[Dovecot] dovecot 1.0rc6 and LDAP problem
by Marcin Deranek 16 Aug '06

Hi, I have been using Dovecot with LDAP support (only for password authentication) for a couple of weeks already and everything was running smoothly so far.. till last week when discovered interesting thing: whenever I start LDAP server (openldap 2.3.24) before I start Dovecot everything is fine.. however when Dovecot is started first and then LDAP server it's not possible to authenticate :-( My dovecot-ldap.conf file: hosts = 127.0.0.1 auth_bind = yes auth_bind_userdn = uid=%u,ou=Users,dc=domain,dc=tld ldap_version = 3 base = ou=Users,dc=domain,dc=tld These are messages I get in syslog: slapd is down Aug 15 18:56:55 ftp dovecot: Dovecot v1.0.rc6 starting up Aug 15 18:56:56 ftp dovecot: auth(default): LDAP: Can't connect to server: 127.0.0.1 slapd is started Aug 15 18:58:36 ftp dovecot: imap-login: Disconnected: Inactivity: method=plain, rip=192.168.1.3, lip=192.168.1.2, TLS Aug 15 18:58:36 ftp dovecot: login: tried to change state 2 -> 2 (if you can't login at all, see src/lib/fdpass.c) slapd messages: Aug 15 18:57:19 ftp slapd[20544]: slapd starting Aug 15 18:57:36 ftp slapd[20544]: conn=0 fd=11 ACCEPT from IP=127.0.0.1:37703 (IP=0.0.0.0:389) Aug 15 18:57:36 ftp slapd[20544]: conn=0 op=0 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" method=128 Aug 15 18:57:36 ftp slapd[20544]: conn=0 op=0 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" mech=SIMPLE ssf=0 Aug 15 18:57:36 ftp slapd[20544]: conn=0 op=0 RESULT tag=97 err=0 text= Aug 15 18:58:39 ftp slapd[20544]: conn=0 op=1 BIND anonymous mech=implicit ssf=0 Aug 15 18:58:39 ftp slapd[20544]: conn=0 op=1 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" method=128 Aug 15 18:58:39 ftp slapd[20544]: conn=0 op=1 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" mech=SIMPLE ssf=0 Aug 15 18:58:39 ftp slapd[20544]: conn=0 op=1 RESULT tag=97 err=0 text= Aug 15 18:59:41 ftp slapd[20544]: conn=0 op=2 BIND anonymous mech=implicit ssf=0 Aug 15 18:59:41 ftp slapd[20544]: conn=0 op=2 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" method=128 Aug 15 18:59:41 ftp slapd[20544]: conn=0 op=2 BIND dn="uid=user,ou=Users,dc=domain,dc=tld" mech=SIMPLE ssf=0 Aug 15 18:59:41 ftp slapd[20544]: conn=0 op=2 RESULT tag=97 err=0 text= Has anyone else has the same problem ?

[Dovecot] stale imap processes with 1.0.rc6 on FreeBSD
by Jeremy C. Reed 16 Aug '06

16 Aug '06

Was running dovecot-1.0.rc2 but many stale imap processes (only one user of IMAP). Switched to dovecot-1.0.rc6 but problem continued. This is on FreeBSD 4 something. Maybe it has bug with kqueue?? I read messages about the stale imap processes on the list. It seems to hit *BSD systems. But email about new release candidate indicated it should be fixed. I read on the pkgsrc commit list about --with-ioloop=best So I configured with that and saw that the I/O loop method is now kqueue. (I saved configure output and it was poll before). But the stale imap processes problem continues. For one user over past couple hours I have eight imap processes in "I" state. I have: File offsets ........................ : 64bit I/O loop method ..................... : kqueue File change notification method ..... : kqueue Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file pam checkpassword (modules) Building with SQL drivers ............: And I have: protocols = imap pop3 protocol imap { imap_client_workarounds = outlook-idle delay-newmail } (Just started using delay-newmail today.) My maillogs don't show any problems. The IMAP user tells me that Outlook says it has reset connections often. I see multiple imap-login Login within a few minutes for this same user who said received a connection reset in outlook at the same time. Just received a screenshot that said: Microsoft Office Outlook Failed to update headers. The TCP/IP connection unexpectedly terminated by the server. Then also received an error (in Outlook I think), like: imap session idle too long, connection reset (I don't have or use Outlook myself so can't test myself.) It is used for a lot of pop3 and seems fine with that. (It uses stunnel for pop3s but not imaps for over a week to eliminate stunnel from our troubleshooting). Any ideas on troubleshooting this would be appreciated. Jeremy C. Reed

[Dovecot] cleartext password logging
by Imre Gergely 16 Aug '06

16 Aug '06

hi is it possible to somehow log cleartext passwords (preferably after the authentication is done, and the user logged in)? 'auth_verbose = yes' doesn't seem to be enough. i have dovecot 0.99. thx.

