[Dovecot] auth_user setting?
by Joseba Torre 21 Feb '07

21 Feb '07

Hi all, I've installed rc23 in a new testing machine, and i've had some permission problems related to dovecot-master.conf. As I have my master passwords in that file, I don't want it to be world readable. dovecot -n shows that auth_user is nobody, so setting the permissions to nobody.whatever 640 solves the problem. Anyway, I've tried to change the auth_user setting with no effect. Is it configurable? Aaaaaaaaaagur. -- Joseba Torre. CIDIR Bizkaia.

[Dovecot] Possible Bug in quota-fs.c
by Martin Konopka 20 Feb '07

20 Feb '07

Hi, I'm using filesystem quotas with dovecot 1.0rc22 on my Linux 2.4.27 box. The quota limit gets correctly reported in kilobytes to the client but the amount of used space is reported in megabytes. In quota-fs.c I noticed that only the currently used space is divided by 1024: Line 241: *value_r = dqblk.dqb_curblocks / 1024; *limit_r = dqblk.dqb_bsoftlimit; After removing /1024 everything works fine. regards, Martin

[Dovecot] Convert plugin
by Jay Chandler 20 Feb '07

20 Feb '07

convert_mail = mbox:%h/mail Convert plugin. If set, specifies the source storage path which is converted to destination storage (mail_location) when the user logs in. The existing mail directory is renamed to <dir>-converted. I'm not entirely clear on what this does. If someone can clarify for me, I'll update the Wiki. I'm hoping it'll allow me to convert from mbox to Maildir-- otherwise I'm looking at a weekend of downtime when that project comes due... -- Jay Chandler Network Administrator, Chapman University 714.628.7249 / chandler(a)chapman.edu Today's Excuse: high pressure system failure

[Dovecot] Reading mail for Virtual and Real LDAP Users
by Aaron Luchko 20 Feb '07

20 Feb '07

I'm trying to setup a system with ldap+postfix+dovecot. Everyone who gets an email is stored in LDAP, some of these users also have a local unix account, regardless I want all users to be dealt with as virtual users. All the mail is stored by postfix in /var/spool/mail in Maildir format with permissions 600 vmail:vmail. Everything works fine when dovecot tries to read the mail of a completely virtual user, the problem is when dovecot tries to read mail for a user who has an account on the machine, dovecot finds the user's local account, then it tries to read the mail as that user. Even if first_valid_{u,g}id is low enough to allow login the user still doesn't have sufficient permissions to read the mail. I can't figure out why this is happening and was hoping someone could help me out. thanks, Aaron /etc/dovecot-ldap.conf: hosts = server.example.com base = dc=example,dc=com dn = cn=Directory Manager dnpass = password uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { }

[Dovecot] NTLM oddities
by Cassidy B. Larson 20 Feb '07

20 Feb '07

Started implementing the MasterUser changes to my config files so I can finally offer SPA for pop3/imap. Things are working fine with the MasterUser (horray!), however one of my guys started using SPA with Outlook Express and started getting another users mailbox. Turns out to be related to NTLM. His Outlook express is configured for the username of 'johnsmith'. However, you'll see the NTLM took the username from his XP machine login, it appears, which is just "John". However, what is really weird, is the "failed" on the "client out" line, but then the proxy went ahead and proxied to the storage server. Here's some output from debuggage: dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client in: AUTH 1 NTLM service=POP3 lip=204.17.177.60 rip=209.33.215.142 resp= dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client out: CONT 1 dovecot: Feb 19 16:15:56 Info: auth-worker(mail.infowest.com): sql(John, 209.33.215.142): query: SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)),'*masteruser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'masterpass' AS pass FROM iwmailsystem.virtmailbox AS v INNER JOIN iwmailsystem.popserversAS p ON ( p.storeIP = '204.17.177.60') INNER JOIN authenticate.users AS a ON (a.userID= IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@', p.host))) WHERE v.userID = IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)) AND v.client_active=1; dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): password(John, 209.33.215.142): Credentials: 8447128CC04AD05D1CD15F0C2F17F136 dovecot: Feb 19 16:15:57 Info: auth(mail.infowest.com): client out: FAIL 1 user=John host=204.17.177.76 destuser= john(a)host.com*masteruser nologin proxy pass=masterpass dovecot: Feb 19 16:15:57 Info: pop3-login: proxy(John): started proxying to 204.17.177.76:110: user=<John>, method=NTLM, rip=209.33.215.142, lip= 204.17.177.60 Questions: 1) So is it possible to use OE for SPA authentication without it sending the "XP username", but the actual account username OE is configured for ? 2) Why, when it "FAIL"ed did it still proxy? This seems bad :) Thanks, Cassidy

