Rick thanks for the message, -I have not done any changes to the default nsswitch.conf. I checked and the entry hosts: files dns is there -127.0.0.1 localhost entry is in the /etc/hosts file. -ifconfig shows that the interface is up and I can successfully ping it by name ( ping localhost ).

In the Wiki, section 2, "Virtual user support with OpenLDAP", does the example apply to non Sendmail? If that's the case, can someone post a quick guide about setup virtual user with Sendmail. I use OpenBSD-3.4, BTW. TIA, Zoong

Hi , I recently installed Fedora Core 1. Installed postfix on it and that is running fine.

[Dovecot] adding new user to dovecot
by Kartik Vaidyanathan 18 Apr '04

Hi, Your mail was very insightful. You have stated in you mail as follows .. "But I think they create virtual users in database systems for email, I can't imagine all of the users they have are in one passwd file on one tiny machine." a. What do you mean by virtual users. b. How does one link them to a mailbox. Very frankly i am confused... 1.Well lets say i have a user who wants to create a new group say GROUP1.Lets say i have users who want to create GROUP1(a)pigeonhole.com or GROUP2(a)pigeonhole.com .This group name will be entered in my JSP page, now what do i have to do to create the group. 2.How do i see to that anyone who sends a mail to GROUP2@pigeonhole receives it in it mailbox( Firstly does the group have a mails box in the groups name).Will one create a account(mailbox) for the group or how is it done. 3.Lastly I actually want to create a mailing List manager. Please advice on how to go about it.

by Kartik Vaidyanathan 18 Apr '04

Hi, Thanks a lot for the mails.Well one major doubt that was prevailing was that do i need to create a system account for each person in order to send/receive mails, and from both(Sven Kirmess & Johannes Berg ) your mails i gather it is a must. But Is there a workaround to this? I have actually configured dovecot because i required a mail server in order to build a mailing list manager.A mail list manager is something in the likes of yahoogroups, where each group in my case must have a mailbox. 1. I am using Debian OS. The software that i am creating , which is going developed in JSP, will take a new users name and password and create a account for him by executing a shell script in my linux machine.I assume yahoo also does something similar to this to create new mail boxes for any new user.Please correct me if i am wrong. In fact this very mail that i have received from you is because i have subscribed to the dovecott mailing list. How do you think dovecott has been able to accomplish this. Is it not because that dovecott has a mailbox in the group name "dovecott" in some system, that internally does the sending of mails to all those in the groups refering to some database. 2.Will the mail server support me in anyway by giving me some functionality to add users, thereby creating maildir's (imap) for the users. 3.Dont I need to know the admin login and passwd, to create users? 3.Lastly i know this is not that prevalent a question -> I was told mail man does a similar job as to what my software will do.Do you know how mailman works (or even yahoogroups)?. Please enlighten me on the above issues. Thanks a lot for you time. Regards Kartik

[Dovecot] adding new user to dovecot
by Kartik Vaidyanathan 15 Apr '04

15 Apr '04

Hi, This is from your documentation Creating new users ------------------ Dovecot is interested in only one thing - being able to find the user's mail directory. With maildir you need to do mkdir ~user/Maildir, with mbox mkdir ~user/mail. what does ~ refer to. Pardon my ignorance in unix, i am relatively new to unix. Does not ~ refer to the user account in which you have logged in. So does that mean that maildir folder exist for only user accounts that already exist.My intention for asking the above is that i have a java program running, that will take a new users name and password, so with that can i create a mailbox for that person , or does the admin have to create an user account for that person , so that his maildir folder can be created. Please clarify my understanding of how it workds.. Thanks

Sorry if this question has been asked before I looked through some of the archives before posting this. I am considering using dovecot on a small 35 user environment (only around 6 gigs of email) that will be primarly be used with squirrelmail for the MUA. I have been using dovecot for a few weeks now and really like it. It is a big improvement over uw-imap thats for sure. I was wondering how many people in this mailing list are using dovecot for a production email server, and why you chose to use dovecot over cyrus or courier. Or maybe someone feels that dovecot isnt ready for this type of thing just yet. I am all ears so please feel free. Thanks -- Avery -- Avery Day

[Dovecot] Dovecot startup at boottime fails
by Bavo De Ridder 08 Apr '04

Hi, I am running dovecot 0.99.10.4 on SuSE 9. I installed it using apt-get from the gwdg repository. The dovecot service is configured to start at boottime in run level 3 and 5. However, it dies immediately with this error (/var/log/mail.err): dovecot: Login process died too early - shutting down Starting the service afterwords from a prompt as root with the command: /etc/init.d/dovecot start works without a glitch. Attached you can find my dovecot.conf and the startup script /etc/init.d/dovecot. I hope someone could shed some light on this issue.