[Dovecot] Dovecot - Issue with Maildir++ quotas
by Andrew Richards 16 Aug '06

16 Aug '06

Hi, I've been bitten by an issue running Squirrelmail on top of Dovecot using Maildir++ quotas. Having configured these quotas in Dovecot, I notice that Dovecot appears not to exclude the 'Trash' folder from its quota calculation (which it should do, according to the Maildir++ spec). Unfortunately this breaks Squirrelmail if I try to delete a message from a close-to-quota mailbox - as per July's thread: "Maildir++ quota - how to handle a full mailbox" Which unfortunately means that a fairly full mailbox can become 'Wedged' with Dovecot/Squirrelmail in this situation with its owner unable to delete messages if that's the only way they access their mailbox. I took a look at the source and found the 'Quota exceeded' lines in src/plugins/quota/quota-storage.c but didn't understand it well enough to dive in... except to notice that the 'Trash' folder doesn't appear to get excluded from the calculations. cheers, Andrew.

[Dovecot] multiple Authentication
by Marc Perkel 16 Aug '06

16 Aug '06

I'm using the following authentication passing the full email address user(a)domain.com auth default { mechanisms = plain # Linuxconf passwd-like file with specified location passdb passwd-file { args = /etc/vmail/shadow.%d } # Linuxconf passwd-like file with specified location userdb passwd-file { args = /etc/vmail/passwd.%d } user = root } But - what I want to do is if the user doesn't enter the domain part I want it to assume one specific domain. How would I do that?

[Dovecot] POP3 and TLS don't work (dovecot 1.0 rc6)
by kaspars.bogdanovs＠awtech.lv 16 Aug '06

Hi! It seems there are problem with POP3 connection when TLS enabled. Previously it worked fine, but for now it doesn't... Plain & SSL POP3 works. Plain, TLS & SSL IMAP works too. In logs nothing than: dovecot: Aug 16 10:36:23 Warning: pop3-login: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac [xxx.xxx.xxx.xx] xxx.. - remote ip address On client side: KMail - Could not connect to host Your POP3 server claims to support TLS but negotiation was unsuccessful. You can disable TSL in KDE using the crypto settings module. Thunderbird (on Windows) - nothing special, but can't connect. OS: Debian Linux __ Kaspars P.S. sorry for bad english

[Dovecot] default_realm problem
by Anton Martchukov 16 Aug '06

16 Aug '06

Hello List, I've upgraded to dovecot from FreeBSD ports, changed the config from previous 0.99 version, but meet a problem with %d variable beeing empty in userdb static configuration directive. Our server supports multiple domains, e.g. 'mxc.ru' and 'mail.mxc.ru'. Users can log into using their full e-mail address like antonm(a)mxc.ru or antonm(a)mail.mxc.ru, but the feature of adding default domain should also be present, e.g. when logging with user name 'antonm' server should assume username to be 'antonm(a)mxc.ru' cause 'mxc.ru' is the default domain. This wroked fine in 0.99 version, but, alas, I can't get it working in newer version. I've tried different settings combination, but all of them results in '%d' beeing empty Debug authentication log is: dovecot: Aug 16 10:59:46 Info: auth(default): auth(antonm(a)mxc.ru,10.3.1.192): username changed antonm(a)mxc.ru -> antonm dovecot: Aug 16 10:59:46 Info: auth(default): ldap(antonm,10.3.1.192): uid(user)=antonm userPassword(password)=<hidden> dovecot: Aug 16 10:59:46 Info: auth(default): client out: OK 1 user=antonm dovecot: Aug 16 10:59:46 Info: auth(default): master in: REQUEST 11 97887 1 dovecot: Aug 16 10:59:46 Info: auth(default): master out: USER 11 antonm uid=1004 gid=1004 home=/data/mai lspool//antonm The problem here seems to be with "username changed antonm(a)mxc.ru -> antonm", but I do not know how to switch it off. The relevant config file parts are: dovecot.conf: auth_default_realm = mxc.ru auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth default { mechanisms = plain digest-md5 passdb ldap { args = /usr/local/etc/dovecot-ldap.conf } userdb static { args = uid=1004 gid=1004 mail=maildir:/data/mailspool/%d/%n } } dovecot-ldap.conf: #all user attrs here are commented, since we don't get any user info from ldap, but checking a password #user_attrs = uid,homeDirectory,,,uidNumber,gidNumber #user_attrs = ,,,,,,, #user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_filter = (&(objectClass=mailUser)(dc=%d)(uid=%n)(accountActive=TRUE)) default_pass_scheme = PLAIN The authentication is working, so on the pass_filter in dovecot-ldap.conf '%d' is resolved properly, but in userdb static's mail argument it's empty whatever I do. Thank you for your help! -- Anton Martchukov - http://www.martchukov.com