[Dovecot] relocating indexes.
by Rob Shepherd 20 Feb '07

20 Feb '07

Dear Dovecot users, I'd like to relocate indexes from NFS to local storage. I plan to replace... default_mail_env = maildir:~/.maildir with mail_location = maildir:~/.maildir:INDEX=/usr/local/var/dovecot/index/%u However, to minimise disruption, by avoiding dovecot rebuilding indexes for many user's large and numerous folders, I'd like to copy the existing indexes to the new location. Here is a list of _my_ indexes (in and under ~/.maildir) ./.Drafts/dovecot-uidlist ./.Drafts/dovecot.index ./.Drafts/dovecot.index.cache ./.Drafts/dovecot.index.log ./.OpenLDAP/dovecot-keywords ./.OpenLDAP/dovecot-uidlist ./.OpenLDAP/dovecot.index ./.OpenLDAP/dovecot.index.cache ./.OpenLDAP/dovecot.index.log ./.OpenLDAP/dovecot.index.log.2 ./.Sent/dovecot-keywords ./.Sent/dovecot-uidlist ./.Sent/dovecot.index ./.Sent/dovecot.index.cache ./.Sent/dovecot.index.log ./.Trash/dovecot-keywords ./.Trash/dovecot-uidlist ./.Trash/dovecot.index ./.Trash/dovecot.index.cache ./.Trash/dovecot.index.log ./.mailscanner/dovecot-keywords ./.mailscanner/dovecot-uidlist ./.mailscanner/dovecot.index ./.mailscanner/dovecot.index.cache ./.mailscanner/dovecot.index.log ./.mailscanner/dovecot.index.log.2 ./.nagios/dovecot-keywords ./.nagios/dovecot-uidlist ./.nagios/dovecot.index ./.nagios/dovecot.index.cache ./.nagios/dovecot.index.log ./.samba/dovecot-keywords ./.samba/dovecot-uidlist ./.samba/dovecot.index ./.samba/dovecot.index.cache ./.samba/dovecot.index.log ./.samba/dovecot.index.log.2 ./.sw-announce/dovecot.index ./.sw-announce/dovecot.index.cache ./.sw-announce/dovecot.index.log ./dovecot-keywords ./dovecot-uidlist ./dovecot.index ./dovecot.index.cache ./dovecot.index.log ./dovecot.index.log.2 Would I be correct in copying these to /usr/local/var/dovecot/index/rob/ (_my_ new index loc) whilst preserving the structure of the folders etc. Thanks Rob -- Rob

Hi all, I recently installed Dovecot rc22 from the FreeBSD ports and I have some problem with the dovecot startup: - If I start dovecot manually, it works fine, it starts and I get messages in /var/log/maillog - If I reboot the machine, that's where the problem appears, dovecot doesn't seem to start and I get nothing, no errors in /var/log/maillog Any idea if this is a known problem and how to fix it ? Thanks in advance, Regards, -- Alexis

[Dovecot] Run fetchmail after login?
by Brett B. 20 Feb '07

20 Feb '07

Hello all, I was wondering if it is possible to run fetchmail after a user logs into dovecot? So far I have tried to make a small script that contains the command for fetchmail. Then I told the dovecot mail_executable to look at that script. However this ends up leaving the server hanging and does not seem to work. Thanks

