[Dovecot] RE: Locking problem
by Alex S Moore 20 Mar '04

20 Mar '04

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? I changed some timeout settings in dovecot.conf, but that did not help. Every time that I click this particular folder in my MUA, the screen locks up. Thanks, Alex

[Dovecot] Case insensitive user names
by andrew fresh 20 Mar '04

20 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?

[Dovecot] triggering multiple actions on pop-3 request
by Eric S. Johansson 17 Mar '04

17 Mar '04

I want to trigger fetchmail when a user makes a pop-3 request. The reason for this is so that the messages retrieved by fetchmail can be filtered via an anti spam service before depositing them into the inbox. The way I figure it, since I need to know who the user is and that they authenticated in order to make the correct fetchmail call, I need to spawn the fetchmail process somewhere between the authentication and the pop 3 process. since I'm currently unfamiliar with code at that level, could I get a suggestion as to where to start looking?. apologies if I haven't explained is clearly enough. I'm still just kind of exploring the idea myself to see if it's the right way to approach this problem (pop 3 anti spam Gateway). If it works out right, it may even end up as part of a firewall (IPCop) as a way of making anti spam trivially easy for the technically challenged. (I.e. put it in a box, said it up right, don't let them touch it) I know it is also somewhat off topic for the group but since I want to modify dovecot (the IMAP server that rescued me from UW), I figured I would give it a shot. thanks in advance, ---eric

[Dovecot] Corrupted Indexes and File Permissions
by Dominic Marks 16 Mar '04

16 Mar '04

Hello, I'm using Dovecot to provide an IMAP service to a small number of users and I'm seeing two recurring errors which look like they might be related. Environment: o FreeBSD 5.2.1 / Postfix 2.0.18 / Dovecot 0.99.10.4 o Maildir mailboxes Problem: On logging in all the folders under the users mailbox are empty. This has happened with both MS Outlook 2000 clients as well as Squirrelmail which uses c-client. When you look at the mail log it shows errors from Dovecot about index file corruption and file permissions (see attached sample section). I've checked the permissions on the maildir and it seems at the moment that the user has rw permssion on every file under cur, could this error be caused by an interaction between Postfix and Dovecot? Any comments / suggestions greatly appreciated, -- Dominic Marks

[Dovecot] index file corruption
by mat＠reynerie.org 16 Mar '04

16 Mar '04

Hi, I'm using Dovecot (dovecot-0.99.10p0) on OpenBSD-3.4 for few weeks now. When i connect to my IMAP account the connection is often closed by dovecot when i try to delete mails. I can see messages like this in log: Feb 29 18:47:00 po imap(mat(a)reynerie.org): Corrupted binary tree file /home/mat/Maildir//.INBOX/.imap.index.tree: used_file_size larger than real file size (1772 vs 1556) I tried to remove all index files, but the problem still occur. I also tried Maildir and Mbox, same problem (i can't remember if the log are similar with mbox, if needed i will test again). I have ktraced the imap process and try (succesfully) to reproduce this behaviour: I have re-send a lot of spam and delete few of them from mailbox until the problem occur. All logs/kdump/config are here: http://mat.reynerie.org/dovecot/ In the kdump file, the problem is visible at the end, Dovecot is compiled (via ports) with: env CFLAGS="-I/usr/local/include -L/usr/local/lib" CONFIGURE_ARGS="--with-ldap --with-ldap-includes=/usr/local/include --with-ldap-lib=/usr/local/lib" make Searching the mailing list archives, i have not found any solutions. -- mat

Re: [Dovecot] Mysql patch question
by Skye Poier 16 Mar '04

16 Mar '04

Last question of the day I promise :) If dovecot is configured to use the MySQL patch, ie: auth_userdb = mysql /path/to/dovecot-mysql.conf auth_passdb = mysql /path/to/dovecot-mysql.conf Its not possible to "chain" authentication methods is it? I mean, if its using MySQL it _cannot_ be configured to check passwd (via "pam *") first, and then check mysql, right? So, if I want to support real shell users (who are in /etc/passwd) I will have to have them in mysql along with the "virtual" users. ...... OK I lied, one more question! I love the feature that you can login with a username user@domain and the domain is automatically parsed out. Do these options have anything to do with the @domain part (referred to as a realm in auth.txt) or are they for something else completely? I'm not sure what SASL is that it refers to in the example .conf #auth_realms = #auth_default_realm = Thanks, Skye

[Dovecot] Help with dovecot+passwd+pam_mysql
by Skye Poier 16 Mar '04

16 Mar '04

Hi again, I'm on Freebsd 4.x and instead of using the mysql patch, it seems like it would be easier to just use "auth_passdb = pam *" with the pam_mysql drop-in. I'm not really a pam.conf writing expert though. Here's what it currently contains (works for /etc/passwd users) imap auth required pam_unix.so imap account required pam_unix.so try_first_pass imap session required pam_deny.so How would I set it up so that it first checks to see if the user is in /etc/passwd (as above) and then checks pam_mysql.so? Example from the pam_mysql readme: auth optional pam_mysql.so user=root passwd=password account required pam_mysql.so user=root passwd=password Is anyone else using this setup? Any disadvantages? Thanks, Skye

[Dovecot] dovecot & vpopmail
by Dirk Jäckel 12 Mar '04

12 Mar '04

Hi! Authentication works, but default_mail_env = maildir:/usr/local/vpopmail/domains/%d/%n/Maildir/ is translated by the "imap"-process to /usr/local/vpopmail/domains//testerhorst/Maildir/ although I succesfully log in as testerhorst(a)elektropost.org. Is there a manual how to use dovecot with vpopmail? We have here: FreeBSD 4.9-STABLE, vpopmail-5.4.0 and dovecot-0.99.10.4_2. Thank you for your help! Regards, Dirk Jaeckel