[Dovecot] Problems after upgrade (0.99.x -> 1.0.x)
by fazer69＠o2.pl 16 Aug '06

16 Aug '06

Hello :) I had a working Dovecot 0.99.x with the following dovecot.conf: ### ssl_disable = yes disable_plaintext_auth = no login = imap verbose_proctitle = yes default_mail_env = maildir:%h/Maildir auth = default auth_mechanisms = plain auth_userdb = passwd /etc/passwd auth_passdb = shadow /etc/shadow auth_user = root protocols = imap pop3 ### Then I've downloaded, compiled and installed Doveot 1.0.rc6, I tried lot of "possibilities" in the new dovecot.conf but I always get : dovecot: Dovecot v1.0.rc6 starting up dovecot: Login process died too early - shutting down dovecot: child 15288 (login) killed with signal 11 dovecot: child 15289 (login) killed with signal 11 dovecot: child 15290 (login) killed with signal 11 Some add. info: # dovecot -n # /usr/local/etc/dovecot.conf ssl_disable: yes login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login auth default: passdb: driver: shadow args: /etc/shadow userdb: driver: passwd How can I get the new Dovecot acting as the old one? I don't use pam (which seems to be default now), simply shadow passwords (Slackware). http://wiki.dovecot.org/UpgradingDovecot did not help me. TIA, websafe

[Dovecot] Migrating from qpopper to dovecot
by asko 16 Aug '06

16 Aug '06

Hi, I am planning a migration from Qpopper 4.0.5 to Dovecot.. I need to use mbox format (because Openwebmail does not have native Maildir support yet) and pop3. The system will have about 1500 users, once migrating is complete. To avoid users downloading their mailboxes all over again, i need to set "pop3_reuse_xuidl = yes".. But that option works since Dovecot 1.0alpha1. RHEL has latest stable version 0.99.11-2. So let me rephrase my question: is latest dovecot (1.0.rc6) stable enough to handle the load (mbox with pop3) or should I wait for the stable version to come out.. I want to avoid trouble under heavy load and/or with different pop3 clients. I found some problem reports of mbox related issues from dovecot mailing list. I could go with latest Qpopper 4.0.8, trading speed to safety.. If you have any similar experiences, please share your knowledge ;-) -- asko

[Dovecot] LDAP Authorising users from Active Directory
by Rob Coward 16 Aug '06

16 Aug '06

Hi, I am having stability problems setting up dovecot to authenticate virtual users against Active Directory on Win2k3. If the correct userid and password are used, everything works fine, see first logfile snippet below. If an unknown userid is used, again everything works fine. If I try logging in with a valid userid but get the password wrong, that connection is rejected (see second logfile snippet), and all subsequent connection even with correct userid/password are rejected with thunderbird getting a temporary auth failure (see third logfile snippet below). I am using auth_bind = yes and it seems as though after the failed login with an incorrect password, dovecot is loosing the dn & dnpass settings for the initial user lookup. I have found numerous references to PHP and ActiveDirectory on Win2k3 getting a similar "ldap_search() failed: Operations error" error and they suggested ensuring LDAP Version 3 is used and the Deref is set to 'never'. I am already using these setting to no avail. Has anyone else experience these problems, or have any suggestions on how to overcome it ?

