[Dovecot] Dovecot 1.0-stable .deb file?
by Ian R. Justman 06 Mar '05

06 Mar '05

Hi, all. I know that there's no official Dovecot 1.0-stable .deb, given Timo's recommendations. However, does anyone have even an "unofficial" deb of it for, say, Sarge? I want to use 1.0's ability to use both mbox and maildir; the latter is very helpful for dealing with mailing lists. Thanks in advance for any help. --Ian.

[Dovecot] Password scheme overides
by Andrew Hutchings 06 Mar '05

06 Mar '05

I notice in the wiki you can have password sceme overides (such as {PLAIN}password). Would this work with the password fields in SQL databases (as it isn't clear in the wiki or conf file)? Regards Andrew -- Andrew Hutchings Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] dovecot-pgsql.conf can't find in chroot? (debian)
by Matthew J. Harmon 06 Mar '05

06 Mar '05

In my original email I noted that the directory /usr/local/etc was in the dovecot.conf variable valid_chroot_dirs : valid_chroot_dirs = /usr/local/etc:/etc:/var/mail:/lib Is that not sufficient? Under the /var/run/dovecot directory the directories ./usr/local/etc exist with dovecot-pgsql.conf in. Is there some big RTFM item I'm missing here? -Matthew P.S. - email address changed due to problems with upstream, will jump back as soon as this is fixed so I can finish my migration :) On Sat, 2005-03-05 at 09:06 +0100, Gunter Ohrner wrote: > Am Samstag, 5.

[Dovecot] Still having problems deleting messages through IMAP
by Doug Eubanks 05 Mar '05

05 Mar '05

Hello, I am using SquirrelMail with the 1.0 releases, and I have even backed up to the latest stable release based on 1.0. I am using MailDirs. When I delete a message, the message still shows up in the message list until either I log out and back in or a new message arrives in that folder. Any ideas? Thanks Doug Eubanks doug(a)simflex.com The speed of time is one-second per second.

[Dovecot] mbox or maildir?
by Brian Read 04 Mar '05

04 Mar '05

I am using dovecot in an SMEServer (aka e-smith), and recently backed-up on one system and restored on another system the imap email directories. The trouble was that dovecot "guessed" the mail type wrongly, and I ended up with "empty" ~/Mail directories (did it create or populate these?), and full, but ignored ~/Maildir directories for every user. Could someone point me to the chapter and verse of how (and when) dovecot decides which type of mail is in use, and how you can change the decision. I tried editing /etc/dovecot.conf, but that didn't seem to make any difference. Using dovecot 0.99-10 under a Redhat 7.3 base on kernel 2.4.20-18.7 -- Cheers Brian http://www.abandonmicrosoft.co.uk

[Dovecot] Dovecot response to "FETCH" command
by Alex Tang 04 Mar '05

04 Mar '05

Hi folks. I just converted my site from UW+mbox to dovecot+maildir (stable-test59, 2005/02/25). For the most part, everything is great. The server seems faster and less memory intense than the UW server (this part has made me very happy). And it's definitely more user friendly to me than Courier. There is one thing however... A few of my users are using the web based mail reader (Squirrelmail-1.2.11) that i provide for them. Once i converted to dovecot, the squirrelmail users were reporting that when viewing the folder list page, 2 things were happening: * The date for all of the messages was being displayed as "Sun 4:00 pm" * all messages were shown as being "new". they never would be transferred into the "Seen" state. After doing some IMAP protocol sniffing, i found this difference in the way that the UW server and the dovecot server handles the "FETCH" command... Squirrelmail issues a FETCH command to get message header information like this (lines broken with backslashes for readability): A009 FETCH 1:1 (FLAGS RFC822.SIZE INTERNALDATE BODY.PEEK \ [HEADER.FIELDS (Date To From Cc Subject X-Priority \ Content-Type)]) The UW server returns: * 1 FETCH (FLAGS () RFC822.SIZE 710 \ INTERNALDATE "27-Feb-2005 23:50:42 -0800" \ BODY[HEADER.FIELDS ("DATE" "TO" "FROM" "CC" "SUBJECT" \ "X-PRIORITY" "CONTENT-TYPE")] {153} Date: Sun, 27 Feb 2005 23:50:42 -0800 From: root <root(a)scorchedearth.us.proofpoint.com> To: altitude(a)scorchedearth.us.proofpoint.com Subject: asdf When the same FETCH response is returned by dovecot, the response looks like this: FLAGS () RFC822.SIZE 3358 INTERNALDATE "27-Feb-2005 07:55:27 -0800") * 1 FETCH (BODY[HEADER.FIELDS (DATE TO FROM CC SUBJECT X-PRIORITY CONTENT-TYPE)] {205} Date: Mon, 28 Feb 2005 00:04:22 +0800 From: xxx xxx <xxx(a)xxx.com> To: dovecot(a)dovecot.org Content-Type: text/plain; charset=UTF-8; format=flowed Subject: [Dovecot] "not listening" notification I noticed that in the UW response, the "* 1 FETCH ..." is the first line, and contains all of the data except for the message header info. However, in the dovecot response, the data is split into 2 lines, and the first line is not the "* 1 FETCH" line. In reading through the squirrelmail source, squirrelmail is not recognizing this as a valid response, and thus the date, size, and flags are not being properly set in the internal squirrelmail message objects. This explains why both the date as well as the "seen" status of the message is never properly set. OK, after all this blabbing on...here's my question. Is the data being sent back by dovecot a valid response? My knowledge of the IMAP protocol is weak to say the least. I tried reading the IMAP RFC (3501), in particular section 6.4.5 which defines the FETCH command), and the RFC seems to specify that the response should have the "* # FETCH" lines come first. However, the RFC seems vague, and i didn't wade through any of the other RFCs out there. I figure it is legal, since the two other clients i've used seem to understand it just fine (thunderbird/mozilla, mutt). However, could this be the reason why mozilla/thunderbird sometimes gets the message size wrong (and hence why the "tb-negative-fetch" workaround is needed). For now, i'll bang on squirrelmail to support the response sent by dovecot. Thanks. ...alex...

[Dovecot] hanging imap... and users getting other users' emails!
by Josh Burley 03 Mar '05

03 Mar '05

Hi All, We recently upgraded from UW (boy, starting to sound like a broken record, eh?)... Two problems: 1. Every two or three days users are unable to access their email via IMAP. It seems that it's because dovecot-auth has hung. Has anyone seen anything like this? 2. (the really serious one)... one of our users, "angie" has twice had her Outlook download other users' email! Once as another user, "helene", and just now as "mkarlin". The first time she got 800 of helene's email, and just now, about 30 of mkarlin's.... from our log, I noticed: Mar 2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:11 core pop3-login: Login: angie [::ffff:68.231.223.128] Mar 2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Mar 2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2] Our server setup: Fedora Core 3. dovecot-0.99.13. OpenLDAP, and dovecot auth'ing off PAM (mostly default setup, using Mailbox, and mail/ as a subdir). Any ideas? Any more debug info I can supply? .josh

[Dovecot] selective POP3 user
by Barry Kwok 03 Mar '05

I want to know if it is possible to limit some users to use POP3 service only in a server running BOTH IMAP and POP3 service. In other words, some users can choose IMAP or POP3 and some users can only use POP3. Barry

[Dovecot] Several issues with 1.0-stable
by Remy Zandwijk 03 Mar '05

03 Mar '05

All, We have Dovecot 1.0-stable deployed in our 3000 users environment as of last weekend. Up untill now, I have 3 issues: - When stopping Dovecot with: kill -TERM `cat /var/run/dovecot/master.pid`, the 'dovecot' process itself dies, the 'imap-login' processes die, but the 'imap' processes (there are a lot of them) don't die, but become a zombie. I think the way I stop Dovecot is the way to do it. The zombies can be killed by doing a 'pkill -9 imap', but that's not quite elegant. - Dovecot is running in a Solaris 9 environment. It turned out that Dovecot crashes when more then 256 filedescriptors are being used. This is rather normal, since Solaris only support 256 descriptors per 32-bit process. After starting Dovecot, I do a 'plimit -n 8192, 8192 `cat /var/run/dovecot/master.pid`, which allows Dovecot to have 8192 filedescriptors. Timo, is it possible to introduce a config file option to configure the number of descriptors? - Pine and Outlook users don't see the adresses or names of the people who sent them email. In my email yesterday, I said I remembered that tests with Dovecot 0.99 showed no problems. Today, I installed both Dovecot 0.99 and 1.0-stable on my test box. It turned out that 0.99 indeed works OK and that 1.0-stable is the problem. The user mailboxes are 'Maildir'; we do not use mbox format. I like to see this problem being fixed..... We have 2 namespaces in our setup: the default namespace and a namespace which location is set to ~/.Mailstorage. When not using a prefix in the email client setup, users can make new email folders in the default namespace and the 'Mailstorage' namespace. We want users only to create mail folders in the Mailstorage namespace, not in the default namespace. Questions: - Is it possible to force a prefix to clients? - If not, is it usefull to have an option in the namespace configuration that allows or disallows the creation of mail folder? If so: consider this as a feature request. Thank you for reading, best regards, Remy Zandwijk Free University of Amsterdam The Netherlands

I am upgrading from uwashington's imap server, and in theirs I had to put a directory "mail" in for the imap folder (this is on the client). The problem I have is with dovecot this makes an extra level (I think). So on my server ~/mail is where the mail folder is located, but when the client puts in the "mail" for the imap server directory dovecot looks in and creates folders in ~/.mail/mail. This is a problem for me because I have many clients and I would have to go reconfigure each one. My question is this, is there a way to make dovecot look in ~/ so that when combined with the imap folder from the client it ends up in ~/mail? I hope that is clear enough, I was thinking maybe I need to set default_mail_env, but i have no idea to what? Thanks in advance Troy

[Dovecot] Trigger getmail via mail-client action?
by Gert Brinkmann 03 Mar '05

03 Mar '05

Hello, I want to use dovecot on my private debian/unstable-system to have the advantages of an IMAP-Server (Access to mails from different computers, Simply changing the mail client). I decided to use dovecot, because I very often have read (in the web) that it should be more simple to configure than other servers. Now I have the following question: I want to use getmail to retrieve mails from my provider's pop3-server. I do have a dial-up-connection that is not online permanently (I do not have a flat rate). I could start a script on ppp's ip-up that periodically invokes getmail and on ip-down to kill it again. But I would prefer to invoke getmail only when I really want it to be run. The ideal solution for me was to invoke getmail when the "Get Mail"-Button of the mail client is pressed. Is this possible? Perhaps there is something like a connection- or refresh-trigger in dovecot? Thank you, Gert

Martin, we're dealing with the same problem right now. We are using dovecot 1.0 stable and we migrated last weekend. 32-bit processes in Solaris 9 have 256 filedescriptors avail- able. This seems a bit to small. Using this command to get the number of file descriptors used by dovecot: ls -1 /proc/`cat /var/run/dovecot/master.pid`/fd | wc In our enviroment this is currently around 390. You can limit the number of file descriptors per process in Solaris 9. After starting Dovecot, we issued the command: plimit -n 8192,8192 `cat /var/run/dovecot/master.pid` This gives Dovecot 8192 filedescriptors. HTH, Remy

[Dovecot] Protect some mailbox to remove
by FireFly 25 Feb '05

I've installed dovecot 0.99.14 (maildir, postfix, RHEL3) and I would like to create , for every user, 4 mailbox (in skel): mail-sent, spam, virus-alert and sysadm. Procmail, parsing header mail, will move mails into a specific mailbox. Every users could move, delete, read these mails but they must not delete mailbox folder (such as INBOX mail).