[Dovecot] dovecot vs. cyrus IMAP?
by Jim Norton 08 Apr '04

08 Apr '04

Hello all, I just learned about dovecot. I am currently using Cyrus IMAP/POP3 with Postfix on a Linux system. The one thing I don't like about Cyrus IMAP is that it doesn't support mail users who have accounts on the system. It uses it's own mailbox format and the users can't be regular system users. It would be nice to have an IMAP/POP3 server that can handle mail for users in /etc/passwd as well as the cyrus 'virtual' user type. Does dovecot only provide access to mail for users in /etc/passwd? Or can one setup email accounts for people that don't have accounts on the system ( in /etc/passwd )? Thanks, -- Jim Norton - http://www.jimnorton.org Recursion; n. see 'Recursion'

[Dovecot] username and password not from /etc/passwd
by Zoong Pham 08 Apr '04

08 Apr '04

Can dovecot use usernames and passwords not from /etc/passwd and be able to read mails of an user whose username and password are in /etc/passwd ? For example: - Joe Bloke has a local Unix account joe on Unix server mail.example.com - Sendmail on mail.example.com accepts mails for joe(a)example.com and put them in /var/mail/joe - can dovecot use other username/password file or database or directory rather than /etc/passwd to authenticate Joe and let him (once logs in successfully) reading mails in /var/mail/joe ? Ideally, the usernames and passwords that dovecot uses are different with the ones in /etc/passwd. Say, username is joe.bloke(a)example.com That way, Joe doesn't need to know the username and password on the Unix server at all. In summary, I want to have IMAP usernames and passwords totally different from the local Unix usernames and passwords. And users use only IMAP usernames and passwords to read their mails. I use OpenBSD-3.4, Sendmail 8.12.9, dovecot-0.99.10p0 (pre-compiled packaged from OpenBSD). Thanks, Zoong Pham

The correct behavior should be to only download the new message. from doing a search on dovecot and uidl, it seems that dovecot supports these functions, which is the standard way for a pop3 server to announce unique checksums of messages.

Hey- Just wanna say that I'm really happy with Dovecot, it has worked really well for my small operation. I do have a couple problems I'd just like to bring to everyone's attention for future bugfixes and if there is a solution available. I'm using dovecot-0.99.10-6 with a clean fedora core 1 install. I'm using primarily IMAP with OpenSSL, however a few people use POP3 (over SSL) with outlook 2002 clients. The problem is that with each send and receive another copy of all messages in their Inboxes are downloaded. I have tried closing outlook restarting it etc. nothing seems to help unless I tell outlook to remove all messages from the server then outlook responds with "messages that outlook was attempting to download are no longer on the server." And problem solved. Not a huge deal but others with similar setups may be experiencing the same problems. I have postfix for my MTA, every account uses Maildir. Attached is my dovecot.conf.

[Dovecot] dovecot with sendmail
by electron electron 06 Apr '04

06 Apr '04

Hello, Here is an issue. I am trying to make dovecot work with sendmail If I use the default conf file (default_mail_env = ) then the inbox is the file /var/mail/user and a mail folder is created in /home/user directory where it stores all additional imap folders. The problem with this is that I cant have subfolders. If I edit dovecot.conf file and enter default_mail_env = maildir:/var/mail/%1u/%u/Maildir then I can create subfolders, but new emails are not stored in INBOX, but the stay in /var/mail/user. In order to overcome this issue I used procmail .procmailrc: ---------- { :0 Maildir/ } ---------- So now all emails are stored in Maildir format and again with the default dovecot.conf file it works fine. I was wondering if there is an alternative way to do this, without using procmail..just editing the dovecot.conf file.

