[Dovecot] avoiding getting maildir cur/ folder contents?
by Johannes Berg 19 Jul '07

19 Jul '07

Hi, On my server with many mails in one folder and slow IO, getting the mail listing in the cur/ folder is becoming a serious bottleneck. Dovecot is the only thing accessing the mail folders, so would there be any way to avoid getting a listing all the time? johannes

[Dovecot] Small problem with src/lib/mountpoint.c [now with patch attached!]
by Mike Brudenell 19 Jul '07

19 Jul '07

Greetings - [SIGH: I hit the "Send" button instead of "Attach". Here's Take 2...] Whilst playing with getting quotas from NFS-mounted filestores I've just discovered a slight problem with src/lib/mountpoint.c I had things working on a Solaris 10 test machine which had the mailstore mounted 'normally' using an entry in /etc/vfstab. However when I changed to use the automounter for the mailstore obtaining the quota broke. The problem lies with mountpoint_get(). On a 'normally' mounted filestore this obtains the device_path of the remote filestore in the form remoteservername.some.domain:/remote/path However when the mailstore was automounted I was instead getting back auto_direct which is the name of the automounter map we're using. The /etc/mnttab file has TWO entries for the auto-mounted filestore, like this: auto_direct /mailstore/messages/p autofs direct,ignore,dev=4740014 1184648400 crypt2.york.ac.uk:/vol/vol9/p /mailstore/messages/p nfs proto=tcp,xattr,dev=4700386 1184668792 Although there are two entries they have different device numbers. The mountpoint_get() function attempts to guard against this by checking the device number obtained matches that of the path being located. However for some reason I don't understand when getmntent() returns the FIRST of the above two entries it supplies the device number of the SECOND. Thus the device numbers match in the mountpoint_get() test and it thinks it has found the correct entry. This leads to the device_path being set to the map name -- auto_direct -- instead of the host:/path My fix is to add an additional fstype for the test to ignore: "autofs". The loop skips over any such mounts (along with the existing tests for "swap" and "ignore"). I'm attaching my minimal patch in case it's of help to anyone else. (Timo: would it be possible to get this added into the distribution code if you agree it's right?)

[Dovecot] Integrating dovecot 1.01 into CentOS-3.8 systemw with chroot passwd dirs?
by Gary Goldberg 19 Jul '07

19 Jul '07

Hello. I'm administrating a CentOS 3.8 linux system (RHEL3) and I just replaced the imap-2002d-12 package that came with the system, with a dovecot 1.01 package I obtained through the dovecot home page. The problem I have, is that many of my POP3 users have jailed user accounts set up through wu-ftpd, where the dir field is of the form /home/group/./pop/user, and wu-ftpd chroots them from /home/group but then places them into their home directories, in this case /home/group/pop/user. dovecot can't seem to locate their mail directory. Can anyone offer any advice on this situation? Please respond to my email address <og at digimark.net> if you could. --- Here are some relevant stats: example user: lda01 home directory (in /etc/passwd: /home/lda/./pop/lda01 mail folder directory: /home/lda/pop/lda01/mail INBOX: /home/mail/lda01 (/var/mail, /var/spool/mail symlinked to /home/mail.) dovecot 1.01 output of dovecot -n: #1.0.1: /etc/dovecot.conf base_dir: /var/run/dovecot log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s ssl_disable: yes ssl_cert_file: /usr/share/ssl/certs/dovecot.pem ssl_key_file: /usr/share/ssl/certs/dovecot.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: mail.digimark.net ready. valid_chroot_dirs: /var/mail:/var/spool/mail:/home/mail:/home mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/home/mail/%u mail_debug: yes mail_full_filesystem_access: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu auth default: passdb: driver: pam args: blocking=yes dovecot userdb: driver: passwd attempt to login using a Squirrelmail (webmail) client gave these entries in the dovecot.log error log: dovecot: Jul 12 16:22:50 Info: imap-login: Login: user=<lda01>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Jul 12 16:22:50 Info: IMAP(lda01): Effective uid=10572, gid=510, home=/pop/lda01 dovecot: Jul 12 16:22:50 Info: IMAP(lda01): mbox: data=/pop/lda01/mail:INBOX=/home/mail/lda01 dovecot: Jul 12 16:22:50 Info: IMAP(lda01): mbox: root=/pop/lda01/mail, index=/pop/lda01/mail, inbox=/home/mail/lda01 dovecot: Jul 12 16:23:04 Error: IMAP(lda01): open(/home/mail/lda01, O_CREAT) failed: No such file or directory dovecot: Jul 12 16:23:04 Error: IMAP(lda01): access() failed with mbox file /home/mail/lda01: No such file or directory dovecot: Jul 12 16:23:04 Error: IMAP(lda01): stat() failed with mbox file /home/mail/lda01: No such file or directory dovecot: Jul 12 16:23:58 Info: IMAP(lda01): Disconnected: Logged out -- -- "Outside of a dog, a book is a man's best friend. -- Inside of a dog, it is too dark to read." -- Groucho Marx.