[Dovecot] APOP
by Steven Stern 25 Feb '05

25 Feb '05

I want to turn off POP3 and use POP3S in its place. So far, it's working well for Outlook and Thunderbird. But I'm running into problems with Agent: It supports APOP but not POP3S. Is there a way to have Dovecot support APOP authentication on a normal POP3 connection? I'm running 0.99.13 on Fedora Core 3. -- Steve

[Dovecot] A few words about NFS please?
by Jeff A. Earickson 25 Feb '05

25 Feb '05

Hi, Could you say a few words about Dovecot and POP/IMAP to an NFS mounted filesystem? I thought I saw on the dovecot webpage that NFS is "no way" with 0.99 and "maybe" with 1.x. I was looking for the FAQ and couldn't find it. My setup is like so: My mail server is a Solaris 9 system, running sendmail/procmail, and qpopper POP. Mail is stored in mbox format. The /var/mail filesystem is NFS exported to another Solaris 9 system that runs UW-IMAP. The user community also has login access to this second system, so there are also local email clients like Pine and emacs using the NFS /var/mail. So, POP and sendmail/procmail accesses /var/mail locally, while UW-IMAP accesses it via NFS. The user community has been warned to do either POP or IMAP, but not both. There are very few problems with this setup. I would like to use Dovecot for both POP and IMAP on the two machines. I know NFS is frowned upon, but this has worked for me. Comments and suggestions, please? Jeff Earickson Colby College

I have dovecot running with postgres backend. I am exceeding my maximum database connections (currently 40) with dovecot 0.99.10.9 and postfix and was wondering if dovecot has a parameter to limit the total number of database connections that it will create. Dan

Hi guys, Just tested yesterday's stable build, when including SQL into the build I am getting an error on like 86 of passdb-sql.c (passdb_result = PASSDB_RESULT_OK;) It rightly says passdb_result is undeclared.

[Dovecot] Problems with Dovecot and self-signed cert
by Seth Bokelman 22 Feb '05

22 Feb '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've recently set up a Red Hat Enterprise Linux 4 WS server, and decided to try using Dovecot as my IMAP server, as I was impressed with the dedication to security that seems to be the core development goal. I'm really happy with it, but I can't get it to work with a self-signed cert. Normally, on a RHEL system, you just go into /user/share/ssl/certs/ and type: make whatever.pem Then you fill out the various address fields, and you've got a cert. However, when I rename/delete the existing dovecot.pem and generate a new one using this method, Dovecot won't start and I'm unable to connect to the box. The cert that it's currently using is called "localhost.localdomain", and while that works, mail clients gripe every time about the domain name not matching the certificate. I've looked through the RHEL documentation, and it appears I'm doing everything correct. Anyone have any suggestions? - -- Seth H.

[Dovecot] uw-imap and gnu-pop3d to dovecot transition/replacement
by Jani Karlsson 22 Feb '05

22 Feb '05

Hi I am trying directly to replace old uw-imap + GNU pop3d with Dovecot. Problems I am having with new (1.0-stable 22.02.2005) are: - How to get SSL working with new config? imaps_listen doesn't exist anymore. cannot add protocol imaps for some reason. - need to get Dovecot run on another port the test-phase, ie 144 for imap, 994 for IMAPs - need to use .mailboxlist (modified the source already, this maybe works - due SSL problem not tested?) - no symlinks etc can't be done (simply too many mailboxes) so how to make dovecot read IMAP-directories from user's homedir.. Anything else I should know before trying this transition? All help truely appreciated. Jani. (Mailbox count is high which why transition to faster postclient-server software is necessary - or adding few more dual CPU-servers.. and doing anything but editing config/such by hand is not a option.)

Im now trying an SME server installation with dovecot 0.99.10, and when i delete a message, it gets marked as deletet, but as soon as i change the mailbox the mail gets also expunged from it. is this a bug fixed in the newer dovecot releases ? or is this a feature that i can configure ?

[Dovecot] Bug?: Authentication still doesn't work with imap-login
by Peter Franck 21 Feb '05

21 Feb '05

I tried digging it all through. I can't find a solution. The problem pops up in auth-master-connection.c in function master_input_request. It does a auth_client_connection_lookup with the "client_pid" (which behaves as a counter, where i would expect a constant process-id...) Something is very wrong with this PID. Maybe someone can explain the Master <--> Auth IPC to me so I can understand and fix it myself? Where does Master take this client number from?

[Dovecot] Dovecot SSL-Certificate
by Adam Pordzik 21 Feb '05

21 Feb '05

Hello, I've a not really dovecot specific problem with my certificate. Since the OpenSSL documentation isn't what I expect to be at least good, I hope someone here can give me a hint how/where fo fix it; I've created a root-Certificate with almost untouched openssl.cnf and issued a server-certificate for dovecot. This cert and it's key I placed in somewhat like /var/dovecot. To state explicitly, away from it's superior root-cert. So, a: openssl s_client -connect server.tektoform.lan:993 -showcerts ends up in: unable to get local issuer certificate. Althougt connections from clients are working, I prefer to set it up cleanly. Does openssl-clientlib looks up for openssl.cnf, where the place of root-CA-cert is denoted, or do I have to put all cert together in a single directory, or, or, or ...? Or to be more verbose for "openssl s_client": CONNECTED(00000003) depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=27:certificate not trusted verify return:1 depth=0 /C=DE/ST=Hamburg/L=Hamburg/O=d-dt/OU=lan/CN=server.tektoform.lan/emailAddress=hostmaster(a)tektoform.lan verify error:num=21:unable to verify the first certificate verify return:1 --- Thanks for your comments.

[Dovecot] Re: Need 2 additional folders like INBOX for JUNK and INFECTED mails
by Mirko Schulze 17 Feb '05

17 Feb '05

Hi there. I've solved now the problem, but it's not really fine yet. The "special-folders" are undeletable in the filesystem, but the Mailclient displays different errormessages for the same action. I've modified following source files. The new additional lines are similar to the INBOX "lines" /src/imap/cmd-list.c: 63 /src/imap/cmd-delete.c :20 /src/lib-storage/index/maildir/maildir-storage: 294,308,437,601 Notice that the linenumbers are not really correct, because of the deferrals by inserting new sourcecode. The new problem is, that the mailclient displays incorrect error messages. When i use another folder caching method i'll get no errors. Perhaps someone has a better solution, than i? Thanks Mirko

[Dovecot] Speed up large maildirs
by Leen Besselink 16 Feb '05

16 Feb '05

Hi, I'm very fond of maildirs, they are simple, I like that. But I've never really understood the significance of maildir/new/. The only use I can see is that (for example in the case of dovecot), you'd move a message from new to cur and then update the index-file, that's it. So to make put it more direct, you'd know when and with what to update the index-file, based on where the file resides. I've never been bothered by them, until I found that that is the last hurdle for fast access to a large (and receiving a lot of mail) Maildir. I've been thinking long and hard about what to do to make them work even better. My idea at this point is the following, use maildir/new as little as possible, just use it for what it was intented and spread the time of updates. If someone would make a wrapper-program around the delivery-program (like qmail-local, vpopmaildeliver, procmail or local and virtual from postfix) and the delivery program would print to standard output the path+filename it saved a (or more) message(s) to, the wrapper would be able to send an update-message to a dovecot-daemon. That mean, updates are small, and opening a large maildir would be sped up. How does that sound ? I hope this is a helpfull suggestion. _____________________________________ New things are always on the horizon.

[Dovecot] Why am I getting more imap folders?

Can I not just have imap view and use the ~/mail files? Is this normal? Can I have it set up to use the maildir files that are already there? It used to work that way but I guess that is with the other imap server that came with fc1.

[Dovecot] changing user mail folders

I have a working dovecot server with user mail in Maildir:~/Maildir What is the proper way to change the location of user mail to /var/mail/username to take advantage of a large /var drive space? Would you recommend adding the creation of new user directories in /var/mail to my Redhat "adduser" script to get the permissions correct? Or via some other method? Also, any idea how to make Postfix deliver mail to the the new user directories? Thank you for any help and for a great product. Jason

[Dovecot] Need 2 additional folders like INBOX for JUNK and INFECTED mails
by Mirko Schulze 15 Feb '05

Hi there, i need for JUNK & INFECTED mail two folders like INBOX. The folders must be fixed in naming, permissions and so on. I've adjusted some commands in the ./src/imap folder. But it's work not really fine: Creating a folder works, but deleting too. *smile* Moving a "special-name-folder" (f.e. from Trash) to its correct place, Dovecot says, that the folder is currently there. subsribing / unsubscribing doesn't work, too. ... ... ... I think that this is a "standard" problem for much people, who don't want, that the users will delete files through the imap protocol. Are there any solutions? Thanx Mirko

[Dovecot] 0.99.14 released
by Timo Sirainen 15 Feb '05

15 Feb '05

One more change since -rc3 (the last one in list). v0.99.14 2005-02-11 Timo Sirainen <tss(a)iki.fi> - Message address fields are now parsed differently, fixing some issues with spaces. Affects only clients which use FETCH ENVELOPE command. - Message MIME parser was somewhat broken with missing MIME boundaries - mbox: Don't allow X-UID headers in mails to override the UIDs we would otherwise set. Too large values can break some clients and cause other trouble. - passwd-file userdb wasn't working - PAM crashed with 64bit systems - non-SSL inetd startup wasn't working - If UID FETCH notices and skips an expunged message, don't return a NO reply. It's not needed and only makes clients give error messages.

[Dovecot] Help, problems with permissions

Hi I am replacing my current mail system, using Exim/Postgres/WU-IMAP to another host using Dovecot. Everything has gone well, until I have tried to access some test mails via POP. The error message I am getting is Feb 14 03:03:57 wpc1273 pop3(simonw(a)orion-w-t.co.uk): lstat (/home/dovecot/users/orion-w-t.co.uk/simonw/cur) failed: Permission denied Feb 14 03:03:57 wpc1273 pop3(simonw(a)orion-w-t.co.uk): Couldn't open INBOX: Internal error occured.

Hi Thank you for the reply. The documentation on the wiki/dovecot site clearly provides an example exim transport statements showing mail writes as dovecot/dovecot with permisions of 600. The mail system uses virtual users, and I have provided mail/group ids of 1001/1001. The current directory tree is /home - owned by root /home/dovecot - owned by root /home/dovecot/users - owned by root, 777 /home/dovecot/users/DOMAIN - owned by 1001:1001, 777 /home/dovecot/users/DOMAIN/USER - owned by 1001:1001, 777 /home/dovecot/users/DOMAIN/USER/cur - owned by dovecot:dovecot, 600 /home/dovecot/users/DOMAIN/USER/new - owned by dovecot:dovecot, 600 /home/dovecot/users/DOMAIN/USER/tmp - owned by dovecot:dovecot, 600 Can you confirm that all files should be owned by 1001/1001? What permissions should should exist on these directories/files?