I am getting the following in the logs: Apr 5 10:21:25 ziegchen dovecot: Dovecot starting up Apr 5 10:21:26 ziegchen dovecot: Auth process died too early - shutting down Apr 5 10:21:26 ziegchen dovecot: child 30091 (auth) returned error 127 Apr 5 10:21:26 ziegchen imap-login: fd_send(-1) failed: Broken pipe This is with SSL on or off, I have tried building the source many different ways, but it behaves the same every time. I even copied the config from a working installation and tried it with that, but to no avail. Any insight would be appreciated. -- Brian T Glenn delink.net Internet Services

[Dovecot] dovecot not reconnecting to ldap after ldap restart
by Jared 05 Apr '04

05 Apr '04

I upgraded dovecot two weeks ago from 0.99.10-0.rc2 to 0.99.10.4-1woody1 (both from the woody backport packages from braincells.com) Dovecot is using LDAP on a separate machine for authentication. (through stunnel if it matters) At 4:00 am, the LDAP server stops, dumps the ldap database, and then starts back up. Because the LDAP server is stopped, anyone who tries to authenticate during the few seconds will be denied. This isn't a big deal since it's 4:00 am. However, twice in the past two weeks, it appears that if dovecot can't connect to the LDAP server, it loses the ability until dovecot is restarted. It's only happened since I upgraded, and it's only happened twice, presumably when someone was trying to check their mail at the precise moment the LDAP server is down. I get the following entry in mail.err: Mar 30 04:00:18 akbar dovecot-auth: LDAP: ldap_result() failed: Can't contact LDAP server Mar 30 04:00:19 akbar dovecot-auth: LDAP: Can't connect to server: localhost Mar 30 04:00:50 akbar last message repeated 36 times . . . The two times it has happened, ldap is responding properly (all other services we provide which use LDAP still work), stunnel on the dovecot machine is still running, and dovecot is still running, accepting IMAP and POP connections, but failing at the authentication phase. Is there some change or bug in dovecot which would make this happen? Or is there a problem with my set up? Thanks in advance for any ideas. -jared

[Dovecot] passwd-file maintenance by users, other options
by Mike Brown 04 Apr '04

04 Apr '04

I am using Dovecot to provide IMAP and IMAP+SSL service for my users, but am still using QPopper for POP3 service, wrapped with stunnel for POP3+SSL. I am hesitant to get rid of QPopper because it supports APOP, which encrypts authentication data (both where it is stored, and when it is transmitted), and because APOP passwords can be managed by the users themselves, via the popauth tool that they can run from their shell accounts. I'd like very much to use Dovecot for POP3, but would need to have it be comparable to APOP, where authentication does not involve having user passwords going across the wire in the clear, and especially I need for users to be able to maintain their passwords themselves, preferably with their status as a current user of the system being established without my intervention; I don't want to have to manually keep things in sync with /etc/passwd. Furthermore, it needs to have no conflicts with popular email clients including Mozilla, Outlook, Outlook Express, and Eudora, so unusual authentication mechanisms are not really an option. I've RTFM at http://www.dovecot.org/doc/auth.txt but I don't know how to establish a separate passwd file that would satisfy the requirement that users be able to maintain their passwords themselves. And PAM is a complete mystery to me. So what do you all do? Is there a tutorial somewhere that would help? Thanks, M.

[Dovecot] Bug fix - message/rfc822 attachments
by Rick Jones 03 Apr '04

03 Apr '04

Greetings I've attached a patch that fixes a bug in Dovecot relating to rfc822 attachments. This problem shows up in Mulberry (which hammers the IMAP protocol more than most!). The problem is that FETCH BODY[n], where "n" is the number for the message/rfc822 part, returns the wrong information. It returns the message without the headers, whereas it should return the entire rfc822 attachment. FETCH BODY[n.MIME] doesn't appear to return the MIME headers for the part either. This happens because the find_part() function always steps down into the child when the type of the part is RFC822. It should only do this if the request is for a sub-part, or for HEADER. Otherwise it should stay at the current level. I have to say the IMAP protocol is a bit perverse in the way implicit nesting of rfc822 messages is handled, which is why this looks somewhat hacky. I don't see a nicer way though. The effect in Mulberry is that certain operations on rfc822 attachments don't work properly, in particular extracting the attachment into a separate message. It also affects message-digest format messages, which will completely lock up Mulberry if one is even present in a mailbox. (It may be that Dovecot itself hangs, I don't know. Once I found that the patch fixed both problems I didn't look any further :) Mulberry doesn't exhibit these problems with other IMAP servers. The attached patch is for the source code of 0.99.10.04. I've looked at the "latest" source, and there is no change in these lines of code, so I guess the bug is still there. -- Best regards Rick Jones