[Dovecot] Dovecot losing .mailboxlist files
by Lauri Jesmin 20 Feb '07

20 Feb '07

Hello! I am running a site that has two servers, 10 000 users in both, Solaris 9 and home directories with mbox mailboxes shared with NFS. Indexes are kept separately in both server, on local disks, both servers are serving imap (from NFS mboxes). We are trying to convert from uw-imap to dovecot. Servers are currently running on their limits and now i have mysterious problems with .mailboxlist file: i patched dovecot to use .mailboxlist file instead of .subscriptions, but sometimes the .mailboxlist file disappears on some users. Instead there are appearing .nfsXXXXXX files, where XXXXXX is combination of numbers and capital letters. Also some users have problems with subscribing to folders, others do not have this problem. It seems to be that users who do not have .mailboxlist have also problems with subscribing to folders. Dovecot is version 1.0rc22. I have not discovered error messages in logs. -- Lauri Jesmin <lauri.jesmin(a)ut.ee> Tartu Ülikool

[Dovecot] Weird Issues with latest nightly (pre-rc23)
by Cassidy B. Larson 20 Feb '07

20 Feb '07

Just updated one of my proxy boxes to the latest nightly (20070217), restarted the dovecot process and got a bit of errors showing up for each pop3/imap connection. Feb 19 11:14:00 marbella dovecot: pop3-login: Login: user=<user1(a)host.com>, method=PLAIN, rip=209.33.217.218, lip=204.17.177.60 Feb 19 11:14:00 marbella dovecot: POP3(user1(a)host.com): Set pop3_uidl_format in config file Feb 19 11:14:00 marbella dovecot: child 33684 (pop3) returned error 89 Feb 19 11:14:04 marbella dovecot: imap-login: Login: user=<user2(a)host.com>, method=PLAIN, rip=204.17.177.50, lip=204.17.177.60 Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): mbox: Can't create root mail directory /dev/null/mail: Not a directory Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): MAIL environment missing and autodetection failed (home /dev/null) Feb 19 11:14:04 marbella dovecot: child 33753 (imap) returned error 89 On the pop3 errors above. Why should I have a pop3_uidl_format in the config file for the proxy? This was working fine on rc19. I do have a pop3_uidl_format on my storage boxes. Same with the imap section. It should just proxy over (and is on rc19), the proxy shouldnt have to know about the mail directory. Am I the only one seeing this? Or have I missed a config change that is required? thanks, Cassidy

[Dovecot] LDAP auth load? (looking for advice)
by Troy Engel 19 Feb '07

19 Feb '07

One of the changes my beta testers are testing is switching from NIS to LDAP for login/auth/homedir lookups; all is working perfectly, Dovecot + PAM/nss_ldap is A-OK. No issues here, we've been using LDAP lookups on other servers for years. I'm wondering about load, specifically if when I switch the entire company over, will the new authentication load stress my LDAP server to the point of breaking. A) Does anyone here have some numbers or experience in this switch that could lend some real-world advice? We're talking maybe... 50 people with large (numerically, not gig-age) mailboxes, and ThunderBird seems to open 4-5 connections per client based on the logs. B) Would anyone advise that I run a slapd slave directly on the main Dovecot server to alleviate load? Is this overkill and I shouldn't worry about it? Mainly what has me concerned is that on the Dovecot machine, I'm getting a number of entries in the messages that look like: dovecot-auth: nss_ldap: reconnecting to LDAP server... dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) No failures ever, it all just works. But still this tickles my brain that maybe it'll need more robustness come production time. Thanks for your feedback, -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 19 Feb '07

19 Feb '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem?

[Dovecot] wrong dovecot GID while upgrading
by Zbigniew Szalbot 18 Feb '07

18 Feb '07

Hello, I tried to upgrade dovecot from 1.0.rc7 to rc22 but I got this error at the end of the upgrade process: Dovecot has reserved the groupname 'dovecot' and gid '143': ERROR: groupname 'dovecot' already in use by gid '1003' Please resolve these issues and try again: Either remove the conflicting group or if you wish to continue using a legacy gr oup override DOVECOT_GID. *** Error code 1 Stop in /usr/ports/mail/dovecot. So I went to /usr/ports/mail/dovecot and edited the Makefile to change the GID into: DOVECOT_UID?= 1003 DOVECOT_GID?= 1003 SCRIPT_ENV+= DOVECOT_UID=${DOVECOT_UID} \ DOVECOT_GID=${DOVECOT_GID} I saved the makefile and ran portupgrade again but I got stopped by exactly the same error. I'd appreciate suggestions how to resolve this. Thank you! -- Zbigniew Szalbot