[Dovecot] imap+ssl feedback

I've been using 1.0rc5 since August 2nd. Thunderbird users on multiple platforms haven't had any problems saving messages to the Sent mailbox. I know from reading release notes that the SSL proxy code in rc5 is different from rc6, but I have to admit to being leery about upgrading since it works for me. Here's my configure command: ./configure --without-shadow --localstatedir=/var --with-notify=kqueue --with-cyrus-sasl2 --without-gssapi --without-vpopmail --prefix=/usr/local --build=i386-portbld-freebsd5.3 Thanks for your hard work!

[Dovecot] Possible to alias ("ln") a folder?
by scianos＠speakeasy.net 15 Aug '06

15 Aug '06

Greetings - I've got an interesting issue that has cropped up due to some brain-dead "functionality" in mobile Windows Mobile clients... Our mail infrastructure traditionally uses "Sent" as our sent items folder. This is the default. However, WM puts it's sent messages in a folder called "Sent Items", and does not let you change it. Is there any proper and/or elegant way to alias the Sent folder to Sent Items (and allow both to coexist as the same message store) in an automated fashion without needing to set this up for each user? Thank you in advance for you help and patience! - Stu

[Dovecot] dovecot tring to load sql modules

The RPM requires the above SQL library module, among others (inc. postgresql and sqlite). However: 1. Why do I need ANY SQL library??? I want PAM to do the authorization. 2. If I have to use SQL, I want Dovecot to use PostgreSQL (which I have installed and am using in another application). I hope the above is a dumb question, because that means the fix is easy. No, I'd rather not build my own; that's why I picked an RPM. Running Fedora Core 1. -- Dean

[Dovecot] duplicate uids in Outlook
by Faisal Shaikh 14 Aug '06

14 Aug '06

Hi, I run a Postfix/Dovecot server with Outlook 2002, Thunderbird clients as well as a Squirrelmail setup. All use IMAP to query the server. I recently converted our mail spool from mbox to maildir. After the conversion, one of the users is receiving two types of error messages which appear in a popup window. 1. The first popup says the following The UI D of a message changed unexpectedly. This typically indicates a server bug. Your program may not function properly after this. It then gives details of the MsgSeqNum, old UID and the new UID. 2. The second popup says Your server has reported a UID which does not comply with the IMAP standard. This typically indicates a server bug. Your program may not function properly after this. Ive searched for this on google and it has been reported before, but there are no reports of a solution or workaround. I would really appreciate any pointers or suggestions. Many Thanks, Faisal Shaikh

[Dovecot] POP to IMAP Transition
by Yudhvir Singh Sidhu 14 Aug '06

14 Aug '06

I am using Dovecot IMAP and added an IMAP folder to an Outlook client which is also popping another account. Both account folders exist in the same client. I am wondering if I can drag the pop-ed mail to the IMAP folder, thereby transferring old mail to the IMAP folder? Outlook allows me to click and drag folders into the IMAP folder. You see where I am going with this, I wnat to transition from the old POP accounts to the new IMAP accounts and delete the old folders. Is this possible? I'd love to hear from someone who has done this. ======== Yudhvir Singh Sidhu Systems Administrator Industry-University Cooperative Research Program www.ucdiscoverygrant.org 2087 Addison Street, 2nd Floor Berkeley, CA 94720-3340 510 643 4039 fax 510 643 7839

[Dovecot] Dovecot fails to come up when using ACLs (1.0.b5)

[Dovecot] Comments in dovcot.conf files

Suggestion for comments. Why not support this syntax for comments as well as # /* comments comments */ It will allow for neater looking config files.

[Dovecot] Ignoring dot files
by Andrew 11 Aug '06

11 Aug '06

Hi, Is there any way to have dovecot ignore files begining with . in directories that contain mbox formatted mail folders (in addition to the already ignored .imap and .subscriptions)? I've looked in the docs and haven't found anything but perhaps I'm not looking in the right place. Thanks, Andrew

[Dovecot] rc6 + ssl proxy patch = no go
by Jeff A. Earickson 11 Aug '06

Timo, I nervously ran rc6 plus the patch: http://dovecot.org/tmp/ssl-proxy-openssl.c on my Solaris 9 box, in production, this morning. My dovecot.conf file is attached. Like similar reports for BSD, rc6 fell over after an hour and a half. The final syslog message was: dovecot: [ID 920869 mail.error] Login process died too early - shutting down I rolled back to rc2 for production. BTW, last night's CVS compiled ok.