[Dovecot] SSL error and PostgreSQL
by eLgino 02 Apr '04

02 Apr '04

Hello there, Anyone have a Howto for me how i can configure dovecot to work with a PostgreSQL Database? (the docs are small), i want to use it with Exim4 and i have a error with SSL "imap-login: Can't load private key file /var/dovecot/ssl/private/imapd.pem: error:0906D06C:PEM routine:PEM_read_bio:no start line" i make my cert with this command (i don't like the included script :)) openssl req -nodes -new -x509 -keyout imapd.pem -out imapd.pem -days 3650 or openssl req -nodes -new -x509 -out imapd.pem -days 3650 the pem is file is in the right directory and have "a chmod 700,777 or 600" no one of the this will work. sorry for my poor english and thanks in advance

[Dovecot] Failed to create storage with data
by Tim Middleton 01 Apr '04

01 Apr '04

Switched from UW-IMAP to dovecot a little while ago. Worked through the namespace hell with current users. But now I've hit another problem I can't seem to figure out. Some webmail (squirrelmail) users noticed that when they tried to login they would jus get this error: ERROR: ERROR : Connection dropped by imap-server. Query: CAPABILITY I discovered in the mail logs the real error was like this: Apr 1 04:28:38 smaug imap(mcfletch): Invalid mbox file /var/mail/mcfletch: No such file or directory Apr 1 04:28:38 smaug imap(mcfletch): Failed to create storage with data: mbox:/var/mail/mcfletch And the error seems to be quite accurate. These are new logins seeing this error, which do not yet have an mbox file. So the question is, why is dovecot not able to deal with this situation? Searching google i saw the suggestoin to one preson that it was actually the ~/mail directory unable to be created, but this is not the case in my test above, as ~/mail already existed for that account. Directory permissions seem okay. /usr/mail is drwxrwxrwt (note: /var/mail is a symlink to /usr/mail on this system). The dovecot setup is fairly default. Platform is FreeBSD 4.9. Authentication is done via system password file. There's no problem accessing/modifying existing mailboxes. I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions. -- Tim Middleton | Cain Gang Ltd | "Are the gods not just?"

[Dovecot] Mulberry problem
by Rick Jones 01 Apr '04

01 Apr '04

I've been chasing a problem with Mulberry which now actually seems to be a Dovecot server bug. The problem manifests itself when manipulating embedded rfc822 messages, and the analysis comes down to the fact that a FETCH BODY[2] command returns the same thing as FETCH BODY[2.1]. Both return just the text of the embedded message, whereas FETCH BODY[2] should return everything including the headers (this is what Cyrus Daboo came up with after looking at the Mulberry log). I'm not sure exactly what version of Dovecot I'm running, it's what comes with SME Server 6.0. Has this by any chance been fixed? I have another Mulberry problem which might be related, but I'll save that for another post :) -- Regards Rick Jones

[Dovecot] Rogue child imap processes when using Mac imap clients
by darren david 31 Mar '04

31 Mar '04

hi all- I am currently running dovecot 0.99.10p2 on OpenBSD-3.4-snapshot. It has been very stable, but I have recently noticed that I am having problems when checking IMAP-SSL mail with Mac OS X clients. There are not problems using Mozilla or Outlook on Windows, but Mac clients (Thunderbird, Mozilla, Mail.app) all exhibit the same behavior - they can check and send mail, but I end up with a single, rogue child imap process on the server that pins the cpu that i have to 'kill -9' to clear out. Is this a Mac problem or a Dovecot problem? I'm not even sure what to look for in the logs... Thanks, Darren David

[Dovecot] New indexing code
by Timo Sirainen 31 Mar '04

31 Mar '04

Sorry about the lack of replies to questions in this list. Work on the new indexing code has taken way too long, but it's finally beginning to be get near usable state. After it's fully working, I'll start being more active here again. If you're interested (as a developer, normal users shouldn't even try playing with it yet), you can checkout "newdove" module from Dovecot CVS. Many things are still broken, but basic maildir support is almost working with the exception of expunges (which probably break badly) and custom flags (not implemented). And the maildir syncing code isn't optimized yet. Don't try it with any of your real maildirs, it might lose your mails. Some of the new great things in it: - Mailbox API which is a lot more easier to use than before, allowing a lot of things that previously were difficult to implement - Less IMAP-specific than before - Should work extremely well with shared mailboxes with tons of users I'm hoping to get a usable alpha release out of it within few weeks.

[Dovecot] UW-IMAP -> Dovecot : patch to remove nasty "internal messages" from UW-IMAP ?