[Dovecot] Reproducible duplicate messages bug with Mail.app+Dovecot
by Andrew Moran 18 Feb '07

18 Feb '07

Hey guys, I am not sure if this is a Mail.app bug or a dovecot bug. I can reproduce it 100% of the time using dovecot and Mail.app. I cannot reproduce it with other imap clients, which at first made me think it was Mail.app, but then I tried Mail.app with other imap servers and couldn't reproduce it either, so it's definitely the combination of the two. So I thought I'd try you guys first before submitting a bug to Apple. The problem: If I move multiple messages (set "A") from one imap folder to another, then delete those messages, and then move another set into that same folder (set "B"), then all the messages in set B show up as duplicates until I relaunch Mail.app. My configuration: Server: Dovecot 1.0rc22 using Maildir on FreeBSD 6.1 Client: Mail.app 2.1 on OS X 10.4.8 Steps to reproduce: (these steps involve trashing messages, so it's best to test this on email you are going to toss anyway) 1) Create a new imap folder (let's say "bar") 2) Drag more than one message (let's say 3 or 4) from existing imap folder "foo" to new folder "bar". 3) Click on new folder "bar" and see messages in there. 4) Select messages and delete them (Delete key). Messages are gone as expected. 5) Go back to original folder "foo" and drag a few more messages into new folder "bar" 6) Click on bar. 7) You will notice that all the second set of messages show up twice. Relaunching Mail.app at this point makes the problem disappear. I'm guessing this has something to do with the deleted messages from Set A being purged until the close of imap connection. Any help narrowing this down would be appreciated. Thank you, --Andy

[Dovecot] Problem moving emails with attachments or HTML links
by J. Wren Hunt 18 Feb '07

18 Feb '07

I recently switched from UW-IMAP to Dovecot (1.0.rc15 on Ubuntu) and am experiencing a weird problem that I haven't been able to figure out yet: If I try to move a message from one IMAP folder to another, all works fine if the message is plain text. However, *sometimes* the message will not be transferred if it contains either an attachment and/or an HTML link (operation times-out). Not all the time, but just enough to be annoying. I've looked through the logs and for settings in the .conf file and can't find anything obvious that I've overlooked. Can anyone help me with any parameters that might be causing this type of problem? Thanks so much! Wren Hunt Cambridge, MA

[Dovecot] Dovecot "open files" (again?)
by falz 17 Feb '07

17 Feb '07

I'm a new dovecot user, just began using it last week. I switched from courier because my research showed that Dovecot did indexes, and allows me to store them anywhere I chose. I did this, and it fixed some severe disk IO issues that my server had. (25k horde only webmail install using imap proxy). I'm using quotas, and by default had it set to 'dirsize'. my postfix is already creating 'maildirsize' files, so I opted to change dovecot to use this instead. However, when I do, I run into the "too many open files" issue that's been reported many times on the list. I've seen a lot of mention of too many open files, but I haven't seen it related to the quota type used. It's possible that simply my using 'dirsize' as the quota type slows things down enough to not have the issue? I don't really know. Anyhow. I doubled my max open files in FreeBSD's /boot/loader.conf to: kern.maxfiles="24656", but to no avail. When I have it set to maildirsize, the open files on the system grows uncontrollably. Under normal use, it's somewhere below 5k: sysctl -a | grep openfiles kern.openfiles: 4415 I looked into the patch mentioned here: - http://www.dovecot.org/list/dovecot/2006-November/017536.html - http://dovecot.org/list/dovecot-cvs/2006-November/006776.html Those patches already appear to be in rc15, which I'm already running (Via FreeBSD's ports). I also applied the patch mentioned here awhile back: - http://www.dovecot.org/list/dovecot/2005-June/007647.html and rebuilt, but it didn't help out either. There are also freebsd specific notes on forcing a limit on dovecot itsself using login.conf, but that wouldnt really fix anything, it would just cause dovecot to not interfere with other running daemons. - http://www.mail-archive.com/ports@openbsd.org/msg08646.html Any thoughts? TSS, you mention a few times in these notes that you're unable to reproduce this. Perhaps try with the maildir as quota? More details about my setup: - FreeBSD 4.8 (yea, I know) - Imapproxy (http://www.imapproxy.org/) - Postfix to create maildir++ maildirsize folders - MySQL backend The work of this is spread out between several servers, dovecot is running on the server that's the final SMTP delivery location, and has local disks with the maildirs. --falz