[Dovecot] IMAP4rev1 broken with evolution
by Charles Bueche 11 Aug '06

11 Aug '06

Hi, I'm running 1.0rc6 on Solaris/SPARC, compiled myself against openssl. Client is Evolution 2.6.2 on my gentoo x86 laptop. As Dovecot is not yet productive, we run it parallel to UW-imap, on other ports. I use TLS. If I configure my evolution client with server-type IMAP, everything works fine. However, dovecot claims IMAP4rev1 support. However, when I set server-type to IMAP4rev1 in evolution, I get a popup : -------------------------------------------------------------------- Evolution popup : Error while Scanning folders in "IMAP server xxx.yyy.com". IMAP4 server xxx.yyy.com unexpectedly disconnected : Invalid argument -------------------------------------------------------------------- Using --debug with evolution doesn't show more. In dovecot logs, nothing interesting. I'm ready to test, so please hints me. TIA, Charles -- Charles Bueche <charles(a)bueche.ch> sand, snow, wave, wind and net -surfer

But as I cant see here which subfolder the user access, so is it possible to summerise somehow this per users mass logging witth one row, something like: imap-login: Login: anti, [192.168.20.1], PLAIN, TLS, accessed 100 folders, or just: imap-login: Login: anti, [192.168.20.1], PLAIN, TLS Or someting else? Any idea to make this happend? -- Sysadmin

[Dovecot] vacation messages (dovecot lda cmusieve)
by Rene Luria 11 Aug '06

11 Aug '06

Hi, I am experiencing some problems with vacation messages feature. Using dovecot from alpha4 to 1.0.rc6 with lda from cvs, when setting up a vacation message, there is a parameter ":days" which specifies the interval between auto-reply messages. After the first reply, should wait that amount of days before sending a new reply to the same sender. The list of sender addresses is to be kept in $maildir/.dovecot.lda-dupes Now, what happens is that at random intervals, auto-replies are sent. It happens with any account, from thirty minutes to one hour maybe. How is it possible ? How to fix it ?

[Dovecot] Pb with ssl_disable in 1.0RC6

Hi, I have a problem after upgrading dovecot 1.0rc1 to 1.0rc6. I don't use SSL at all so I have 'ssl_disable = yes' in my configuration. This works fine in 1.0rc1 but dovecot 1.0rc6 failed to start with the following error message "dovecot: Login process died too early - shutting down". Setting 'ssl_disable = no' resolves the problem but now dovecot announce TLS capability which is not what I want.

Is there a reason that CRL is required to exist in the ssl_ca_file? Could it just use it only if it's there, but otherwise ignore it? Or is this a bad idea? Is it even possible at all to tell that to OpenSSL?

[Dovecot] LDA Command time limit exceeded
by Dominique Feyer 11 Aug '06

I have many errors of this type in my logs: 2 * postfix/pipe[21511]: BC8DD3356A: to=<*****@******>, relay=dovecot, delay=1001, status=bounced (Command time limit exceeded: "/usr/local/dovecot-1.0-rc2/libexec/dovecot/deliver") My command time limit is 1000s in postfix (more than 15 minutes) After many check, I found that a lots of this error is not really an error. The mail is delivered in the mailbox, but postfix send an error message. Like if Dovecot LDA process dont exit correctly after sending a mail. Do you know this bug ? As workaround i set the command time limit to 1400s but this is too long for our customer. They need in time service. We use an NFS server as storage for all our mail.

[Dovecot] xfs quota support
by polish 11 Aug '06

Hello, quota support is out of action on xfs filesystem on my centos 4.x . Problem is that i haven't these file #include <linux/dqblk_xfs.h> on my system. Solution is simple. After instalation xfsprogs-devel you get necessary files, but you must use another header file in dovecot/src/plugins/quota/quota-fs.c. Instead <linux/dqblk_xfs.h> you should use <xfs/xqm.h>. If you advise me, how can i detect if <xfs/xqm.h> exist instead <linux/dqblk_xfs.h>, i can send patch back. I'm not familiar with autotools. existing code in dovecot/src/plugins/quota/quota-fs.c : #ifdef HAVE_LINUX_DQBLK_XFS_H # include <linux/dqblk_xfs.h> #endif new code : #ifdef HAVE_XFS_XQM_H #include<xfs/xqm.h> #endif Best regards Polish -- ********************************************************** * starnem a porad nic, rozum jako kdyby se nam vyhybal * **********************************************************

[Dovecot] Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable
by Matt Roman 11 Aug '06

11 Aug '06

So I just upgraded from Dovecot 0.99 to the latest 1.0 RC2 because I was having all sorts of Authentication problems and crashes in 0.99. The upgrade did not solve the problem apparently. Dovecot still crashes periodically and always needs to be manually rebooted.

