to get this to work - login just fails when Dovecot cannot find the inbox in default_mail_env Any advice, anyone? :) Thanks, Calum -- Calum Power Systems Administrator Server101 Pty.

[Dovecot] problems with Auth and Alpha 1a
by Søren Peter Skou 18 Sep '05

18 Sep '05

Hi all I'm not quite sure how to explain this problem, so I'll just go from the top ;-). System is setup on a FreeBSD with IMAP and POP3, both can use PAM and SQL (MySQL) as login methods, though only POP3 is accessible from "the world" - IMAP is restricted via firewall to only localhost. Simple eh? The problem is that dovecot apparently drops the SQL part from time to time. Though this can be fixed by HUPing the dovecotdaemon I'd rather that I didn't have to. I've narrowed the problem to something like this: Over time, Dovecot/POP3/SQL combination dies - I've yet to examine if the problem is on IMAP as well as this is only recently reported. I have never experienced this myself since I'm using Dovecot/IMAP/PAM and this seems to be rock solid. The configuration looks like this: OS: FreeBSD n/a 6.0-BETA3 FreeBSD 6.0-BETA3 #0: MySQL: 5.0.9-beta-log Dovecot: alpha 1 (I'll test Alpha 2 to see if the problem persists) Compilation options for dovecot: ./configure \ --enable-ipv6=no \ --with-ldap=no \ --with-vpopmail=no \ --with-mysql \ --with-ssl=no dovecot.conf: base_dir = /var/run/dovecot/ protocols = imap pop3 ssl_disable = yes disable_plaintext_auth = no login_user = dovecot login_process_per_connection = no login_greeting = Ready max_mail_processes = 1024 first_valid_uid = 1 first_valid_gid = 1 protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } passdb sql { args = /usr/local/etc/dovecot/mysql.conf } userdb sql { args = /usr/local/etc/dovecot/mysql.conf } user = root } -- END -- sql.conf: driver = mysql connect = host=localhost port=3306 dbname=N/A user=N/A password=N/A client_flags=0 default_pass_scheme = CRYPT password_query = SELECT password FROM mail WHERE username = '%n' and domain= '%d' user_query = SELECT concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as home,concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as mail, 1 as uid, 6 as gid FROM mail WHERE username = '%n' and domain = '%d' -- END -- I'm sort of at a loss here since everything "seems to be working" (tm) for one part, but not another Hope someone has an idea ;-) Søren P.

I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] Timeout while waiting for lock....
by Rob Frohne 16 Sep '05

16 Sep '05

Hi, I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing.

Can anyone suggest something to fix my problems, besides deleting all my email? Thanks, Rob

[Dovecot] SSL/TLS stopped working in 1.0 alpha2
by Andy Cravens 15 Sep '05

15 Sep '05

I have both 1.0 alpha1 and alpha2 installed on my test mail server. SSL/TLS does not work on alpha2. I'm using the same config file for both. No errrors in dovecot.log either. Is there a way to increase debugging info without recompiling?

[Dovecot] Dovecot-LDA problems (CVS version) Signal 11 and empty 'mail' dir
by Steffen Kaiser 14 Sep '05

14 Sep '05

Hello, I'm trying dovecot-lda (deliver.c has CVS version 1.18). When I try to deliver a mail, an empty directory is created name $HOME/mail. This is neither the configured (via LDAP) nor the default "mail" setting in the /usr/local/etc/dovecot-deliver.conf. When the $HOME directory does not exist, but the user itself: Sep 1 11:47:12 localhost deliver: mbox: Can't create root IMAP folder /home/skaise2a/mail: Permission denied Sep 1 11:47:13 localhost sm-mta[4684]: j819lCgd004682: SYSERR(root): mailer local died with signal 11 Default mail: mail = maildir:%h/.mailboxes:INDEX=/usr/local/var/spool/dovecot/indexes/%Lu Configured via LDAP for user skaise2a: maildir:/mailcache/skaise2a:INDEX=/var/cache/dovecot/indexes/skaise2a:CONTROL=/var/cache/dovecot/control/skaise2a I have only found the error message in dovecot's src/lib-storage/index/mbox/mbox-storage.c function create_root_dir(). The Dovecot logs indicate that dovecot-lda is requesting the information from it and the message is - once the empty directory could be created - delivered into the configured IMAP root.