[Dovecot] Problems with dovecot using Maildir on JFS.
by Jacob Robert Wilkins 12 Feb '05

12 Feb '05

Howdy, I have dovecot installed on CentOS (rhel3 clone), and I'm using Dag's dovecot package. I have postfix setup to deliver to Maildir, in /home. The /home volume was formatted with JFS. In this setup, both Outlook and Thunderbird would not show any new mail unless they were completely shutdown and restarted. I have moved /home to an ext3 formatted and all is well. Anyone have any insight on this? Thanks, jrw

[Dovecot] outstanding issues with 0.99.13
by sean finney 10 Feb '05

10 Feb '05

hi list, i'm in the process of testing dovecot before a hopeful switchover from uw-imap/qpopper to dovecot, primarily to get off of the uw-imap/mbox combo and moved to Maildir. i think we've worked out the logistics to avoid any service downtime, with only a short window of a few minutes per user for when we convert from mbox to maildir format. however, during testing a few issues have come up, some of which i've been able to work around, others which i haven't. for those that i have been able to work around, i'll include my solution so that fellow googlers may profit, and for those that i haven't i'd really appreciate your feedback. logistical problems: 1 - automagic detection and uw-imap inbox in ~/mbox. i'm not sure if this is a default characteristic or if it's specific to us, but our spool is in /var/mail/foo and inbox in ~/mbox. the automagic Maildir/mbox detection doesn't find the "mbox", and i can't tell it where it is because then it doesn't look for the Maildir. solution: i wrote a small patch to dovecot's autodetect code to help it find the location of our mailboxes. if anyone would like a copy of said patch i can send it off list. 2 - uw-imap's spool/inbox message moving. i read from the wiki that this isn't a feature currently being worked on. solution: deliver all mail to the same place. since we use procmail as our MDA, this isn't too hard of a problem. basically we redirect mail to the inbox and redeliver everything in the spool. 3 - supporting multi-homed services + ssl. for historical reasons we provide services from multiple hostnames (mail.foo, imap.foo, etc). with ssl, that means a different cert for each, otherwise some clients will break. solution: we're spawning off three seperate dovecot instances, each using a different config file. not the most graceful, but it works... application problems: 4 - dovecot imap + ms lookout 2002 + deleting messages. i'm not sure if this is an app or server side problem. basically, a user will delete a message, only to have it reappear in the mailbox a short time (few minutes) later. if i monitor the state of the mbox file, no changes are made to it until the user selects "empty trash", after which point they are expunged. looking at a protocol dump, i see the client setting the deleted flag on the message when they originally delete it. here's an excerpt: <snip> tg7i OK Idle completed. 6gzd UID STORE 30021 +FLAGS (\Deleted \Seen) * 51 FETCH (FLAGS (\Deleted \Seen \Recent) UID 30021) 6gzd OK Store completed. stpw IDLE <snip> i'm not too familiar with imap, but it looks like the server is caching the deletion request and then forgetting later forgetting about it? i have all the "client workarounds" enabled, fwiw. solution: ??? 5 - mac os x + eudora + deleting mail. a different problem alltogether. in eudora deleting a mail seems to immediately move it to the "trash" mailbox, so the above problem does not occur. what *does* happen is that if a user rapidly deletes messages one-by-one, an error message pops up about UID's not existing. i haven't gotten a full description of this problem, but here's an excerpt from what i think is the symptom: <snip> A00109 UID COPY 30002 Trash A00109 OK Copy completed. A00110 UID STORE 30002 +Flags.silent (\Deleted) A00110 OK Store completed. A00111 EXPUNGE * 31 EXPUNGE A00111 OK Expunge completed. <snip> and later: <snip> A00040 UID FETCH 30002 (UID BODYSTRUCTURE) A00040 NO Some of the requested messages no longer exist. A00041 UID FETCH 30002 RFC822.SIZE A00041 NO Some of the requested messages no longer exist. A00042 UID FETCH 30002 (BODY.PEEK[]) A00042 NO Some of the requested messages no longer exist. <snip> which i suppose is correct that it doesn't exist (since it was moved out of the inbox). however, eudora does not have this problem with uw-imap, and i'm wondering what might be causing it? solution: ??? okay, i think that's everything that i've ran into. we're still pushing ahead with this because we need to get the hell off of uw-imap/mbox, but i don't think we'll be able to stick with dovecot if these are unresolvable issues. in that case, we'll probably use dovecot with these minor nuisances while we transition, and then perhaps use courier in the long run. hopefully that won't have to be the case though :) if anyone has any experience specifically with "5" and "5", i'd really, really like to hear about it. in the meantime, i'll continue to test other things, and also see if the problem also persists when mail is stored in Maildir format. anyway, thanks for your time! sean

Timo Sirainen noticed Edgardo Pezoa was using MH style filenames. And I did the same thing. My main inbox configured in procmail was $HOME/Maildir/new and it should be $HOME/Maildir/ (notice the slash at the end). Now, new mails have filenames such as 1107960126.14681_2.hive:2, instead of msg.uC:2,S. I never had this problem with courier so I didn't thought it could be a configuration error.

[Dovecot] Corrupted index file w/Procmail in FC2
by Edgardo Pezoa 09 Feb '05

09 Feb '05

Hello: We have a Fedora Core 2 (FC2) server with Dovecot and Procmail. Versions are: dovecot-0.99.13-4.FC2 procmail-3.22-13 We use "maildir" below home directory like: /users/operaciones/epezoa/maildir, where "epezoa" is my account. If I receive an e-mail, is stored at "new" folder. When I try to get e-mail from server, message is transfered from "new" folder to "cur" folder, but I can't see my e-mail and Dovecot generates a "Corrupted index file" in log file: Feb 8 14:02:34 dlp1 pop3(epezoa): Corrupted index file /users/operaciones/epezoa/maildir/.INBOX/.imap.index: index.next_uid (14836) > uid_rec.uid (14825) But, If I receive another e-mail (at "new" folder) and I try to get messages, I get both. My clients are Mozilla (with "pop3") and Squirrel (from another server with "imaps"). Both have same behavior, so I think client is not involved in this problem. MTA is Postfix, but all accounts works well, except who use Procmail. I read about locking in Procmail and Dovecot and I think locking may produce this problem, but I can't find what's wrong. I upgraded dovecot from dovecot-0.99.10-5 to try fix this. Thanks in advance, -- Edgardo Pezoa

Among other things I started working half-time at Movial (www.movial.fi) I had forgotten 8 hour work days at office could take so much time :) Anyway.. There has been a few changes since RC1 so I'll still make RC2 before the final. Changes since RC1: - passwd-file userdb wasn't working - PAM crashed with 64bit systems - non-SSL inetd startup wasn't working - upgraded setuid/setgid initialization code from 1.0-tests

[Dovecot] Corrupted index file
by Frank Hart 09 Feb '05

09 Feb '05

I've recently switched from Courier-imap to dovecot and I'm impressed with it's speed and reliability. However, my index file gets regularly corrupted: Feb 8 21:23:16 hive imap(hart): Corrupted index file /home/hart/Maildir/.INBOX/.imap.index: index.next_uid (129) > uid_rec.uid (128) dovecot version: 0.99.13-3 Debian sid) I use dovecot in combination with mutt, procmail and postfix. If I rename the last received mail I can use my inbox folder again (until the next time the index gets corrupted). Debian bug# 294284 -- make install, not war

[Dovecot] Server going crazy!!!
by poohba＠blkpoohba.dyndns.org 09 Feb '05

09 Feb '05

I have dovecot-0.99.11-1FC3.4. I use Pine on the server and Outlook 2003 on remote computers to access IMAP and POP3 to access via my blackberry 7100t. It seems that after using IMAP and then going back to pine it somehow refreshes everything and all the messages are picked up on my blackberry once again as if the emails are new. So everything that is in my inbox is now pushed or grabbed by my blackberry as new messages when they are not and have been read already (at least most of them). Why is this happening? ## Dovecot 1.0 configuration file base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s imap_listen = [::] pop3_listen = [::] imaps_listen = [::] pop3s_listen = [::] log_timestamp = "%b %d %H:%M:%S " login_dir = /var/run/dovecot-login login_chroot = yes login = imap login = pop3 default_mail_env = mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_locks = fcntl auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root

[Dovecot] Multiple auth sections, stable branch - 7/2/05
by Andrew Hutchings 07 Feb '05

07 Feb '05

Hi, Great job with the dovecot 1.0 stable branch, much more stable than the test57 I was using. Only one slight oddity, I know multiple auth sections is not stable yet but I am finding that one auth section at random is being ignored at login time (acknowledges it at startup). The auth section that is ignored is the same each time, but different on each server I use it on and changes at random after modifying the dovecot.conf file. Used both my test57 (hacked to remove the auth command) conf file and a new one I created using today's stable branch conf file. I sorted a work around by duplicating the failing auth sectio with a different name in each server and it works great! :) If this is easy thing to fix, great, you are still our hero either way Timo, you have made our mail server -> cluster migrations much less painless.

[Dovecot] Migrating from mbox to maildir: Message ordering?
by Ian R. Justman 06 Feb '05

06 Feb '05

Hi, all. I have been playing with the notion of migrating some of my folders to maildir because it's a lot easier to manage that way from a reader standpoint. The big question I have is how do I maintain message ordering in each folder? When I use a mail program to do the migration from mbox to maildir, selecting "order received ascending", it works nicely, but one very small problem: When I go to look at the newly-populated folder, everything is in reverse order. I've tried it with T'bird and I've tried it with Pine. Both yield the same results. I'm thinking the issue might be with Dovecot. Or is it a peculiarity with maildir? Or am I better off using other means to convert a mbox folder to maildir? I like maintaining the message delivery order so especially items like mailng list threads can (normally) flow right. I don't always trust the message's date field because it CAN be faked (and sometimes is by the sender, whether accidental or intentional). And while we're on the subject, since maildir's a file-per-message mailstore, what happens to ordering when you delete a message and a new message arrives? However, otherwise, everything else is working beautifully. I haven't gone into bashing the living hell out of it to make sure it REALLY works The testing was done with Dovecot 1.0test62, Thunderbird 1.0, and Pine 4.62. Both mbox and maildir folderstores are on the same machine and Dovecot's configured to use both with a maildir in the user's directory, oddly enough, called "maildir", for their maildir store. Thanks in advance for any help anyone can render. --Ian.

[Dovecot] pam_mkhomedir and dovecot
by Ben Halicki 03 Feb '05

03 Feb '05

Hi all, Just wondering if anyone has successfully managed to configure pam_mkhomedir and dovecot, so that users home directories are automatically created? As far as I can tell, the login process runs as a non-root user, which results in a permission denied error while trying to create the users home directory. I'm not sure if this error is specific to dovecot or pam though. Any thoughts would be greatly appreciated.

[Dovecot] Dovecot doesn't call pam_open_session, thus dodging pam_mkhomedir
by Nicolas Lopez 03 Feb '05

03 Feb '05

I hit a small snag using Dovecot-imapd smoothly in my environment with maildir and most of my accounts in LDAP. Since the accounts are created through a web interface on another server home directories on the mail server don't get created automatically. There's the handy pam module pam_mkhomedir.so to automagically create home directories, but unfortunatly Dovecot wasn't calling pam_open_session to run the session setup pam modules. I made a small patch to passdb-pam.c to call pam_open_session between pam_acct_mgmt and pam_get_item and now I my home dirs are automagically created and everyone is happy. So, I figured I'd share the little patch in case someone else finds it useful. My patch doesn't properly close the session which will probably iritate more advanced session modules that actually have something to clean up, oh well. Aside from manually having to create home directories Dovecot-imapd has been working really well for us for a number of months, I just finally got around to dealing with the home dir creation issue. - Nick Lopez nlopez(a)espri.arizona.edu

[Dovecot] dovecot-stable branch
by Timo Sirainen 01 Feb '05

01 Feb '05

To confuse Dovecot versioning even more, I've added "dovecot-stable" module into CVS. This is a version of Dovecot before the recent keyword changes but with several bugfixes backported to it. It's thought to be mostly stable. I intend to keep it updated with important bugfixes and with other simple bugfixes. Although I'm not sure if I'll make a large code base upgrade once keyword changes are stable. This is mostly meant for people who _really_ want to use 1.0-test codebase in production right now. Perhaps it's already more stable than 0.99.x, but upgrading should probably be made easier for v1.0. The dovecot-stable module itself is just a hack that will go away at some point. Once the main codebase is stable enough for v1.0 beta release, I'll make a stable branch instead in the main dovecot module (and probably with different RCS than CVS).

[Dovecot] vpopmail oddities

vpopmail + qmail + dovecot + thunderbird = huge headache ;-) alright, when attempting to connect via imaps to my .maildir based vpopmail install, $user@$domain is having some problems. /var/vpopmail/domains/$domain/$user is the location of the user folders with vpopmail and yet dovecot isn't exactly passing on the domain :-\ i'm not sure if this is a pebkac issue or if it's the root of something far more evil, but this is really bothering me after about 4 days. i've got dovecot set to auth against vpopmail and i'm running a dovecot authd. i know that i've given very little information, is there any way that someone can ping me back requesting the particular information they need to properly diagnose this? -- ________________________________________ To avoid being added to my spam filter: 1.

[Dovecot] mbox vs maildir
by poohba＠blkpoohba.dyndns.org 01 Feb '05

01 Feb '05

I am a little confused and maybe if I figure this out I will be able to get this to work. I am now able to get my pop3 working but not imap. My inbox is in /var/spool/mail/%u and my mail directory is /home/%u/mail and then all the 'folders' are there which are actually files. Is that maildir or mbox? Which do I have to use for dovecot? Or can I use whichever I choose. I would like to keep the setup I have and use IMAP but i am finding this very difficult. I find some places that say I have to convert what I have and other places that say I don't. Can someone please break it down for me.