Hello there, We want to move from UW-IMAP to Dovecot (mbox format), works like a charm, but UW-IMAP has that bloody habbit to make a stupid message in all his mailbox files : From MAILER-DAEMON Thu Apr 19 10:30:01 2001 Date: 19 Apr 2001 10:30:01 +0200 From: Mail System Internal Data <MAILER-DAEMON(a)mailhub2-vil.isdnet.net> Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA Message-ID: <987669001(a)mailhub2-vil.isdnet.net> X-IMAP: 0987630138 0000000001 Status: RO This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Is there any patch / trick / whatever to avoid that such "stupid" message to be not served by dovecot ? Thanks, /Xavier

I deleted the index folder to fix a lock problem described on my previous post. I still cannot access the folder. Now, I have a file in the maildir folder named dovecot-uidlist.lock that must be corrupt. How do I fix this? I can remove this particular maildir folder and there is no great loss. But I want to know how to fix it, in case this problem occurs on an important folder. Thanks, Alex

Running dovecot on Solaris 8 sparc with SylpheedClaws as the MUA. I tried moving to many messages from a folder to my maildir folder, which is a local directory on the dovecot server. Now, I cannot open the folder due to this message: 'Mar 20 10:26:15 sws601.mcsun.local imap(amoore): [ID 702911 mail.error] Timeout while waiting for release of shared fcntl() lock for index file /var/indexes//amoore/.Spam.Spam Archive/.imap.index' How do I get the lock released?

[Dovecot] Case insensitive user names
by andrew fresh 19 Mar '04

19 Mar '04

I am trying to set up the Dovecot pop3 server for some virtual hosting I am doing and it is going well, I am generating a passwd file that points dovecot to the virtual users mailspool. The only thing that I don't have working is that my current pop3 server (NTMail) has case insensitve usernames. Dovecot doesn't. I was hoping there was just an option to turn on, but I didn't see one, and unfortunately I don't know enough C to change to lc($submitted_user) eq lc($database_user) like I would in perl :-) I do have control over generating the passwd file, and it is currently generating the users to lowecase in the file, so just lc($submitted_user) eq $database_user would work well enough. Unfortunately I don't know enough C to do that, so I thought I would ask if anyone has done this. So, does anyone have any ideas on how to do this?

[Dovecot] chdir() on NFS
by Christian Andersen 19 Mar '04

19 Mar '04

Hi, I'm having problems accessing home directories though NFS. This setup uses LDAP and Kerberos. Users defined on the local host work fine. This is what dovecot writes in the logs while trying to log in as the user johndoe: ---- Mar 19 14:10:54 jack dovecot-auth: nss_ldap: reconnecting to LDAP server... Mar 19 14:10:54 jack dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) Mar 19 14:10:54 jack imap-login: Login: johndoe [10.0.0.30] Mar 19 14:10:54 jack dovecot: chdir(/home/johndoe) failed: Permission denied Mar 19 14:10:54 jack dovecot: child 3525 (imap) returned error 89 ---- The authentication is OK, but dovecot fails to get access to the home directory. What username does dovecot try to chdir() as? If I 'su' from to that user I have access to /home/johndoe, and a quick test with Courier IMAP worked fine. Postfix has no problem delivering mail in the users maildir using procmail. Some relevant config options: default_mail_env = maildir:~/mail:INDEX=/var/indexes/%n auth_userdb = passwd auth_passdb = pam auth_user = root -- Christian Andersen <http://phuzz.org>

Sorry for the slow reply, it's taken me a few days to get back to this and observe the problem again. I've placed a tarball of the output of "strace -ff -o dovecot dovecot" here: http://rimu.tiddly-pom.com/dovecot-strace.tar.gz To my (admittedly untrained) eye, it's looking for and not finding /etc/ld.so.nohwcap, and then repeatedly not finding /var/run/dovecot/ssl-parameters.dat. At that point there is a /var/run/dovecot/ssl-parameters.dat.tmp - is that where the SSL stuff is being generated? Is it just that Dovecot is stalled until the ssl-parameters.dat file appears?

[Dovecot] duplicate mails
by Neal D. Becker 18 Mar '04

18 Mar '04

I run kmail and use it to automatically sort my mails to various imap folders (using kmail's disconnected imap). If I fire up a second instance of kmail (e.g., @work + @home) then both will do this, and I wind up with 2 copies of each mail. Can dovecot be taught to discard duplicate mail ids, or maybe some other mechanism to avoid this problem?