Locking _does_ work for postfix and dovecot (discussed with Wietse, partly by mail). Any idea? As an alternative, is there a way of handling the problem better?

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes

Hi everyone: I am seeing a whole LOT of these messages in my dovecot logfile: imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 0 imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 1 and also these: imap(mbwnews): Sep 12 17:10:16 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) imap(mbwnews): Sep 12 17:10:18 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) And not just referring to my inbox, other users as well. I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] An alternate "dovecot-auth" daemon using cyrus-sasl
by buc 12 Sep '05

12 Sep '05

We use dovecot in a heterogeneous environment (Windows/Linux desktops and Linux servers). For unified authentication we use a sheaf "Samba/Openldap" (i.e., Samba NT domain with openldap backend and pam/nss_ldap for Linux). Windows users are authenticated well everywhere, but there is one old issue. As "SPA" (NTLM) against NT domain is not supported by dovecot, it is necessary to use default "plain" method. In addition to security problems, it does also a problem of password unification. Each time a user changes the password, he should do it one more time for the mail program. I know that dovecot supports NTLM, however against local database only (not for NT domain controller). In early versions support of cyrus-sasl (which supports NTLM now) had been incorporated, however it like not work and now is removed. Fortunately, there is a possibility to substitute dovecot-auth executable. Therefore I have tried to make an alternate variant of dovecot-auth, which supports all that we need. For us, it seems to be more useful to create an auth daemon using cyrus-sasl, rather than to add domain support to existing ntlm code. First of all, it is easier for implementation. Besides it enables use of all mechanisms supported by cyrus-sasl (present and future), including GSSAPI. Anyway, it will be the useful additive to dovecot. I have made appropriate patches for both dovecot-1.0-stable and dovecot-1.0.alpha1. The idea is to copy "src/auth" to "src/auth-cyrus", strip all unneeded from newly created directory and add cyrus-sasl support. The resulting code probably looks not so elegantly as if it has been written separately, however this way allows to not make a lot of things from the scratch. The patch against 1.0.alpha1 is here: http://dmitry.butskoy.name/dovecot/dovecot-1.0.alpha1-cyrus.tar.gz . To be more readable, it is not a flat patch (due to a lot of whole files add/remove). It is a tarball with 3 files: a list of files to initial copy from auth/ to auth-cyrus/, a patch for resulting tree, and a script which automates this steps (:-)). (The script should be run in the root of the main source, i.e. a dir with src/ and doc/ subdirs). I already have successfully tested this patch with PLAIN method. However before testing of other methods, it would be desirable that somebody have looked at it. Whether someone could check up my patch (just fluently having read), at least for obvious bugs and typos?

[Dovecot] Dovecot feature request: move /var/mail/uid to INBOX
by Steffen Kaiser 12 Sep '05

12 Sep '05

Hello, UW-Imap has a (questional, but for me useful) feature to slurp all mails pending in /var/mail/uid into the user's INBOX whenever the user successfully logs on and the INBOX is not configured as /var/mail/uid. The usefulness for me is that users have a relatively small quota, so the noisy "over quota" messages pop up for everyone now and then, regardless how frequent one reads the mail. When I now set a large quota for the "pending INBOX", where the user (aka dovecot) can only delete mails from, I circumvent those messages, prevent that users use the (large) INBOX as yet another place to pile up data (the user does not know about the pending INBOX at all) and let the users have "full" control over their folders. The disadvantage is that it works for "real" users only. Another disadvantage is that one would expect "LDA"-features in the server portion of Dovecot, e.g. Sieve :-), or the server would need to spawn the Dovecot-LDA somehow. (Next thing is that, currently, the mails are delivered into the home directory of the users, what leads to several annoyances when someone is away for some time and finds his home directory locked, because the mass of mails locked the directory. Mostover, those IMAP servers I ran so far didn't allowed the user to delete a mail via IMAP often, because some temp or arbitary file couldn't created in the IMAP root. Because the user is already logged on onto Dovecot, there should be less problems deleting mails when the quota exceeds while slurping them in. At least I had extremly good experiences with this mechanism, when I used UW-Imap and the INBOX was located as mbx in the user's homedirectory.) Bye, -- Steffen Kaiser