[Dovecot] production switchover questions
by Stewart Dean 19 Jul '07

19 Jul '07

So far so good...other than a my-bad fubar with the permission on the index directory that kept DC from creating index dirs for the entering-for-the-first-time users, quickly noticed (thanks to the excellent logging) and corrected. Some questions 1) the max_mail_processes parm in dovecot.conf...is that *all* processes owned by dovecot? 2) I thought there was a parm to limit how many processes each user can have, but can't seem to find it. Is there any way to control that? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] deleting maildir files
by Tom Bombadil 18 Jul '07

18 Jul '07

Greetings all... Can we delete maildir files directly from the file system? Basically, we use dovecot to train spam, and we want to delete messages that are older than 30 days, using a simple "find /maildirs -cname +30 -name *imap-server* -exec rm {} \;" I have seen a post a while ago saying that dovecot can rebuild the indexes, but I don't remember if it's when the index is deleted or when the maildir files are deleted. And if we cannot delete files with the 'rm' command, whats the best/proper way to delete these older files. Thanks

[Dovecot] A little OT but hopefully still related enough... Maildir Delivered mail naming problems.
by Jesse C. Smillie 18 Jul '07

18 Jul '07

Normally I wouldn't post off topic to a mailing list, but I have posted every where else I can think of and haven't had any success yet working this out. I know there has to be a few people here with extensive knowledge of how mail works and maybe just a tip in the right direction would help me out at this point. I have migrated from mbox format to Maildir format in the last week. I used the utility mb2md.pl to convert all of our existing emails from one system to the next. I then modified my /etc/procmailrc file by putting this at the top: MAILDIR=$HOME/Maildir DEFAULT=$MAILDIR/ This way procmail is forced to deliver to the new format as well. For the most part all of this is working perfectly. Procmail is delivering emails to their new proper folder and even extended rules in users own ~/.procmailrc are working well once the folder path was changed from $MAILDIR/whatever to $MAILDIR/.whatever/. Works great. I am using Dovecot 1.0.1 to deliver our email through the IMAP protocol and with the clients we support (Thunderbird and Outlook) things are working very well for us. So now to my problem. We also use Usermin for our users to access their email when they don't have a supported client available to them. When users look at their email with Usermin their emails are out of order regardless of weather I have Usermin's "Read Mail" module using IMAP to get mail or have it read the users Maildir directly. Sorts are just all jacked up. Sometimes if users then click the "Date" button to sort by date it snaps to; sometimes it don't. I currently have multiple posts on the Webmin/Usermin mailing list about this problem and it really seems to point back to the naming scheme of our emails now. All emails which were converted have the classic maildir format. UnixTime.PID.Server... 1183737827.002379.mbox:2,RS 1183737827.002388.mbox:2,RS 1183737827.002392.mbox:2,RSa 1183737827.002394.mbox:2,RS However, all the email that is delivered after the fact is different. They all look like this: _oTH.XqwlGB.gator:2,RS _p2F.qjVlGB.gator:2,RS _qQF.2mpjGB.gator:2,Sa _sK.8mTlGB.gator:2,RSa _uOG.gCtjGB.gator:2,RS _uxG.a6lkGB.gator:2,RS _vnF.n-2lGB.gator:2, _x9H.llckGB.gator:2, _z3G.k8klGB.gator:2,S _z5G.kAilGB.gator:2,RS I have been searching the net for a few hours and reading various documentation here and there and I haven't been able to find anything that tells me why my mail is being named this way or how to fix it. I can say that my test box which also runs 10.2 slamd also delivers this exact same way.... For the most part I'm being told that the reason why Usermin's sort is all screwed up (order wise) in IMAP mode is that messages are displayed in the order that the IMAP server reports them. Like wise in Maildir mode the order which they are read. I can understand why this naming stuff throws everything off at this point. What I don't understand is why its doing this. I mean I'm pretty sure there is nothing here out of the ordinary as far as my config. I have searched all over the net the last few days and haven't been able to find anything useful. So in wrap up sorry for being a little OT and thanks a head of time for any info or light anyone can share here. -Jesse Smillie

[Dovecot] some mail reappears or marked as read again
by Herbert Gasiorowski 17 Jul '07

17 Jul '07

Sometimes a mail - already read or moved into another folder - appears again in the INBOX. I was not quite sure about this but today is once close the mail client (thunderbird 2.0.0.4 on fedora 7) and the only mail in the inbox was mark as unread. I think it happens in other mailboxes too. But it might be a client problem as I changed to dovecot and thunderbird 2 (from 1.5) nearly at the same time - but i think it happens before with thunderbird 1.5 too). In the logs there is nothing but some logins/logout.