Currently only the dovecot server talks to the maildirs. Postfix is also on this server, using the same PAM Authentication for SASL and works fine - It does not appear to be a problem with the Authentication server. Thanks in advance!!! -Matt

Re: [Dovecot] Dovecot deliver logging problem and procmail
by Gerhard Wiesinger 11 Aug '06

11 Aug '06

Hello Timo! Any ideas why it may take so long time to open big mbox files with indexes and delivered through dovecot deliver? So it looks like that something is wrong with the indexes or the algorithm. For details have a look below. BTW: procmail filtering through deliver works well now for me in production environment. I'll make some code cleanups and configuration options. Maybe I can release the patch today.

I tried to deliver some large mails (~50MB) which worked well. After sending around 500MB (10 Mails) I opened the mailbox with pine over imap. It still took a lot of time (>20s) to open the mbox. Indexes should be up2date, so why does it take so long time? After opening a second time everything is fine. Any ideas? Ciao, Gerhard

[Dovecot] 1.0.rc2 released
by Timo Sirainen 11 Aug '06

11 Aug '06

Final 1.0 release is looking to get closer. There's nothing left in my TODO list for it, so please report any old and new bugs you see. This release also makes upgrades from 0.99 more transparent with automatic renaming of .subscriptions and .customflags files with maildir. http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz http://dovecot.org/releases/dovecot-1.0.rc2.tar.gz.sig * disable_plaintext_auth=yes: Removed hardcoded 127.* and ::1 IP checks. Now we just assume that the connection is secure if the local IP matches the remote IP address. * SSL code rewrite which hopefully makes it work better than before. Seems to work correctly, but if you suddently have trouble with SSL connections this is likely the reason. + verbose_ssl=yes: Log also SSL alerts and BIO errors - If namespace's location field wasn't set, the default location was supposed to be used but it wasn't. - When copying ssl-parameters.dat file from /var/lib to /var/run its permissions went wrong if it couldn't be copied with hard linking. - Fixed filesystem quota plugin to work with BSDs. - Maildir: Saving mails didn't work if quota plugin was enabled (again) - Maildir: Messages' received time wasn't saved properly when saving/copying multiple messages at a time. Also if using quota plugin the S= size was only set for the first saved file, and even that was wrong. - passdb passwd-file: Don't require valid uid/gid fields if file isn't also being used as a userdb. - PostgreSQL: Handle failures better so that there won't be "invalid fd" errors in logs. - Don't try to expunge messages if the mailbox is read-only. It'll just cause our index files to go out of sync with the real mailbox and cause errors. - ANONYMOUS authentication mechanism couldn't work because anonymous_username setting wasn't passed from master process.

[Dovecot] imap-login (proxy) Connection queue full
by Bill Boebel 11 Aug '06

11 Aug '06

When running Dovecot (rc6 CVS dovecot-20060808) as a proxy, why would it log the following when it has not yet maxed out the allowed number of imap-login processes? Aug 10 16:23:34 director5 dovecot: imap-login: Disconnected: Connection queue full: I am seeing this logged several times per minute. From netstat, the server has 650 proxied IMAP connections and 450 proxied IMAPS connections, there are currently 10 imap-login processes running, and using the following config: login_process_per_connection = no login_processes_count = 3 login_max_processes_count = 20 login_max_connections = 225 I would think that under these conditions we should never see "Connection queue full" being logged. Thanks, Bill

[Dovecot] maildir++ specification compliance.
by Apps Lists 10 Aug '06

10 Aug '06

Hi folks. I was doing some testing this morning and realized Dovecot RC2 isn't fully compliant with the maildir++ specification. Most notably, it appears that Dovecot isn't creating a "maildirfolder" file (0 byte length) in folders it creates. >From http://www.inter7.com/courierimap/README.maildirquota.html "Within each subdirectory there's an empty file, maildirfolder. Its existence tells the mail delivery agent that this Maildir is a really a folder underneath a parent Maildir++." and "Make sure to create the maildirfolder file in any new folders created within the Maildir++." Also, GETQUOTAROOT on a folder (with messages in it) will always return the entire usage, not the usage in the folder itself. For example: INBOX - really has 100 mb of messages. Sent - has a few messages totalling 1mb. Drafts - no messages A GETQUOTAROOT on INBOX will return 101 mb, 100mb for INBOX and 1mb for Sent. Drafts will show zero, because there's nothing. Unfortunately, Sent will also show 101 mb, not 1mb. While Dovecot shouldn't be creating maildirsize files in each folder (the maildirfolder file is there to tell clients to look in .. for a maildirsize) ... it should still be able to answer queries about the number of messages (count of files in the folder) as well as the total size of all messages in that folder (sum of S=xxxx or by stat() on individual message files).