[Dovecot] reading subfolders with mail.app

Hi all, I have been having a hard time using Fedora Core 4 with dovecot +sendmail. Namely, I cannot read my home dir's procmail filtering dir (where I have some subfolders) in ~/mail. I cannot create mailboxes either. I'm wondering if this is a client issue, and whether I need to switch to Maildir, which I'd like to do, but don't know how to with sendmail (with postfix, it's a piece of cake). Any advice on what my problem is? I'm all ears! regards, Patrick

[Dovecot] 1.0alpha2 released
by Timo Sirainen 12 Sep '05

12 Sep '05

Changes: - Some cache file corruption fixes (shouldn't be any left?) - Some index file fixes with mmap_disable=yes - Some mbox syncing fixes - Timezones in mbox From-lines were handled wrong - Added pop3_reuse_xuidl setting. Patch by Chris Wakelin - "stack frame changed" crashfix for FETCH BODYSTRUCTURE - Added %R (reverse string) and %H (hash string) variable modifiers. These can be useful if you want to automatically split users to multiple partitions (eg. %3RHu gives values 0..2 based on the given username). See doc/variables.txt for more information. The POP3 bug mentioned in ChangeLog doesn't actually exist, so don't be alarmed by it :)

[Dovecot] Do index files need removing when upgrading 1.0-stable to 1.0-alpha1 or later?

Hi Timo, Just a quick question: do index files still need removing when upgrading from 1.0-stable (as in the testXX series) or will Dovecot regenerate them automatically? I'm expecting to go with 1.0-stable on Tuesday for my 20,000 users (as that's what I've been testing), but if we see lots of index issues, I may want to upgrade to alpha1 (or later) fairly soon afterwards and it would be annoying to have do delete thousands of indexes!

[Dovecot] subscriptions or .subscriptions?

I may have found a problem with the documentation concerning the subscriptions file. On the Dovecot web site there is a document that outlines the conversion from UW IMAP to Dovecot. The document says Dovecot's folder list is stored in ".subscriptions" However, I have found that Dovecot's folder list is really "subscriptions" without the preceding dot. Did Dovecot version 1.0.alpha1 remove the dot from the subscriptions filename? .subscriptions does not seem to work at all. http://wiki.dovecot.org/moin.cgi/Migration#head-5dde807bf059dea93fc2303e202…

[Dovecot] Problem in dovecot 0.99 - login username case sensitive create fake maildirs
by Max CtRiX 11 Sep '05

11 Sep '05

Hello, I have noticed a weird behaviour in dovecot 0.99 which, I hope, is not replicated in 1.0-alpha. First I have to say that it works very well. So if I login with user foo(a)bar.com, the maildir is created. But when I log in with User FOO(a)BAR.COM, or FOO(a)BAR.com, then two other maildirs are created. Authentication is ok (I'm using mysql backend) but no mails are obviously found. Maybe a solutions would be adding some config item to turn lowercase the maildir path or authentication tokens (received from client) at login time. Or maybe I am missing something. Is there a solution for this problem out there ? Thanks, Massimo

[Dovecot] POP3 problem about multi users from one IP address concurrent
by Yi Xuan 11 Sep '05

11 Sep '05

Hi,all I have a POP3 problem about multi users from one IP address concurrent. [Issue description] The network architecture is as following. I have setup a mail server(sendmail/dovecot) in PlaceA with IP_A. And about 6 users are receving mail from the same IP_B( NATed public IP) in PlaceB. Their mails are many( about 1Mb/hour each) and ususally set fetch time as 10min/fetch. Then they complain that their mails often cannot be downloaded. [Reason investigation] I noticed that 1.when one of them fail to fetch mail. All TCP IP connection between IP_A and IP_B will be RST.which means that http/ssh/pop/smtp all not work for a while. And after about 10 minute, the http/ssh can work well. 2.I have asked them to backup and delete pop accounts and use webmail through imap provided by dovecot.And that seems work well but inefficient. I think this maybe because of multi users from one IP address concurrent, [Question] Would you pls provide some suggestion or solution about this issue? Is this a bug of dovecot or just a mis-configuration I don`t know? Thanks in advance for any advice. Best regards, Yi Xuan