[Dovecot] Problem/workaround with X-Keywords and Apple's Mail.app
by Joey Coleman 17 Feb '07

17 Feb '07

Hello, I've just switched from UW-IMAP to Dovecot, and for the most part, things are good. However, I encountered the problem with the X-Keywords header not being written back into individual messages in an mbox file (originally described in [1], and Timo gave a clue as to maybe why in [2]). What was happening for me is that Apple's Mail.app would flag a message as spam, which happily sets a couple keywords in the message, but those weren't being written back (at least, I didn't see them in the file on the server). The "DO NOT DELETE..." message had a perfectly fine X-IMAP header, and up until I switched things were working great. The user visible symptom of this happened every time new spam arrived in my Junk folder [3] --- the new spam would arrive, be flagged as spam by Mail.app, and the earlier pieces of mail would promptly be unflagged! Anyway, Timo's clue in [2] prompted me to turn off both mbox_lazy_writes and mbox_dirty_syncs (the latter just on the off- chance... it's a low-volume server, so I can deal with the inefficiency). Lo and behold, Mail.app started acting sane again *and* the X-Keywords header appeared immediately. Oddly, during all of this, the Status and X-UID keywords would appear in the messages just fine; no clue as to why those and not X- Keywords. Version details are: - Dovecot 1.0rc13 [4] - FreeBSD 5.3-RELEASE - Apple Mail.app 2.1 (752/752.2) cheers, --joey [1] http://dovecot.org/list/dovecot/2006-March/011872.html [2] http://dovecot.org/list/dovecot/2006-June/014126.html [3] And it felt really strange while troubleshooting this as I found myself *hoping* for another piece of spam to arrive. Bleh. [4] Yes, two versions behind current, but in my defense, I did check the announcements and they didn't seem to mention the problem.

[Dovecot] again... cross compiling
by Martin Höfling 17 Feb '07

> Create a cache file with the right values, or call configure with those > values set in the environment. OK, i ran configure with -C one time without cross compiler env set, to obtain the variables another time with -C to use the config.cache . I could not find anything related to the check whether size_t is signed. I found a variable which i set that way: ignored_signed_size=${ignore_signed_size=1} What's wrong with that? Cheers Martin P.S.: Is there a way to obtain all variables in an easy way, or to obtain the variable that has to be set by hand? -- Frag' nicht - Du könntest eine Antwort erhalten.

Since deliberate choice is required to go in and set the maillist option, this is no different than if I configure my MUA to set the reply-to header on messages I send to the list. So the way it has been implemented for this list is not a problem at all. If people feel the need to reply to me off list, I feel that should be a deliberate choice on their part. -- Kenny Dail <kend(a)amigo.net>

[Dovecot] filtering out LIST cruft?
by Dan Price 17 Feb '07

17 Feb '07

In planning our migration, I've noticed that lots of users have bits of lint in their ~/mail and/or ~/Mail. For example-- for an mbox called "blah" we may see: blah blah.msf (from Thunderbird) .blah.summary (from... I'm not sure, dtmail maybe) .blah_SIMS_index0003 (from our old IMAP server). When the user goes to "subscribe" they are often overloaded with too many items to choose from-- because all of these files are selectable in the UI-- LIST happily returns them. Is there a way to get dovecot to skip over these, by regex? Could it optionally "taste" files to see if they look like mboxes? I looked at the wiki and the source but didn't find anything. In the absence of this feature, I wonder how other sites have handled this? Obviously I can do some cleanup during migration, but I find that those pesky msf files like to come back. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] severe performance problem (mail cache related?)
by Dan Price 17 Feb '07