[Dovecot] How to run in debug format for SSL testing?
by Jeff A. Earickson 31 Jan '05

31 Jan '05

Help, new to dovecot... I want to get some output from my test sessions to confirm that SSL pop and imap are working. How does one get debug output from dovecot? How does one see that dovecot is using SSL in a transaction? I configured dovecot 0.99.13 with: CC=gcc CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl --with-rawlog --enable-debug > configure.out on Solaris 9. BTW, if I compile with Sun's StudioOne version 8 compiler, I get a core dump of dovecot-auth into /var/run/dovecot. The gdb backtrace looks like: gdb dovecot-auth core GNU gdb 5.2.1 Copyright 2002 Free Software Foundation, Inc. GDB is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions. Type "show copying" to see the conditions.

(gdb complaints about lack of debug symbols from numerous libs snipped out) Core was generated by `dovecot-auth'. Program terminated with signal 10, Bus error. #0 0x0002b64c in pam_child_input () (gdb) backtrace #0 0x0002b64c in pam_child_input () #1 0x00036c68 in io_loop_handler_run () #2 0x00035e5c in io_loop_run () #3 0x00025940 in main () The code works when compiled with gcc 3.4.3.

[Dovecot] Corrupted mailboxes
by Vincent Jaussaud 31 Jan '05

31 Jan '05

Hello, We are currently facing some weird problems, and although it may not be directly related to dovecot, I hope some of you guys may have a clue on this. We used to have a POP/IMAP server running Fedora Core1, with dovecot 0.99.13 (DAG). Everything was working fine, until an hardware problem forced us to install a new server, on another machine. We installed a fresh new Fedora Core 3 box, running both sendmail 8.13.1, procmail 3.22 and dovecot 0.99.13. Now, we are seeing strange errors in our dovecot logfiles. It seems to happen randomely, but always on the same mailboxes. The following error is logged: pop3(username): Jan 27 17:26:46 Error: Error syncing mbox file /var/spool/mail/szameitatd: LF not found where expected pop3(username): Jan 27 17:26:46 Error: Error indexing mbox file /var/spool/mail/username: LF not found where expected pop3(username): Jan 27 17:26:46 Error: Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-01-27 17:26:46] People having that problem are able to login, but cannot retrieve new mails. Clients simply says no new mails are available. We tried to remove completely the mailbox file, waiting for procmail to create a new, but after a few minutes, the problem happens again. We cannot reproduce the bug with a particular mail; it seems the problem come from nowhere. Verbosing procmail didn't helped either. The only way to fix it when this happens, is to manually edit the file, and remove the first line feed at the very beginning of the mailbox file. I saw one post in the mailing list with the same problem, and we tried the "mail_extra_groups = mail" workaround, but that didn't help either. I actually think this has nothing to do with my problem :) We have around 500 mailboxes, and only a couple of them (3-5) do have the problem. Any idea how this can happen ? Any suggestions ? Thanks !

[Dovecot] Problem with incorrect permissions with shared folders
by Dave Hatton 30 Jan '05

30 Jan '05

Hi, I'm seeing strange permissions when using an email client to create a new sub folder in a shared folder. This is dovecot-1.0test61 I have a directory /data/mail/shared owner=root group=shared permissions=2770 I have a file /data/mail/shared/dovecot-shared owner=root group-shared permissions=2660 User fred in in group shared (in /etc/group) My understanding is that now in my client I can create a folder called test and so I should have Folder /data/mail/shared/.test owner=fred group-shared permissions=2770 What I actually get is Folder /data/mail/shared/.test owner=fred group-shared permissions=2700 So dovecot doesn't appear to be honouring the permissions on dovecot-shared when creating folders. Also, when creating a folder in a shared folder should the create process automatically copy the dovecot-shared file down to the new folder to allow this to be shared as well? Thanks Daveh

[Dovecot] Problem using passwd-file authentication: does not read UID, GID
by Joseph Tam 30 Jan '05

30 Jan '05

There seems to be a problem when setting the default authentication method to passwd-file when they use the same file (which they frequently do): auth default { mechanisms = plain userdb = passwd-file /passwd passdb = passwd-file /passwd ... } The log files show dovecot: Jan 11 14:41:40 Info: Dovecot v1.0-test60 starting up dovecot: Jan 11 14:41:49 Info: auth(default): userdb(test,127.0.0.1): uid=0 gid=0 home= mail= dovecot: Jan 11 14:41:49 Error: Logins with UID 0 not permitted (user test) dovecot: Jan 11 14:41:49 Info: imap-login: Internal login failure: test [127.0.0.1] When userdb-passwd-file.c::passwd_file_init() is called, it compares the userdb passwd-file to the passdb passwd-file. If they are the same, it resets the time stamp to force a re-read of the password database during the next look-up. However, I believe it also needs to reset the userdb_pwf->userdb flag to TRUE or else it won't pick up the UID and GID and will use 0 instead: /* resync */ userdb_pwf->userdb = TRUE; /* Was FALSE in v1.0-test60 */ userdb_pwf->stamp = 0; Joseph Tam <tam(a)math.ubc.ca>

[Dovecot] STARTTLS and inetd
by Magnus Holmgren 30 Jan '05

30 Jan '05

Hi! When running dovecot from inetd (as per the instructions on http://wiki.dovecot.org/InetdInstall) imap-login and pop3-login thinks that TLS is enabled when in fact it isn't (we're connecting to port 110 and port 143, so the --ssl parameter isn't present). The reason for that is found in login-common/main.c:main(): > if (fd != -1) > (void)client_create(fd, &ip, TRUE); I added a flag which I set when ssl_proxy_new() is successfully called (see the following diff) and it seems to work fine.

[Dovecot] Dovecot shared folder woes
by Dave Hatton 30 Jan '05

30 Jan '05

Hi I'm new to Dovecot so please be gentle with me. I did a search through the list archives but couldn't quite work out my problem. I have Dovecot installed and running and I can connect to it from my email clients (Outlook and Evolution) ... so looking good so far. I would like to setup three types (groups?) of mail store 1. A per user - e.g. Fred, Harry, Betty. (For my purposes they all have Unix Accounts on the mail server) 2. A public store which can contain folders that may be read and written to by any user who is authenticated 3. A per group store (e.g. accounts, sales, marketing) that may be read and written to by any user who is authenticated and is in the specified group Firstly, should this be possible with Dovecot? I have tried the following dovecot.conf parameters which I thought should do the trick ... --------------------- cut ------------------------- ### this should give each user a mail store default_mail_env = maildir:/var/mail/%lu/%u/Maildir ### Create Public mail store namespace public { separator = / prefix = Public/ location = /var/mail/public inbox = no hidden = no } ### Create mail store for accounts namespace shared { separator = / prefix = Accounts/ location = /var/mail/accounts inbox = no hidden = no } ### Create mail store for sales namespace shared { separator = / prefix = Sales/ location = /var/mail/sales inbox = no hidden = no } --------------------- cut ------------------------- I then: 1. created the directories /var/mail/{public,accounts,sales} 2. chgrp each one to a group (public,accounts,sales respectively) 3. chmod 770 each one 4. created a dovecot-shared in each one - chgrp and chmod appropriately And then restarted the server Now my problem When I try to connect from a client it fails and the tcp/ip connection dies When I look in /var/log/mail I see and error 89 (which I understand is a generic error) and IMAP(fred): Failed to create storage for 'Public/' with data: /var/mail/public What and I doing wrong? TIA Daveh

[Dovecot] Help with Outlook2003 hanging on receiving email with attachments
by John Suter 30 Jan '05

30 Jan '05

I have one user running Outlook 2003 that hangs up when receiving emails with attachments. He is connecting using POP3. It's almost as if something is timing out and closing the connection. The client is on a 1500/256 DSL connection and the server is on a 768/768 fractional T-1. I have other users that connect with Outlook/POP3 without any problems. I have done a fresh install of Windows/Outlook to make sure it's not a client machine problem. Any help or ideas are greatly appreciated.

[Dovecot] maildir and /var/spool/mail/$USER
by Rob Campbell 29 Jan '05

29 Jan '05

I was told to use dovecot because it was easier than cyrus. I just upgraded from fc1 to fc3. I am not sure what fc1 used but I think it was cyrus and it worked perfect out of the box no configurations to do. The new cyrus-imapd is not so simple so I got dovecot. I see examples saying to use mbox=~/mail:INBOX=/var/spool/mail/%u but when I try that I cannot map mail folders that reside under ~/mail. I have tried default_mail_env = maildir:~/mail:INBOX=/var/spool/mail/%u default_mail_env = mbox:~/mail:INBOX=/var/spool/mail/%u which is the setup i have now. I get this error when trying to connect via evolution error while scanning folders in "IMAP server localhost" imap command failed. invalid mask. when I use default_mail_env = maildir:~/mail:INBOX=/var/spool/mail/%u the error i get is: This store does not support subscriptions or they are not enabled. I have an Inbox Junk and Trash folder under that account. When I set up outlook as pop3 it says it connects fine but it doesn't download any mail. When I try to subscribe to folders via Outlook it says that it cannot connect.

[Dovecot] mbox slowness in dovecot-1.0-test61
by Todd Burroughs 28 Jan '05

28 Jan '05

Hi, We're trying out Dovecot to see if it's a good replacement for UW-imapd. It seems to be very slow in opening an mbox file, even after it's been indexed. (I mean way slower than UW) Here's some info on the system: Dovecot-1.0-test61 SuSE 8.1, Linux kernel 2.4 Using NFS to access mail. I've tried turning off mmap, using dotlocking, using fcntl locking (lockd, etc. are running), mbox_dirty_syncs and mbox_very_dirty_syncs. Also tried putting the cache files on local disk. Compile options where basically default. I'm accessing it with pine, using several filters which tend to do SEARCH commands. Has anyone come across this? Maybe I'm missing something obvious???

[Dovecot] Moving to Dovecot
by Matt Saunders 27 Jan '05

27 Jan '05

Hi there, I'm currently running IMAP with Courier and POP3 with Solid-POP3d. I'd like to migrate IMAP and POP3 to both use Dovecot. All this works fine in testing, except for the fact that I have two types of users for legacy reasons. One type of user has a Maildir-style inbox at ~/Maildir/ The other type has a mbox-style inbox at ~/Mailbox Is it possible to make Dovecot look for both? As far as I can see I'd need default_mail_env to accept multiple names, something like this: default_mail_env = maildir:~/Maildir/ mbox:~/Mailbox ...but it doesn't, so I'm stuck. :-( By default, Dovecot would work for me if I moved all my users' ~/Mailbox files to ~/mail/inbox but I really don't want to have to do that if at all possible as that'll break other custom stuff. Does anyone have any ideas? [ Apologies if this is a FAQ - I've had a good Google around and a look at the mail archives but can't find the info. ] TIA, Matt. -- Matt Saunders http://www.yoyo.org/matts/contacts/ "This is getting very silly.

[Dovecot] dovecot Maildir issue
by Tadghe Danu 26 Jan '05

26 Jan '05

I'm working on switching a domain from a Cyrus+postfix+procmail to Dovecot+postfix+procmail (using Maildir). It works great, except one small problem. I cannot figure out what the permissions for my Maildir directories should be. Can anyone point me to a doc or just a few pointers on what the permissions of the Maildirs should be? The only way I seem to be able to make this config work is to make the Maildirs world read+write. I can't exactly roll out a config like that :). I have postfix+procmail delivering to per user Maildirs under /var/mail. The permissions on /var/mail (pulled from the Wiki) are mail:/var/mail# ls -l /var/ |grep mail drwxrwxrwt 7 root mail 4096 Jan 25 22:37 mail The user Maildirs are set as: mail:/var/mail# ls -l /var/mail/ |grep tadghe drwxr-xrwt 2 tadghe tadghe 4096 Jan 25 22:36 tadghe When I try and access a mail box I get this in the logs an 25 22:35:34 mail imap(tadghe): opendir(/var/mail/tadghe/tmp) failed: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir() failed with file /var/mail/tadghe/new: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir() failed with file /var/mail/tadghe/new: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir(/var/mail/tadghe/tmp) failed: Permission denied Tadghe

[Dovecot] Trouble getting TLS to work
by Remy Zandwijk 24 Jan '05

24 Jan '05

Hi. I've Dovecot running on Solaris 9. Logging in without SSL or TLS works. Logging in with SSL (port 993) works. Logging in with TLS does not work. Tried Eudora, Thunderbird and Outlook Express, but none of them could log in. Outlook returns an error message like: "PLAIN authentication failed. None of the authentication methods supported by your IMAP server are supported on this computer.". Since SSL is working, I think I can savely say the SSL parameters are OK. My config includes the lines: disable_plaintext_auth = no auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam What could cause this problem?? Regards, Remy

Hi, I have a question about the raw logging feature. As I understand the documentation it is meant for traffic measuring. But it seems to be more targeted at developers. Is there a way for measuring the traffic for the end user? If not with raw loggin in another way?