[Dovecot] Problem with Dovecot SASL in Postfix

Ok lets try this again... I'm trying to configure my postfix server to use Dovecot as an SASL server and running into some problems.

[Dovecot] Getting quotas from an NFS-mounted filestore
by Mike Brudenell 16 Jul '07

16 Jul '07

Greetings - I was just wondering what the state of play was with regard to reading filestore-based quotas when the mailstore is NFS-mounted? Timo mentioned a little while ago that he'd be including it: http://www.dovecot.org/list/dovecot/2007-May/022594.html However it isn't in 1.0.1 and isn't mentioned in the release notes for 1.0.2. Is it going to be a 1.1 feature or will it appear before then? I'm asking because although I can't get the rquota-rquotad patch to build on Solaris I have found some code on the net which does do RPC based quota lookups. I'm toying with the idea of trying to modify rquota-rquotad to use this other code. However this is out of my area of knowledge so it will be an uphill battle ... so if reading quotas from NFS-mounted filestores will be coming Real Soon Now I'll probably just wait instead. So any ideas as to timescales, please?

[Dovecot] quota warning - take 2
by Nicolas Boullis 16 Jul '07

16 Jul '07

Hi, About one month ago, I sent a patch to this list to implement warnings when a user is close to reach his quota. I tried to follow Timo's advice to improve my code, and here (at last) is a new patch. Things I did not fix: - This patch is still for dovecot 1.0, as I will need warnings with dovecot 1.0. I may rewrite it for CVS HEAD in the future but can't promise. - I'm still using system() rather than fork()+exec()+waitpid() since I don't know a good time to run waitpid(). Comments are welcome. Timo, will you consider to add this to your unofficial patches? Cheers, Nicolas Boullis

by Timo Sirainen 15 Jul '07

15 Jul '07

http://dovecot.org/releases/dovecot-1.0.2.tar.gz http://dovecot.org/releases/dovecot-1.0.2.tar.gz.sig Fixes several bugs. This release also adds compatibility with upcoming Dovecot v1.1 so it'll be possible to upgrade to v1.1 and back to v1.0.2 without anything breaking. * dbox isn't built anymore by default. It will be redesigned so it shouldn't be used. + Maildir: Support reading dovecot-uidlist (v3) files created by Dovecot v1.1. - Maildir: "UIDVALIDITY changed" errors could happen with newly created mailboxes - If "INBOX." namespace was used, LIST returned it with \HasNoChildren which caused some clients not to show any other mailboxes. - Maildir++ quota: If multiple processes were updating maildirsize at the same time, we failed with "Unknown error". - IMAP: IDLE didn't actually disconnect client after 30 minutes of inactivity. - LDAP passdb/userdb was leaking memory - deliver: %variables in plugin {} weren't expanded - deliver: Don't bounce the mail if Sieve plugin returns failure

[Dovecot] How to stop POP clients from downloading mail after directory corruption
by Frank Church 15 Jul '07

15 Jul '07

Transferring my email from a Courier server, as well as some corruption in my dovecot installation caused all POP mails to be downloaded again. I surmised that the dovecot-uidlist file was not present in the first instance, and was probably out of sync in the second. Is there a way to do some reindexing and uid-list regeneration that can stop the problem from occurring? - Frank