17 Feb '07

Hi all, we're having a bad day with email :) I have a user who was complaining of poor performance today when opening mailboxes. Total time to open the box was about 1 minute. Upon truss'ing the imap process during an open, I saw the trace quoted below at the end of the email. As you can see, for each "FETCH" line of response, we were seeing dovecot do a ton of work-- mmaping anon, lots of munmaps(), etc. -- mmap() and munmap() are not free. The stack trace of at least one of the munmaps is captured below, as well-- deep inside of the mail caching code. Then, I moved aside the user's .imap directory, assuming that forcing dovecot to rebuild its indices and caches could help-- and sure enough the user reported that mailbox open times had dropped to 18 seconds. I truss'd that open, briefly, and it was just a ton of preads at high speed. So I don't know why this user was fine for a week, then suddenly hit this. This is a grave concern if I'm going to roll this out from 15 test users to 250 production users. Thanks for your help.

by Robert Schetterer 16 Feb '07

16 Feb '07

Hi @ll, with dovecot latest following http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL i have defined plugin { quota = maildir acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/dovecot-trash.conf } Example dovecot-trash.conf file 1 Spam 2 Trash 3 Sent from wiki The Trash plugin. When saving a message would make user go over quota, this plugin automatically deletes the oldest mails from configured mailboxes until the message can be saved within quota limits. this dont work at my setup where quota is coming out of sql is there any trick to solve this? or did i missunderstand something -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by Jim Garrison 16 Feb '07

16 Feb '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file. I'm using postfix as the MTA.

[Dovecot] Proxy with MasterUser + Authentication issues
by Cassidy B. Larson 16 Feb '07

16 Feb '07

Per Timo's direction, I decided to give the MasterUser a try in connecting my proxy to my destination server. This might allow for the use of 'secure password' for my clients that like to check that box by default. A couple of problems I'm running into running RC15: #1: My Proxy's SQL password_query line: password_query = SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = '%u' and v.imap_active = 1 I'm wanting to authenticate the user on the proxy before I send it off via the MasterUser to the destination server. However, I show this in the logs: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= x.y.z.a rip=a.b.c.d resp=AGJ1dGNoQGluZm93ZXN0LmNvbQBzZWNyZXQ= Info: auth-worker(default): sql(user(a)host.com,a.b.c.d): query: SELECT a.clearpass wd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS p roxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth(default): file auth-request.c: line 207 (auth_request_save_cache): assertion failed: (extra_fields == NULL || (strstr(extra_fields, "\tpass=") == NULL && strncmp(extra_fields, "pass=", 5) != 0)) Error: child 54122 (auth) killed with signal 6 The Wiki showed I should return a 'pass' column. However, that's choking the query up in auth-request.c. Could it be the "\tpass" from auth-request.c? If I change user(a)host.com's password to 'someass' and remove the 'pass' column from the password_query, it authenticates, and proxy's over just fine. Am I doing something wrong? I want to authenticate the user locally on the proxy and pass off the 'master password' to the proxy, but using 'pass' doesnt work. 'password' column does. Doesnt help me though for my situation :) Problem #2: I'm wanting to put the masteruser/pass in the database for quick retrieval and updating. So I setup dovecot.conf as: passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf master=yes #pass=yes } passdb passwd { } and dovecot-sql.conf with: password_query = SELECT '%u' AS user, 'master-password' AS password Trying to connect locally with a "telnet localhost 143" via: 1 login user(a)host.com*someuser "somepass" Give me this in the detail log file: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= a.b.c.d rip=w.x.y.z resp=AGJ1dGNoQGluZm93ZXN0LmNvbSphZG1pbkBpbmZvd2VzdC5jb20AbWFzdGVyLXBhc3N3b3Jk Error: auth-worker(default): BUG: PASSV had invalid passdb ID Warning: Killed with signal 15 I am able to successfully authenticate with the master user/pass if I store it in a passdb file. However, I'd prefer to have it in the database for obvious reasons. Any help to the above would be appreciated. thanks, Cassidy

[Dovecot] Dovecot proxy question (hostname instead of ip)
by Wouter de Jong 16 Feb '07