[Dovecot] imap internaldate
by Payton 10 Mar '04

10 Mar '04

I think I found a bug in dovecot which I'm not sure where to fix. (I may even have found a reference to it in an archived list message from Jul 2003.) Here is the situation: dovecot (dovecot-0.99.10.4) running with an imap server on an mbox system is queried by a local client program, like Mail.app, and is told the "Received" date of the message (presumably sent through INTERNALDATE), however, that date is being passed on in GMT (-0000) instead of the server or client's local time zone (EST -0500, in this case). Maybe it's assumed that the local client will convert this time to the local zone, but no clients I know actually do that. Anyone know how/where to fix this? Thanks! - Payton - payton(a)repligen.com

[Dovecot] Problems with Mozilla
by Tres! 09 Mar '04

09 Mar '04

Hello, I've some problems with Dovecot and Mozilla. First of all i have to mention, that Dovecot is installed on SuSE Linux 8.2 and uses up to 20 Win32 Mozilla clients. If you need further information, please let me know. My problem is, that I got one or two times a week a login failure from Mozilla, and the clients can't connect anymore. The error message from Mozilla after a long time "checking server capabilities" is "server is not an imap4 server". I haven't found something usable in the logs except for a login timeout of the clients who want to connect. If i kill the imap and imap-login tasks and restart redove, everything works well for some days. Is there anyone who knows something about my problem? regards Tres!

[Dovecot] RE: imap segv trying to list inbox
by Sam Powers 09 Mar '04

09 Mar '04

(This is releveant information to the one that Alex Moore just posted, but I'm not subscribed yet so I can't properly reply to that thread. Sorry for creating a new one.) I've got a crash in dovecot-imap when trying to list the inbox on a nonexistant directory. I'm not sure how it should be handled, but basically it's only happening when the directory in imap's MAIL environment doesn't exist. This is a problem for me because I'm trying to have dovecot create all the necessary directories in the specified environment, as I don't know if the user will pop/imap or recieve an email first, and the dir needs to either be already ready, or created upon reciept. I've already got postfix to create a ~/Maildir when a new mail comes in, but for my migration plan to work, I need dovecot to create this directory instead of segfaulting. ;) dante:/usr/lib/dovecot# MAIL=maildir:/tmp/nonexistant gdb ./imap (gdb) run Starting program: /usr/lib/dovecot/imap (no debugging symbols found)...(no debugging symbols found)... * PREAUTH [CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED] Logged in as root 1 list "" inbox (no debugging symbols found)...

Now, if I leave default_mail_env blank, and let dovecot's autodetection do the work, it seems to create a maildir in ~/mail. This works just fine, except it's the wrong directory. Otherwise, dovecot rocks, and in another, less automatic setup, I've been using it for the better part of a year with nothing but happy results, and appreciate your work. (Irssi too :) -Sam

[Dovecot] RE: imap process abends

I am trying to setup dovecot imap on a test Solaris 8 box. I have dovecot POP3S running fine on another box, but I want to switch to IMAP. I see a successful login with a message like: Mar 8 13:22:47 sws601.mcsun.local imap-login: [ID 457029 mail.info] Login: sunuser1 [192.168.1.17] Then the Mozilla Mail client gets a message that the server disconnected. It appears to be from a segfault on the imap process.

[Dovecot] Mails manipulation and indices
by Giacomo Cariello 06 Mar '04

06 Mar '04

I've recently manipulated the contents of my maildir, changing the content of some mail files (mime handling and such...). This broke dovecot since it expected different filesizes while reading contents of files that were previously indexed. Therefore dovecot returned some assert like this: imap(jwk(a)bug.it): file istream.c: line 163 (i_stream_seek): assertion failed: (v_offset <= stream->v_size) Obviously, the solution was to remove indices and have dovecot recreate them. I suppose it would be more "polite" to have this kind of routines (i_stream_seek etc) handle this case by requesting indices recreation for indices that are no longer "real", instead of just dropping connection with some "internal error" message.

[Dovecot] OS X 10.3, SSL, client connection hangs?
by Chad Bergeron 05 Mar '04

Ok, I've just installed Dovecot, and got it set up in xinetd for ssl and plain/pam. Everything looks good, I even got to the point where my client (mail.app) asked if I wanted to accept the new certificate I'd made. All good. But then the imap connection seems to hang right after negotiating. Nothing shows up in my logs except a disconnect, usually for inactivity. Has anyone else managed to set Dovecot up on 10.3, and has anyone seen this issue, or ones like it? Trying to figure out where to go from here... -Chad Bergeron

[Dovecot] imap MUA received
by Payton 04 Mar '04

04 Mar '04

Does anyone know where MUAs like Outlook, Entourage, and Mail.app get their 'Received' or 'Date Received' information from? It certainly doesn't appear to correspond with the mail headers, at least in my case, so I'm guessing it's possibly getting that data from the IMAP server? My mail clients (MUAs) show the 'Receieved' time as 5 hours off. I have qmail running as my MTA, and since it stamps emails' "Received" header with time in GMT (-0000) and I'm in EST (-0500) I thought that was the problem. However, I patched qmail to set the headers in -0500 instead, which worked as far as I can tell, but the MUAs *still* report the time incorrectly! (Time on both the client and the server are correct as well.) Here is my setup: dovecot running pop/imap mbox files (yes, i know this is bad) qmail as my MTA (used to list time as GMT in headers, but I patched it and now the headers list time in the local zone instead) -- ;; Payton Swick ;; ;; Repligen Corporation ;; ;; IT Systems Administrator ;; ;; payton(a)repligen.com ;;