[Dovecot] More Descriptive Logging Needed
by Joseph D. Wagner 15 Jul '07

15 Jul '07

(Everything herein refers to dovecot-1.0.1.) I'm sorry to say that I've been having troubles with dovecot. While attempting to troubleshoot them, I've found the existing logs to be lacking. In particular, I've had a lot of difficulty with the client<->server connection disconnecting, but the only message I get in the logs is "Disconnected". After dissecting the code a bit, I've found quite a number of places where the code will close the connection logging nothing more than the word "Disconnected", or worse, it will not specify a reason in which case the code in client_destroy() will log the default "Disconnected". Because of this, isolating the offending code has been a bit difficult. (I realize the problem may lie with the client, but I cannot even begin to program a work around until I isolate the exact place and cause of failure.) In an attempt to change the logging to be more descriptive myself, I already changed src/imap/cmd-fetch.c:85 on my own copy of dovecot from: client_disconnect(cmd->client, "Disconnected"); to: client_disconnect(cmd->client, "Disconnected in FETCH"); This makes the logging both more descriptive and more in line with other parts of code, like src/imap/cmd-append.c:50 which already say: client_destroy(client, "Disconnected in APPEND"); As luck would have it, my problem was not in the FETCH command. I'm now looking at the client_read() function in src/imap-login/client.c:318-334. If I'm reading the code right, then "i_stream_read(client->input)" returning "-1" means that the socket/stream is already disconnected, right? In other words, some function attempted to read off of a socket/stream that was already closed, right? If so, shouldn't the client_read() function not have been called in the first place? Please let me know if I'm wrong. I've been banging my head against the wall trying to make sense of all the different code. Any assistance you can offer would be appreciated. Joseph D. Wagner

[Dovecot] problem with subscriptions file version 1.0.1
by Liz 13 Jul '07

13 Jul '07

Hello, I am currently working on a patch to add IMAPdir support to dovecot. (For those who do not know, IMAPdir is exactly like Maildir except that instead of having a folder .foo it would just be foo. The advantage is that the file system is slightly easier to search through without the dot in front of the folders.) The first thing I did was get the configuration file working for Maildir. So I know that the problem has nothing to do with the configuration file. Next I looked through the actual source code to find any place where a dot might be added to the beginning of a folder. It transpired that there is a constant, MAILDIR_FS_SEP_S, which is assigned the value ".". I deleted all the occurrences of this constant, compiled the source code again, and ran into a rather interesting problem. When I try to create a new folder through Thunderbird on a separate machine, the folder is not visible unless I restart Thunderbird. I checked on the machine acting as a server and the folder is created and the subscriptions file is updated, and the dot at the beginning is indeed absent. So I see no reason why this should not work. If I had deleted some of the constants that ought not have been deleted, the subscriptions file would not be readable at all and I would not be able to see the folder when Thunderbird restarts. If there were some sort of deadlock going on with the subscriptions file, one would think that it would not be caused by deleting the constants. I would have run into the problem before editing any of the source code. I know for fact that the only thing different about my source code and the code available for downloading is the deleted constants. If anyone has any ideas, please let me know. If you need more information, please feel free to prompt me for it because I have no idea what might be useful that I have not already provided. Regards, Elizabeth Bermel

[Dovecot] telnet to dovecot not creating mbox
by Andy Fadich 13 Jul '07

Hi, Whenever I create a new email user, telnet fails until an email is sent to that user to create his mbox. This is the error that it gives. Anyone know how to fix this? I could create the email account script to touch the users mbox, but I havn't needed to do this in the past with ipop3d and dovecot on a different server.

[Dovecot] Maildir and Windows NFS server
by Julian Jimenez 13 Jul '07

13 Jul '07

Hi, I want to migrate form Courier to Dovecot. The problem is that our NFS server is a Windows server. We use Debian stable (Etch) and maildir. With Courier, we need to compile from the source, changing the parameter MDIRSEP from ":" to ";", because Windows cannot handle files with this character in their name. Anyone knows the name of the parameter in Dovecot that I need to change to do the same? Thanks in advance. Julián

[Dovecot] Dovecot login failing
by Richard Ellis 13 Jul '07

13 Jul '07

Fedora 7 Dovecot version 1.0.1 Hi All, I've been using a combination of getmail/Dovecot/Squirrelmail for a while now and its all been fine. However, last week when trying to demonstrate how to use Squirrelmail to my wife, her login failed. I then tried mine, which I had used many times before and it also fails. Looking in the logs, Dovecot appears to be trying to add a domain name against the login, instead of just checking that user against the UNIX logins of my machine. I thought at first this was because when I'm away from home, I use a no-ip address to access my mailserver, but it also fails when I'm in the house, or even on the server console. dovecot: Jul 12 12:04:56 Info: imap-login: Aborted login: user=< rick(a)servehttp.com>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff: 127.0.0.1, secured dovecot: Jul 12 12:10:00 Info: pop3-login: Login: user=<rick>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Anybody any idea how to rectify this? I can't see an option in the /etc/dovecot.conf file to stop it and using auth_default_realm = doesn't seem to make any difference. If I telnet into dovecot using my local username and password, it works fine. Any advice would be most welcome before I break it fiddling. Thanks Rik -- The Truth is out there, does anyone have the URL?