[Dovecot] Experimental FreeBSD ports / packages for test61
by Dominic Marks 23 Jan '05

23 Jan '05

Hello, If anyone would like it I have provided a Dovecot 1.0 test61 port and package for FreeBSD 5.3 here. I made them for my own experimentation but thought they might be interesting to others I suppose. http://www.helenmarks.co.uk/~dom/dovecot/ These deviate from the stock test61 because I've updated and added a patch I wrote a long time ago for ioloop kqueue/kevent support in Dovecot. I have no configure skill at all so you get it even if you don't choose it in the options dialogue. It seems to work still, I tested it very lightly, but I don't use day to day, so YMMV. To use the shar file: gzip -d <path/to/dovecot.shar.gz> shar <path/to/dovecot.shar> cd dovecot make install To use the package: pkg_add -r http://www.helenmarks.co.uk/~dom/dovecot/dovecot-1.0-test61.tbz Cheers, -- Dominic

[Dovecot] Disallow creation of (sub) folders
by Remy Zandwijk 23 Jan '05

23 Jan '05

Hi. Is there a way to prevent users from creating new mailboxes? In our setup, we've several standard mailboxes (maildir format). Users should use these and only these. I allready tried to chown the base directory, e.g. /var/mailstore/r/remy/, to root, and delivery still works then, but procmail chown's this back to the users' name. I have a workaround by using symlinks, but I think this is a lame solution. Another question: when is Dovecot 1.0 supposed to be released for production purposes? Regards, Remy Zandwijk

[Dovecot] Strange behaviour with multiple auth channels
by Søren P. Skou 23 Jan '05

23 Jan '05

Hey all Just upgraded to Test-61 and at first everything looked like it worked without a hitch, I could log in and check mail (yay! ;-) ). Since I could log in, I never suspected anything would be amiss. Later one of my users told me he could no longer log in, regardless what he tried. Password error I thought and told him to go change his password, but then he explained he had not changed anything, and that his pop3 client just started complaining. Ok, time to go looking - I compared the dovecot.conf to the example from the tarball, nothing seemed as if it had changed. Then I started fiddling around to see if I could get any pattern. At that point I had two auth channels: auth default { mechanisms = plain userdb = sql /usr/local/etc/dovecot/sql.conf passdb = sql /usr/local/etc/dovecot/sql.conf user = mail } auth localuser { mechanisms = plain userdb = passwd home=/home/%u/Mail passdb = passwd home=/home/%u/Mail } Strangely enough I could see it connecting to the SQL database, I would have expected to see at least some queries when it checked for the user. But no. So I changed the configuration to: auth default { mechanisms = plain userdb = passwd home=/home/%u/Mail passdb = passwd home=/home/%u/Mail } auth virtualuser { mechanisms = plain userdb = sql /usr/local/etc/dovecot/sql.conf passdb = sql /usr/local/etc/dovecot/sql.conf user = mail } Lo and behold, my virtual users could log in - but now localusers could no longer. I've since then tried changing the auth default to auth localuser, but little does it do - I'm sort of out of my bounds here, everything works, but only if it is the second auth. The first channel seems to be ignored. So I tried adding more channels seeing what would happen. My current configuration looks like this: auth default { mechanisms = plain userdb = sql /usr/local/etc/dovecot/sql.conf passdb = sql /usr/local/etc/dovecot/sql.conf user = mail } auth localuser { mechanisms = plain userdb = passwd home=/home/%u/Mail passdb = passwd home=/home/%u/Mail } auth virtualuser { mechanisms = plain userdb = sql /usr/local/etc/dovecot/sql.conf passdb = sql /usr/local/etc/dovecot/sql.conf user = mail } As I suspected it grabs hold of localuser and uses that one. Any suggestions or "Well d'uh! you're missing...." would be welcome ;-) Friendly greetings S. P. Skou -- GPG Key: 8E58ACB3

[Dovecot] Evolution Slowness Fix
by Michael David Joy 22 Jan '05

22 Jan '05

Well, I seem to have tracked down what's going on with Evolution and Dovecot. It seems that Evolution has defaulted to checked for spam server side using Spamd on Fedora Core 3 without downloading the mail. It seems that spamd is the culprit in all this as it's trying to analyze pop3 mail without simply downloading all the new mail. I turned off the spam checking option in evolution and the crawling (read 5-10 min) email downloads stopped. I guess I should have noticed that this happened when I upgraded from Fedora Core 2 to 3, but we upgraded dovecot around the same time. While it still shouldn't be taking 10 min to download email (1 min a mail), at least I know what's going on now. Michael

[Dovecot] Kerberos/GSSAPI Auth Mechanism?
by John Waller 20 Jan '05

20 Jan '05

I have been reading that there may be a patch floating around to enable krb5 auth in dovecot <1.0, namely 0.99.10.8 (openbsd port). It could be I have something misconfigured, for openbsd supports kerberos and most programs which use the operating system's auth features use kerberos transparently through login(1). If there is a patch, I would be very interested in testing it. -- John Waller ganreshnu(a)gmail.com

[Dovecot] problems deleting folders
by Danny Sung 20 Jan '05

20 Jan '05

I've been having this problem for quite some time now of not being able to remove folders. I'm using: Fedora Core 2 dovecot-0.99.10.4-4 And dovecot is setup as using imaps (w/ SSL) and mbox files (instead of maildir). I've done a small amount of tracing to see what the problem is, and it looks like what happens is when all messages in a folder is removed, there's still a 0-byte file lying around. And the "delete" command issued from mail clients (I've used both Thunderbird and MS Outlook) end up trying to throw the file into Trash instead of somehow sending a delete command. This then results in an error. Maybe this is normal IMAP behavior, I don't know. But that's what looks like is happening. If anyone knows of a good solution to this, I would really appreciate it. I'd rather avoid using maildir but if anyone knows whether this will definitely solve the problem, then I'll make the switch. Thanks

[Dovecot] configure problem with MySQL 4
by Laurent Papier 19 Jan '05

19 Jan '05

Hi, the configure mysql detection doesn't work with MySQL 4.0.x from MySQL AB. Detail information: dovecot 0.99.13, MySQL-devel-4.0.21-0 from MySQL AB. ./configure --with-mysql ... checking for mysql_init in -lmysqlclient... no checking for mysql_init in -lmysqlclient... (cached) no This version of MySQL need to be linked with '-lz'. The configure script check for mysql both with and without '-lz' but the test result is cached ... so the test with -lz failed. The included patch helps me compiling dovecot (only check mysql with -lz). I know that this workaround is not a general solution. Full configure output and config.log available on demand. Execpting this problem, dovecot works fine for us (RedHat, MySQL auth, maildir). -- Laurent Papier - 03 88 75 80 50 Admin. systeme - Sdv Plurimedia - <http://www.sdv.fr/>

[Dovecot] Re: dovecot Digest, Vol 21, Issue 24: vacation messages
by Ted Knab 19 Jan '05

19 Jan '05

Normally, the vacation message works with the default mail server (MTA). In my case, I use the vacation program. Postfix delivers to the local mail user and if they have a .forward with the vacation info on it gets called. For a truly virtual setup that does not require unique uids on the filesystem there is gnarwl. Gnarwl is a program written in C that does vacation messages for virtual users. It works with Postfix, which is simplier that sendmail. :) >------------------------------ > >Message: 2 >Date: Thu, 13 Jan 2005 23:13:48 -0700 >From: "Del Stoliker" <dstoliker(a)alphagraphics.com> >Subject: [Dovecot] Virtual users vacation notices and forwards >To: <dovecot(a)dovecot.org> >Message-ID: <200501140613.j0E6DfZ9012233(a)smtp2.alphagraphics.com> >Content-Type: text/plain; charset="us-ascii" > >I'm in the process of moving from UW-IMAP to dovecot.

[Dovecot] 0.99.14-rc1
by Timo Sirainen 19 Jan '05

19 Jan '05

http://dovecot.org/rc/ Two backports from 1.0-tests and pretty important fix for mbox users if you're not already filtering X-UID header somewhere. For 1.0-tests you can fix it for now by applying patches http://dovecot.org/list/dovecot-cvs/2005-January/004046.html and http://dovecot.org/list/dovecot-cvs/2005-January/004047.html - Message address fields are now parsed differently, fixing some issues with spaces. Affects only clients which use FETCH ENVELOPE command. - Message MIME parser was somewhat broken with missing MIME boundaries - mbox: Don't allow X-UID headers in mails to override the UIDs we would otherwise set. Too large values can break clients and possibly Dovecot itself.

For FC2 and FC3. Users of MySQL and postgres should take note as the default build options have changed to remove these. The boot order has also changed to start dovecot after named, but this only takes effect if you run chkconfig to disable and re-enable the service and recreate the symlinks.

[Dovecot] Dovecot + Xmail Setup Howto
by Chris L. Franklin 17 Jan '05

17 Jan '05

OK I finally found time to write this. (this is for dovecot 99.X and Xmail 1.X >= 1.17) (in dovecot 1.0 it'll able to auth against Xmail via a auth script. aka You'll only need to have 1 user account databases, XMAIL's YAY !!!) Steps: 1. Install Dovecot. (rpm or Source) >From Source : http://wiki.dovecot.org/CompilingSource >From RPM : http://wiki.dovecot.org/PrebuiltBinaries 2. Edit config (my's listed below) CODE base_dir = /var/run/dovecot/ imap_listen = * pop3_listen = * info_log_path = /var/log/dovecot login_dir = /var/run/dovecot/login login = imap login_executable = /usr/libexec/dovecot/imap-login login = pop3 pop3_executable = /usr/libexec/dovecot/pop3 verbose_ssl = no default_mail_env = /var/MailRoot/domains/%d/%n/Maildir mail_cache_fields = Envelope MessagePart client_workarounds = outlook-idle mailbox_check_interval = 5 mailbox_idle_check_interval = 30 maildir_stat_dirs = no maildir_copy_with_hardlinks = no maildir_check_content_changes = yes auth_mechanisms = plain auth_userdb = static uid=97 gid=97 home=/var/MailRoot/domains/%d/%n/Maildir auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_passdb = passwd-file /var/MailRoot/dovecotusers.tab 3. Isnatll Xmail >From Source : http://www.xmailserver.org/Readme.html#build >From RPM : (rpm -i xmail-X.rpm) 4. Configure XMail, edit server.tab Server.tab Config: http://www.xmailserver.org/Readme.html#server_tab_variables Heres Mine (with in all xmail files there are no SPACES only TABS !!!) CODE "RootDomain" "nomadcf.com" "SmtpServerDomain" "nomadcf.com" "POP3Domain" "nomadcf.com" "HeloDomain" "nomadcf.com" "PostMaster" "postmaster(a)nomadcf.com" "ErrorsAdmin" "postmaster(a)nomadcf.com" "SMTP-MaxErrors" "0" "NoSenderBounce" "1" "RemoveSpoolErrors" "1" "NotifySendLogToSender" "1" "ReceivedHdrType" "1" "SmtpMsgIPBanSpammers" "Denied due to you being a F'in SPAMMER !!!!!"