16 Feb '07

Hello, We are planning to use the Proxy feature of Dovecot, but fail to implement it currently the way we would like to. Reason is that proxy insists to have an IP-address as host : Feb 15 15:43:24 proxy-test.widexs.nl dovecot: pop3-login: proxy(username): mspool01-test.widexs.nl is not a valid IP When I changed the query to force the IP-address of the above server, it works. Would it be possible to make this work, but more important ... Are there any reasons NOT to make this work ? :)) Kind regards, Wouter. -- WideXS http://www.widexs.nl Wouter de Jong System-Administrator Tel +31 (0)23 5698070 Fax +31 (0)23 5698099 Bijlmermeerstraat 62, 2131 HG HOOFDDORP, NL

[Dovecot] domain truncated
by Nemanja Miletic 16 Feb '07

16 Feb '07

Hi all, I have a problem with domain information being truncated from username during ldap search, so it can not be used in mail_location. This happens when user part of the username %n is used in pass_filter in passdb ldap search. When I use %u all username information remains and mailbox can be located. Here is my configuration. In dovecot.conf I have two locations one for system and one for virtual users: ... mail_location = maildir:/var/spool/mail/%n mail_location = maildir:/var/spool/mail/vdom/%d/%n ... Also two configurations for passdb: ... passdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap-virt.conf } ... Here info is searched in ldap: /etc/dovecot-ldap-virt.conf ... base = dc=%d,ou=Virtual Domains,dc=eunet,dc=yu pass_filter = (&(objectClass=posixAccount)(uid=%n)) ... And the line in log file stating that maildir can not be located: mkdir(/var/spool/mail/vdom//cone/cur) failed: Permission denied Is this a bug or I am doing something wrong. Thank You, Nemanja

I'm not sure if this is related or not, but we set mmap_disable=yes last week and since then have seen what appears to be an occasional infinite loops.

There is no error logged in the dovecot log when this occurs, and it only stops by "kill -9" on the process... # top -c PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 7832 virtual 25 0 580 496 376 R 71.5 0.0 70:59 0 imap [user(a)example.com 192.168.1.14] # lsof -p 7832 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME imap 7832 virtual cwd DIR 147,0 600 2372995 /data1/mail/ex/example.com/us/user imap 7832 virtual rtd DIR 3,3 4096 2 / imap 7832 virtual txt REG 3,3 412996 789553 /usr/libexec/dovecot/imap imap 7832 virtual mem REG 3,3 33856 771355 /usr/lib/dovecot/lib10_quota_plugin.so imap 7832 virtual mem REG 3,3 7720 771364 /usr/lib/dovecot/imap/lib11_imap_quota_plugin.so imap 7832 virtual mem REG 3,3 106912 278626 /lib/ld-2.3.2.so imap 7832 virtual mem REG 3,3 14868 278653 /lib/libdl-2.3.2.so imap 7832 virtual mem REG 3,3 1571824 278633 /lib/tls/libc-2.3.2.so imap 7832 virtual 0u IPv4 -1140164370 TCP vip.mail17a.r4.iad.mlsrvr.com:imap->director2.r2.iad.emailsrvr.com:56195 (ESTABLISHED) imap 7832 virtual 1u IPv4 -1140164370 TCP vip.mail17a.r4.iad.mlsrvr.com:imap->director2.r2.iad.emailsrvr.com:56195 (ESTABLISHED) imap 7832 virtual 2w FIFO 0,5 3154802927 pipe imap 7832 virtual 3r CHR 1,9 599160 /dev/urandom imap 7832 virtual 4r FIFO 0,5 3154802928 pipe imap 7832 virtual 5w FIFO 0,5 3154802928 pipe imap 7832 virtual 6r FIFO 0,5 3154802929 pipe imap 7832 virtual 7w FIFO 0,5 3154802929 pipe imap 7832 virtual 8u REG 22,1 11112 6602923 /var/index/data1/mail/ex/example.com/us/user/.Elementos enviados/dovecot.index imap 7832 virtual 9u REG 22,1 50824 6602903 /var/index/data1/mail/ex/example.com/us/user/.Elementos enviados/dovecot.index.log imap 7832 virtual 10u REG 147,0 3074 6346008 /data1/mail/ex/example.com/us/user/maildirsize imap 7832 virtual 11w REG 147,0 905650 7062984 /data1/mail/ex/example.com/us/user/.Elementos enviados/tmp/1171483586.P7832Q0M770594.mail17a.r4.iad.mlsrvr.com # strace -p 7832 read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable)