Setup your XMail Domains + Users It's easy'st with a interface. Heres a list of some Windows : http://www.alouria.com/ Web : http://dev.waaf.net/xmail/ Web : http://www.akxak.de/xpai/ Web : https://sourceforge.net/projects/phpxmail 6. Give Dovecot permission to the domains dir under MailRoot I used acls to do this so that Xmail can still run as root and Dovecot could still run as a non-root user. (if you rather not do this your other option is tp run xmail as the same user a dovecot See non-Acls below) CODE setfact -R -m d:u:dovecot:rwx,d:g:dovecot:rwx;d:o:---,d:m:rwx /var/MailRoot/domains setfacl -R -m u:dovecot:rwx,g:dovecot:rwx;o:---,m:rwx /var/MailRoot/domains 7. Set Xmail to listen on another port then 110 for pop3. Add "-Pp 20110 " to xmail startup options. 8. Setup User Accounts. As of 99.X of dovecot it doesn't support using a external script to check user acount info (user/password). So it needs a place to have it's own useraccount storage place. For more ways dovecot can store user info see : http://wiki.dovecot.org/Authentication I use " passwd-file /var/MailRoot/dovecotusers.tab" and create it from a modified xmail2smapost script called xmail2dovecot. (See xmail2dovecot below) 9. Restart Xmail 10. Startup Dovecot Non-Acls: To allow Xmail to so it's thing + Allow dovecot Access to XMails MailRoot. You'll need to run Xmail as the user Dovecot runs at. I found after some trial and error that is pretty easy. What you'll need. 1. Iptables 2. su Setup 1. Disable Xmail from starting at boot. 2. Stop Xmail 3. edit the user dovecot and chnage there shell to /bin/bash 4. Create a IPtables rule to route port 25 to 20025 Example: CODE iptables -t nat -A PREROUTING -p tcp --dport 25 -j REDIRECT --to-port 20025 5. Change permissions in MailRoot from root.root to dovecot.dovecot CODE chown -R dovecot.dovecot * 6. Startup Xmail as so : CODE su - dovecot -c "/var/MailRoot/bin/XMail -Mr 24 -Pl -Ph -Sl -Ql -Yi 30 -Yl -Fl -Cl -Ll -PX 0 -Sp 20025 -Pp 20110 -Fp 20079 -Ms /var/MailRoot" XMail2Dovecot Script: This a script that was Org. used with smartpost. And was called xmail2smartpost.php But I changed it to output All the user account info into a simple passwd/Shadow. (user@domain:MD5-password) Download From : http://xmail.nomadcf.com/info.php?program=xmail2dovecot After Downloading it , extract it to the MailRoot/bin/ and then edit it. And lastly Run it as like so : CODE cd /var/MailRoot/bin/ ./xmail2dovecot.php > ../dovecotusers.tab -- Chris L. Franklin --

[Dovecot] Proposed dovecot update changes in Fedora
by Kenneth Porter 16 Jan '05

16 Jan '05

FYI, forwarded from the Fedora development list: ------------ Forwarded Message ------------ Date: Saturday, January 15, 2005 7:16 PM -1000 From: Warren Togami <wtogami(a)redhat.com> To: John Dennis <jdennis(a)redhat.com> Cc: Development discussions related to Fedora Core <fedora-devel-list(a)redhat.com> Subject: Proposed dovecot update changes John, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143707 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145214 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145241 Any objections to my proposed changes? I can implement all of this and supply patches for your review, or apply it myself to CVS if you wish. I summarize each problem and my proposed solution below. 1. Unnecessary dependency on mysql/postgresql ============================================= Prereq: postgresql Prereq: mysql These lines are wrong. The package is fine without it, because RPM auto-dep pulls in the client library of mysql and postgresql rather than a larger unnecessary chunk of those databases. These dependencies are resolved properly by yum and handled automatically. Solution: Just remove those lines. 2. dovecot.conf should default to fcntl locking =============================================== https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145214#c7 Our default dovecot.conf changed from fcntl to dotlock sometime after the release of FC2. That is one of the reasons why we see this above bug. This problem must now be attacked on two fronts: 1) Our default dovecot.conf must be changed to use fcntl by default again. If someone uses a broken NFS where fcntl doesn't work, then it is up them to edit their configuration to use dotlocks. If users have not modified dovecot.conf, then upgrading to the new package will set fcntl default. 2) For exisiting users who have modified dovecot.conf, it would be dangerous to force a change to fcntl during %post. Then "mail_extra_groups = mail" is the correct line to add durin 3. FC2 should not link to mysql/postgresql (???) ================================================ https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145241#c1 FC2 dovecot originally did not link to mysql and postgresql, so arguably we should not add those dependencies in an update. Unfortunately our current FC2 update is linked in this way, so we would be breaking existing users if they did begin using this functionality in FC2. I am guessing that the likelihood of this is very low and we should go ahead. (However we could just as easily leave it as is, then it would only be a minor annoyance rather than a real problem.) FC3 dovecot did link to mysql/postgresql libs, so we must not change that or split into sub-packages because then an update would break existing users. FC4 we have the option of splitting mysql/postgresql into sub-packages, which is probably the correct thing to do based on the php precedent. Thoughts?

dovecot: Jan 14 12:25:49 Error: IMAP(xxxuser): file istream-limit.c: line 85 (_seek): assertion failed: (v_offset <= lstream->v_size) That error message is generated when squirrelmail 1.4.4-rc1 attempts to access this peculiar message partially quoted below. It doesn't happen (after copying the message to our testing account) accessing it through squirrelmail now. But it did. The server is running test61 configured --without-pop3d --with-ssl=openssl and --disable-ipv6 and running on FreeBSD 5.2.1. I'm not sure if this bit of a message is useful, but I have seen that error message in dovecot's log more than just this once.

Some additional tests. I tried to add a test connection in the main.c under auth, which should be the main file of dovecot-auth.

[Dovecot] maildir and /var/spool/mail
by Steve Hickel 14 Jan '05

14 Jan '05

All, Not sure what to do next. Have imap working in that I can see messages in inbox. When I create a folder it won't create one. Looking at maillog shows that I don't have rights to folder /var/spool/mail/.sent or whatever folder I am trying to create. I have procmailrc and dovecot.conf point to /home/Maildir but for some reason something is tied to /var/spool/mail. Of course I am running FC3 and sendmail. Someone have any ideas as to what to try next? thanks in advance, Steve Hickel -- Steve Hickel <steve(a)korehicom.com> Kore/HiCom Corporation

[Dovecot] REQUEST: Different port(protocol) should be able to use a different certification.
by NAJIMA Hiroki 14 Jan '05

14 Jan '05

Hello, I want to use a different certificate for a different port(protocol). I searched http://wiki.dovecot.org/ and the mail archives. But such mechanism were not found. Could you implement a such mechanism? Or already implemented it, please teach how to do. I am assuming the following situations. MailAddress: [users](a)example.com SMTP Server: smtp.example.com POP3 Server: pop3.example.com IMAP Server: imap.example.com And pop3, imap, smtp are alias of real.example.com When use IMAPS, user connents imap.example.com POP3S, user connents pop3.example.com But one Certification file certificates only one FQDN. For example, dovecot.conf written that protocols = imaps pop3s ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # imap.example.com.cert.pem's CN is imap.example.com In this pattern. MUA such as Thunderbird warn when connect pop3s because FQDN is different. I have an simple idea in this problem. dovecot.conf protocols = imaps pop3s - ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem - ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # certification for imaps + imaps_ssl_cert_file = /etc/ssl/certs/imap.example.com.cert.pem + imaps_ssl_key_file = /etc/ssl/private/imap.example.com.key.pem # certification for pop3s + pop3s_ssl_cert_file = /etc/ssl/certs/pop3.example.com.cert.pem + pop3s_ssl_key_file = /etc/ssl/private/pop3.example.com.key.pem Dovecot uses imaps_ssl_cert/key whenever MUA connects imaps port, uses pop3s_ssl_cert/key whenever MUA connected dovecot's pop3s port. Could you discuss it? #If it was already discussed, please show pointer(URL) that discussion. Regards. ----- NAJIMA Hiroki

[Dovecot] Virtual users vacation notices and forwards
by Del Stoliker 14 Jan '05

14 Jan '05

I'm in the process of moving from UW-IMAP to dovecot. I'm exploring the idea of using virtual users with dovecot and storing all user information in LDAP. While bouncing this idea off of a coworker, he asked me how we could handle vacation notices and forwards. Currently, we're using a procmail recipe to generate the vacation notice, and the sendmail .forward file for forwards (although most of our forwarding takes place elsewhere so the .forward file is rarely used). These are, of course, dependant on the user having an account on the mail server. How are those of you using virtual users supporting this functionality? Thanks!

[Dovecot] Upgraded and authentication fails with LDAP

FreeBSD 5.2.1 Upgraded to dovecot 0.99.12.1 After authentication failed, I also upgraded OpenLDAP to 2.2.19 Dovecot and OpenLDAP are now the most recent versions in the ports.

[Dovecot] Test 57 -> Test 60
by Andrew Hutchings 13 Jan '05

13 Jan '05

I just tried upgrading one of our mail cluster servers to test60 from test57. We have dovecot connecting to 3 different MySQL tables in 3 sql conf files. The error seems to stem from this: Jan 13 14:57:59 svr21 dovecot: auth(sql8): file auth-client-connection.c: line 31 (auth_client_send): assertion failed: (conn->refcount > 1) After this the auth process gets killed with signal 6. The sql8 is the config in use at the time, but can be any of the 3. I take it this is the auth process not liking the 3 auth lookups (refcount > 1)?

[Dovecot] Dovecot create mbox files. But why?
by Mirko Schulze 13 Jan '05

13 Jan '05

Hi there, my dovecot is now running normaly, but there is a small problem.... We want to to use the maildir format at the mailstorage. But the imap part of dovecot creates the for mbox specific files, but why? I created a passwd-file for a testuser. At this tme, there is only on line: test2@dev2.abc.de:ujAN28k8.5zV2:99:99:*:*:*:* in dovecot.conf are these interesting lines: auth_userdb = static uid=99 gid=99 home=/vrmd/pop3imap/links2mailboxes/%u/Maildir auth_passdb = passwd-file /vrmd/mailin/conf/pop3imapdb.passdb.txt I think, if a path ends of /Maildir dovecot will autodetect the maildir format. So what is wrong? Regards Mirko

[Dovecot] using separate authentication based on protocol

Hi, I've got a problem of authenticating users when they've got the % character in their login name. It always returns -ERR Authentication failed. I've done some tests (explained below). 1. the mysql answer to SELECT password FROM users WHERE uid = 'foo%domain.com' is 123 2. the mysql answer to SELECT password FROM users WHERE uid = 'foo(a)domain.com' is 123 3. with a password_query like this : password_query = SELECT password FROM users WHERE uid = '%u' it works fine with foo(a)domain.com but not with foo%domain.com 4. everybody can login with password 123 with a password_query like this : password_query = SELECT password FROM users WHERE uid = 'foo%domain.com' => I don't know what's done with the % character when passed to the %u variable. Can somebody enlight me ? Thanks a lot.

[Dovecot] link() failed / maildir_copy_with_hardlinks=no / maildir-save.c.patch
by David C. Reeve 12 Jan '05

12 Jan '05

Hi, I have recently been having a small problem with Dovecot (dovecot-0.99.13) not honouring the "maildir_copy_with_hardlinks" config option, specifically when it is set to "no". This results in errors to the syslog looking like: Jan 12 09:59:21 imap imap(dave): link(/afs/.../tmp/1105541958.P1137Q0M41428.imap, /afs/.../new/1105541958.P1137Q0M41428.imap:2,S) failed in maildir_copy: Invalid cross-device link The supplied patch will, when maildir_copy_with_hardlinks=no, rename files inside maildir's instead of hard linking them, hence honouring the configuration option. A word of caution! This all relies on the filenames in maildir being unique (which they should be, and this shouldn't be a problem, but..). It is possible (although unlikely) that renaming the file could destroy a file in the target directory; no checking is done to assure this is not the case! (If you are paranoid you can always write another patch). Yes I am using AFS (openafs specifically) to hold my maildir's, which does not support hard links. However AFS assures that rename operations are atomic so we can use that instead (this may be the case for other filling systems that do not allow hard links). Hope that helps some one else ;) Dave -- David C. Reeve <David.Reeve(a)pnsol.com> Predictable Network Solutions

[Dovecot] 1.0-test60
by Timo Sirainen 11 Jan '05

11 Jan '05

http://dovecot.org/test/ I've been running this for two hours now without problems. I guess it's pretty stable. - Keyword support finally included. Not too well tested, but I couldn't get it to break. Doesn't store the keywords into maildir/mbox yet. Hopefully soon. - Major reorganization of code in dovecot-auth, and not yet finished. Load balancing between multiple auth procsses (ie. auth_count > 1) was before done by connecting to each one's socket separately. Now there's a single socket which a balancer process listens to and distributes the requests to worker processes. What's left to do is make a single auth process support handling multiple auth sections in config file. This makes it possible to: - have ordering-sensitive fallbacking for multiple passdbs - have fallbacking work with non-plaintext authentication - allow for all kinds of new great features more easily. For example we could add PAM-like "required" vs. "sufficient" selection for auth sections, or some rules when each passdb is used (eg. based on username, domain or IP range). After that it should also be easy to run dovecot-auth standalone because it would read its own config file. I'm also planning on making it compatible with Postfix's master process, so you could directly add it to master.cf (actually I think I only have to move one fd from 3 to 6 and it'd work). - Added "passdb" userdb. Basically means that the passdb already returned all the information needed for userdb. With SQL this means you could do: SELECT password, uid AS userdb_uid, gid AS userdb_gid, home AS userdb_home FROM ... - If authentication failed because of some internal error, tell it to client instead of showing a generic "Authentication failed." error. - MySQL driver supports load balancing between multiple servers. Just add a new host=xx to connect string. It's not currently supported to have different usernames/passwords. Probably not worth it? - rawlog code rewritten. Should work better. - If userdb returns non-numeric UID or GID, look it up from passwd/group. - Rewritten message address parser. The old code could have lost some spaces and might have even returned invalid MIME string because of it. This affected only clients which use FETCH ENVELOPE command. - mbox: If lines began with NUL characters, things broke. Also fixed another potential problem with parsing mboxes. As a result hopefully these fix a problem with expunge sometimes leaving a few extra characters to beginning of mbox. - Added mail_debug setting which logs where and how Dovecot is trying to locate mails. Helpful when initially figuring out why Dovecot isn't working right. auth_debug=yes now also logs all SQL queries and LDAP lookups and some other things. - etc.

[Dovecot] IMAP crashes with signal 10 (SIGBUS)

Subsequent versions still crashed and I looked into the problem further. Specifically it crashes at this line offset = *((const uint64_t *)data); when "data" assumes a non-64 bit aligned value. At first I thought that 64-bit ints should always be aligned on 64-bit boundaries, but when I isolated this code into a standalone executable to demonstrate it (no arguments to cause a crash, one argument is OK): int main (int argc, char *argv[]) { int a[]={1,2,3,4}; long long int i64; void *p=(void *) (&a[argc]);; printf("Pointer to 32-bit int = %x\n",p); i64 = *((long long int *)p); printf("Successful casting to 64-bit int: value=%016llx\n",i64); } I found out that the presence of any optimisation (-O, -O2, -O3) will cause this to crash, yet it will work if no optimisation is present even though a pointer being cast is still not aligned on a 64-bit boundary (but aligned on a 32-bit boundary). I check the gcc bug web page page came up with this reference which may explain this behaviour. http://gcc.gnu.org/bugs.html#known - see section "Casting does not work as expected when optimization is turned on" http://mail-index.netbsd.org/tech-kern/2003/08/11/0001.html They claim that this casting violates ISO aliasing rules and the results like crashing are to be expected. Maybe this statement ought to be rewritten memcpy(&offset,data,sizeof(uint64_t)); There is one other statement at mbox-synbc.c:319 (1.0-test59) that may need this consideration.

[Dovecot] ldap auth (with user and domain a different places)
by Timo Boettcher 11 Jan '05

11 Jan '05

Hi, I am trying to use dovecot with my virtual-hosting setup. I have all users in LDAP like uid=user,dc=domain.tld,o=myorganization for the user with the mail-address user(a)domain.tld. This is also the username that user should use for login, but it is nowhere in the ldap-db in this form together, just user and domain at their own places. Is it possible to authenticate with dovecot against such an ldap-directory? After reading docs and comments in the config-file, I think no, but I am not sure. As I read the source, it is not possible just now, but would be, if I could use %d in the searchbase. Or did I understand something wrong? TIA Timo Boettcher

[Dovecot] dovecot + vpopmail
by Chris L. Franklin 10 Jan '05

10 Jan '05

I was just wondering how dovecot interacts with vpopmail. Does it just call the vchkpw and pass the username and password to it then wait for a it to tell dovecot weather the user is vaild or not ? Does vchkpw pass back the users homedir ? PS. My plan is to just replace vchkpw with a script/program of own. that dovecot can call to auth a user again xmail passwd file. And using "auth_passdb = static uid=<uid> gid=<gid> home=<dir template> mail=<dir template>" to fill in all the holes. -- Chris L. Franklin --

Debian unstable, x86 # dovecot --version 0.99.12 # tail /var/log/mail.log ... Jan 6 16:56:55 gecko dovecot: child 16505 (imap) killed with signal 11 ... When I use squirrelmail, the imap process always segfaults when I try to enter my INBOX group. Squirrelmail produces the following error message: ERROR : Connection dropped by imap-server.

Hello all I am using Freebsd 4.10stable, postfix 2.1.5 with SASL and TLS, procmail version 3.22 and binc IMAP 1.2.8 binc uses IMAPdir style mail boxes, Spam assassin, and ClamAV. Wish to convert to dovecot but your program does not support IMAPdir does it??? also i have many user accounts that i wish to use untouched if possible. I guess this is a migration question for the most part i am switching to dovecot because of its ability to use postgre database files and real log file.

[Dovecot] Where are flags stored?

Hello, I don't now wheather this is IMAP or actually dovecot-specific, but I hope you people here knows about this at least: Where are flags like seen/unseen or e.g. message-priority stored? My goal is to mark spam or other filtered by procmail as "seen", so that dovecot doesn't notify MUAs about new mail in IDLE mode. Are there any mail-headers, so I can set these with procmail to accomplish that? Thanks for help, A

[Dovecot] Repair/Cleaup Maildir
by Glen Eustace 10 Jan '05

10 Jan '05

After having fought an issue with Courier-imap on FC3 for a week (that is still unresolved), I decided to try Dovecot instead. So far, fingers crossed, the issue has not re-occured. Migrating from courier-imap/sqwebmail to Dovecot/Squirrelmail was reasonably painless but I now have an problem. Is there a utility available to cleanup/repair the maildir tree for each user ? As part of the migration, I copied all of the courierimapsubscribed files to .subscriptions and removed the leading 'INBOX'. This seemed to be enough to get things going. Unfortunately, people who had only ever used webmail didn't have a courierimapsubscribed file. When they next used squirrelmail, a new .subscriptions file was created but didn't contain their folders. I tried to fix this by recreating the subscriptions file for each user and adding in all the .directories in their maildir root. I now have a maildir hierarchy with lots of crud in it. I need a utility to go through and deleted all the files that shouldn't be there anymore and to ensure that the subscriptions files are correct. Does such a utility exist ? If not, can anyone tell me where I can find a good description of what Dovecot expects to find in maildirs so I can write one myself. Any suggestions/help appreciated. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen and Rosanne Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.

[Dovecot] Extremely Slow Pop3 Downloads, Evolution 2.0.2
by Michael Joy 10 Jan '05

10 Jan '05

Hello All, We've been running Dovecot for imap for quite some time and have had little trouble with it. However, we recently switched over to using dovecot for pop3 because of simplicity as well as security issues with the older UW based pop server. I've noticed one serious problem. The only client that seems to have any issue at all with the server is Evolution. In pop3 mode, it takes a minute or more to download a few messages on an inbox with 400+ saved messages in it over gigabit ethernet. Over a DSL connection using MS Outlook 2k3 it takes about a minute total for all messages. Similarly with KMail it takes about 5-10 seconds to download all messages in the pop3 box. The messages trickle in with evolution 2.x, I've tried 2.0.0, 2.0.1, and 2.0.2 and all have this problem. I haven't tried the 1.x series as I don't have any linux boxes that old available to test. So apparently, there's two things of concern. 1. The server is definitely fast enough to handle the large mail box. 2. There's some serious incompatibility in Evolution/Dovecot causing for the 14.4 modem email download speeds over lan. We're running Dovecot 0.99.12 on Debian unstable, however 0.99.11 exhibited this behavior as well. If anyone has some hints, I'd greatly appreciate it. It's annoying having to wait 5-10 min to download mail in the morning when one gets into work ;) If there's any other information I can provide, please ask. Thanks to whichever kind soul finds time to trudge through this problem with us. Michael D. Joy HEP - University of Mississippi mdjoy(a)phy.olemiss.edu

[Dovecot] Cannot access a file with Mulberry from a dovecot server if the mail does not end with a newline character.
by Sven Kirmess 07 Jan '05

07 Jan '05

I use Mulberry 3.1.6 on Windows to read my mails with dovecot 0.99.12 Solaris 9. There are some mail which I cannot read. When I try to open such a mail, dovecot quits and restarts (I can see that with ps, nothing is logged). The Mulberry log just looks like this: | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00009 FETCH 695 (BODY.PEEK[1]) | * 695 FETCH (BODY[1] {61} | | --> #7.2300 Sun Dec 19 12:59:33 2004 | * OK dovecot ready. | | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00001 CAPABILITY | * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE AUTH=PLAIN | A00001 OK Capability completed Looks like it just restarts the connection. The interesting thing is, that I can access the file with Netscape 4.8 via dovecot. The problem is the following: I copied the file in the Maildir directory, opened the copied file with vi and saved it. Now, I run a diff: | $ diff orig:2,S copy:2,S | Warning: missing newline at end of file orig:2,S | 12c12 | < <http://forums.mtgnews.com/attachment.php?attachmentid=35559> | --- | > <http://forums.mtgnews.com/attachment.php?attachmentid=35559> As you can see, vi adds the newline on the last line automatically if you save the file. Now, Mulberry/dovecot is able to read this file. I'm not sure if this is a dovecot or Mulberry problem. btw: This problematic mail was created with Mulberry 3.1.6. ;-) Sven

[Dovecot] Using Dovecot with Thunderbird 1.0 on Macintosh

Hi.. (and Happy New Year).. I tried switching over from Apple's Mail client (applemail) that is part of Panther to using Thunderbird 1.0 and find that all of the folders in my imap mailbox are messed up. Below is what Thunderbird is claiming the folder structure looks like : Inbox Arch Archiv Archive BMW Co E-Bay M Miscellaneous ML Bargains CKF Que Sof Sonn Ideally, the way it looks in Applemail looks more like the following: Inbox Archive BMW CarFax Coupons E-Bay Miscellaneous ML Bargains CKF [and a bunch of others that were missing from Thunderbird] Nextel OpexLD Palm Paypal Quest SW Realtors Registrations+Purchases Schoolpop ... [others] Software Updates Sonnet ... [others] Any ideas on what is going on here? I just moved to DoveCot 0.99.12, but it doesn't appear to make any distance. Also, if I try to pull up any of the weird folders in Thunderbird, it of course complains about the folders not existing.. Any ideas on how to get around this would be much appreciated!

[Dovecot] possible bug with mail->get_header and caching?
by Johannes Berg 06 Jan '05

06 Jan '05

I don't know if this is intended or not, but here it comes. I have * that copy plugin I was working on * dovecot 1.0-test59 * thunderbird test client My copy plugin looks for the X-DSPAM-Signature header line, and reports it to syslog as such: imap: we have a signature: "X-DSPAM-Signature: <sig>" where <sig> is replaced by what is found in the header line. This only happens when I copy in/out of the SPAM folder (which works fine). Now, when a mail is copied from INBOX to SPAM that doesn't have the signature line, I return an error to the client saying the user can't do that copy since the signature line is necessary. I detect the condition of not having that signature line by checking like this: if (!(signature = mail->get_header(mail, "X-DSPAM-Signature")) { ... return error ... } This works fine, error comes back. Second try, copying a mail that has the header line: works. So, lets do some code changes, disconnect and reconnect to reload the plugin. All of a sudden, copying mails that don't have the header line works too! Uhh? Lets go looking at syslog: imap: we have a signature: "X-DSPAM-Signature: " The only rational explanation I could come up with is that dovecot caches the header line and somehow decided that since it knows about the X-DSPAM-Signature header line mails that don't contain it should have an empty version of it. Well, I can of course test for this (and I actually should anyway, an empty signature isn't useful to dspam), but I do think this is a bug since it makes distinguishing between empty and non-present header lines impossible.

[Dovecot] PostgreSQL user database
by Marco Herrn 06 Jan '05

06 Jan '05

Hi, I am using postgresql for my password and user databases. The problem is, that the information needed in the user database is held in more than one table. But it seems to me that dovecot expects to get all the information for mailbox, uid, gid and home in _one_ query. Is there a way to get around this?

[Dovecot] Dovecot + MySql (NO PAM) Howto
by Roi Efrati 06 Jan '05

06 Jan '05

As mentioned before, I got Dovecot with Fedora and it does not have the necessary documentation. Can some one please direct me to the correct path of making this type of configuration work. I got Dovecot to authorize the users Via PAM & Mysql but still getting errors (acct_mgmt & setcred) that I can't figure out how to solve.

[Dovecot] virtual hosting
by Tom Allison 06 Jan '05

06 Jan '05

I'm trying to figure out how I might set up some virtual hosting accounts for my server. domain1 would be delivered via procmail to ~/Maildir mail directories domain2 would be delivered via postfix to /var/mail/vhosts/domain2/username and similarly for additional domains. There's also one domain that's delivered to another machine, but that's not a dovecot issue. I just mention it for completeness. currently I have only domain1 and only: default_mail_env = maildir:~/Maildir I'm not really sure how to set this up for additional locations of maildir:/var/mail/vhosts/%d/%n/Maildir (This seems right?) Right now I'm wondering if I have to do one of the following: create two instances of dovecot with seperate configuration files? move everything to /var/mail/vhosts/%d/%n/Maildir data structure and the rewrite all my local (~/Maildir) procmail rules to manage delivery.. This is seeming sticky?

[Dovecot] why dovecot try to access the uses's home?
by Farkas Levente 06 Jan '05

06 Jan '05

hi, after i try to use dovecot with ldap i configure dovecot as: ------------------------ first_valid_uid = 499 last_valid_uid = 499 first_valid_gid = 499 last_valid_gid = 499 default_mail_env = maildir:/home/mail/%d/%n auth_userdb = static uid=499 gid=499 home=/home/users/%d/%n auth_passdb = ldap /etc/dovecot-ldap.conf ------------------------ but after this i've got the error in imap.log: ------------------------ dovecot: Dec 29 14:39:14 Fatal: chdir(/home/users/<username>) failed with uid 499: Permission denied ------------------------ i see the reason since each user has it's own uid and uid 499 can't access to the users home which has 0700 access right. but why dovecot would like to access the user's home? does it nessesary? since in this case one static uid can be usable or this uid has to be read (write?) access to all user's home. is there any usage of static uid in this case? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] 0.99.1[12] IMAP problems with Apple Mail.app?
by Jim Tittsler 06 Jan '05

06 Jan '05

Is anyone else having trouble using the Apple OS X Mail.app with a Dovecot IMAP server? With 0.99.11 and 0.99.12 attempting to read certain messages using IMAP or IMAPS seems to put Mail.app into spinning pizza of death mode. Sniffing the connection, it looks like it happens after the client issues a BODY.PEEK[] and the server has responded with the (UID XXXX BODY[] {YYYY}...) and OK Fetch completed. I've only been able to catch it happening with messages that are either (a) Base64 encoded or (b) those that claim to be multi-part/alternative, but only seem to contain a single part. The client acts like it has received the message, since if I kill Mail.app and restart it, I am able to read the problem message from its cache. Is this a Mail.app bug? Is it something about the way Dovecot is responding to the BODY.PEEK[] in these cases? Using Mail.app with the Novell myrealbox.com IMAP I haven't seen problem, even with a test problematic message I redirected there, although admittedly I'm changing the headers by doing the redirection. I haven't gotten 0.99.13rc3 to get past the autotools stage of complaining about AM_ICONV (and a number of AC_ warnings), so I've yet to try it.

I have a question regarding dovecot (1.0-test52) and pop3. I have users that do not have home directories, they only have an inbox in /var/mail. When they try to pop their email, dovecot tries to create ~/mail and then fails. Is there a way around this or will all email users need to have a home directory?

v0.99.13 2005-01-06 Timo Sirainen <tss(a)iki.fi> * GNUTLS support hasn't been working for a while, so it's not even tried to be used anymore unless explicitly wanted. + Added CRAM-MD5 authentication mechanism. Patch by Joshua Goodall + Added SMD5 and LDAP-MD5 password schemes and changed MD5 scheme to use LDAP-MD5 if the password isn't in MD5crypt format. Patch by Joshua Goodall + Workaround for some POP3 client bugs: if message doesn't contain the "end of headers" empty line, add it automatically. + vpopmail supports now all password schemes, most importantly MD5crypt works now without support from libc's crypt() - SQL and LDAP authentication was broken - SEARCH UNKEYWORD wasn't working

[Dovecot] authenticate authenticated users
by Tzafrir Cohen 05 Jan '05

05 Jan '05

Hi I'm using dovecot on a LAN server. I sometimes read mail from the server itself locally with mutt and sometimes remotely with mutt or mozilla . I would like to avoid typing my password whenever necessary but without writing a plain-text equivalent copy of it locally. It feels quite silly to have to type the password locally becase the imapd does not know that the process is indeed a process of the user tzafrir. It has all the information it neeeds to check that. wu-imapd has something called "pre-authentication": the imapd is run by the user unpriviliged to access mail in the user's home directory. As a bonus this works quite nicely with ssh public key authentication. I know that at least mutt and pine support running a custom command for creating an imap connection. But then again, wu-imapd is built quite, well, differently. Any ideas? -- Tzafrir

Test58 and test59 breaks "compact folders" and "expunge" in thunderbird and evolution. Messages marked for deletion just sit there as if compacting folders or expunging have no effect. Thunderbird continues to behave erratically with dovecot test builds. I haven't been able to test the imap_client_workarounds=tb-negative-fetch option yet as I'm still running test52. Thunderbird displays blank messages when they are opened, but "Edit as new" shows the message contents.

[Dovecot] PLAIN-MD5 passwords?
by Peter Clark 03 Jan '05

03 Jan '05

After I found out that {CRYPT} doesn't support passwords longer than 8 characters, I decided to switch over to MD5 for user passwords in my LDAP database. However, while I have no problem with Postfix + SASL, Dovecot fails to authenticate. Relevant bits from /etc/dovecot-ldap.conf: user_attrs = mailAddress,,,,, # The search string is identical to what's found in /etc/saslauthd.conf: user_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) pass_attrs = mailAddress,userPassword pass_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) default_pass_scheme = PLAIN-MD5 When I try to connect using either KMail or SquirrelMail (which worked just fine before I switched schemes), the following error appears in /var/log/syslog: ldap(user(a)mydomain.tld): password mismatch But when I try 'testsaslauthd -u user(a)mydomain.tld -p longpassword' it authenticates just fine. I have the line 'password-hash {MD5}' in /etc/ldap/slapd.conf, and I used 'slappasswd -h {MD5}' to create the MD5 versions of the passwords. Dovecot is v. 0.99.11. If I can't figure out how to get it to work with MD5, I guess I'll have to go back to CRYPT, but it would be nice to have longer passwords... :Peter

[Dovecot] Wanted: gnutls11 support
by Jaldhar H. Vyas 03 Jan '05

03 Jan '05

I talked to Timo about this before and even provided the beginnings of a patch but don't have enough time to really do a proper job. Anyway, dovecot doesn't work with recent versions of the GNU TLS library. As a result, I compile the Debian package with OpenSSL. However some of the other libraries used, such as OpenLDAP are linked against GNU TLS so Dovecot is linked against both. And it is suspected this is leading to bugs. So could some kind soul provide Timo with a patch he can include in 0.99.13? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[Dovecot] SASL AUTH
by Tom Allison 02 Jan '05

02 Jan '05

I'm reading through the dovecot wiki pages for virtual hosting with postgresql/postfix/dovecot/debian and it looks pretty nice but I think I'm going to skip the SASL authentication since I'm in a trusted network. I think all I need to do is skip section 5 entirely and bypass all the sasl references in the postfix section. Technically, I don't think any of the SASL has much to do with the dovecot configuration.

[Dovecot] random pool depletion
by Johannes Berg 31 Dec '04

31 Dec '04

I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it really necessary to use random numbers from /dev/urandom for temporary filenames? And even if, couldn't it use less? It apparently uses 8 bytes every time. johannes

[Dovecot] Authentication difficulties
by Timo Sirainen 30 Dec '04

30 Dec '04

There are constantly pretty basic questions in this list (and in my inbox) about how to get user authentication work correctly. This means that the documentation how it all works is either bad, or people don't find it easily. Any ideas how to improve it? I did this now: - Documentation link in dovecot.org now points directly to Wiki, so people don't go read the outdated documents - Upcoming 1.0-tests and 0.99.13 will contain doc/USE-WIKI-INSTEAD file pointing to Wiki: http://dovecot.org/list/dovecot-cvs/2004-December/003928.html - Updated comments in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003924.html - Added pointers to Wiki in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003927.html How good are the Wiki documents about user authentication in general? The content should probably be split somehow to "getting started" vs. "everything there is to know about it" and "system users" vs. "virtual users". I'm not really sure how to best do that though. I think the Wiki in general could be better organized. Wish I knew how.

I have set up a directory (/var/local/virtualdir/) as the maildir with a special user/group (virtualmail) and in it I create directories for each domain (example1.tld, example2.tld etc) and sub dir's for each mailbox). Only at the moment, apart from the first one, they are all created as with user root as the owner. How important is to have all the directory tree owned by the same user group (virtualmail:virtualmail) ?

hi, it takes me another hour do debug it again, although i already report it for both joshua and timo. the original patch for openldap's md5 crypt has a small bug. in passdb-ldap.c the schema is already PLAIN-MD5 since that was set in the other part of the original patch in password-scheme.c. do anybody use dovecot with ldap and md5 password? i don't think so:-( this patch would be useful to apply before the final 0.99.13. anyway in the current 1.0 series the PLAIN-MD5 and LDAP-MD5 schema are different. at least plain_md5_verify and plain_md5_generate differ from ldap_md5_verify and ldap_md5_generate. why? -- Levente "Si vis pacem para bellum!" --- dovecot-0.99.13/src/auth/passdb-ldap.c.lfarkas 2004-12-22 17:06:25.000000000 +0100 +++ dovecot-0.99.13/src/auth/passdb-ldap.c 2004-12-22 17:06:56.000000000 +0100 @@ -109,12 +109,11 @@ } /* Special case for OpenLDAP's MD5 type */ - if (strcasecmp(scheme, "MD5") == 0) { + if (strcasecmp(scheme, "PLAIN-MD5") == 0) { buf = buffer_create_static(data_stack_pool, 16); if (base64_decode(password, strlen(password), NULL, buf) == 1 && buffer_get_used_size(buf) == 16) { password = binary_to_hex(buffer_get_data(buf, NULL), 16); - scheme = "PLAIN-MD5"; } }

[Dovecot] Deleting a message through IMAP
by Doug Eubanks 28 Dec '04

28 Dec '04

I have been having a problem with the test releases...I am now using Test 59. When I delete a message using SquirrelMail (IMAP) the message stays in the message list....but you can't open it anymore because it can't be found, if I logout and log back in...the message is gone from the list. I thought it could be a problem with the cache, so I added mail_never_cache_fields = MessagePart Envelope Body only to recieve Dec 24 09:23:34 news dovecot: IMAP(admin): mail_never_cache_fields: Invalid cache field name 'Body', ignoring Any ideas? This problem has plagued me for a while and I always go back to using the and older test like 22 and the problem isn't there... Doug