[Dovecot] Developing new Dspam Plugin
by Timothy White 10 Aug '06

10 Aug '06

This email /was/ going to be a bit of a bitch about trying to get mysql compiled in to a dovecot plugin, but I got it all working before I finished the email! :-D Ok, basically what I am doing (Johannes permission) is modifying the dspam plugin, so that it instead talks to a database (MySQL in this case), and updates a table, so that you can do the actual training at a time of lower load. It /does/ require MySQL >= 5 cause I am using stored PROCEDURE's, which gives you the advantage, that you can use the same plugin, without changing anything, regardless of what your database looks like, or how you want the database to work! :-D I have successfully modified Johannes plugin to call SPAM and HAM in the database, with the signatures, and also upgraded it to work with beta9. I also made the small change of a define for the Spam folder, so that if your Spam folder is named differently, you don't have to change the code in 2-3 places as well ;-) I am yet to write any 'batch' code for processing the database tables, but that is fairly trivial, and I could even write it in php if I wanted ;-) (If you want something to do, go ahead and write me a C client to do this! I'll get to it eventually, and you can reuse most of the code from the plugin!) See http://members.plug.org.au/~linuxalien/dokuwiki/projects:dovecot-mysql-dspa… for more details, and the code! Feed back, comments, and criticism are all welcome! Tim -- Linux Counter user #273956

[Dovecot] Complex MySQL query in dovecot-sql.conf
by Timo Neuvonen 10 Aug '06

10 Aug '06

Is there some limit for the maximum length of the line in dovecot-sql.conf? In particular, I would be writing a long MySQL password query. And further, can a long line be somehow split to several pieces? I tried the common unix-style way of putting backslash as the last character of the first line, but it results in an error immediatedly while restarting Dovecot (while parsing the conf, ie. not a MySQL error): (in conf:) password_query = SELECT user, password FROM users\ WHERE user='%u' AND active='Y' (results in log, line 88 refers to line starting with 'WHERE':) auth(default): Error in configuration file /etc/dovecot-mysql.conf line 88: Expecting '=' The example above is just the beginning, what comes to my question about a long line. I would be checking %r (remote ip) against user-specific allowed ip-address ranges given in the database. Actually, I'd like to use some MySQL user-defined variables within my query, for example to keep only the 3 highest octets of the IPv4 representation of %r (eg. '192.168.0') so I could easily check against allowed /24 networks stored in the database. That seems to run into another problem. A very simplified example what happens when I try to define a variable within the query: (in conf, split to two lines for news only:) password_query = SET @yes='Y'; SELECT user, password FROM users WHERE user='%u' AND active=@yes (results in log:) Password query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '; SELECT user, password FROM users WHERE user='testi' AND active=@yes' at line 1 Anyway, a similar one-line construct works from the MySQL command line: SET @yes='Y'; SELECT user, password FROM users WHERE user='testi' AND active=@yes; (reults the following:) +-------+----------+ | user | password | +-------+----------+ | testi | 123 | +-------+----------+ Any ideas? Am I doing something in a completely wrong way? Of course, split lines & variables are not absolutely necessary, they just would improve readability & shorten the query. But if there is no limit on the length of the query, I propably can write everything as a one long SELECT command... I'm trying all this on Fedora Core 5, having - dovecot-1.0-0.beta8.2.fc5 - mysql-5.0.22-1.FC5.1 Regards, Timo Neuvonen

[Dovecot] My view on 1.0 release and version numbering
by Marc Perkel 10 Aug '06

10 Aug '06

Just throwing out some thoughts here. I know Timo has high standards and is trying to make 1.0 bug free before calling it 1.0. But I want to argue for an earlier less perfect 1.0. Dovecot is already way past the quality of most 1.0 releases. So it is good enough by common standards. No one really expects a 1.0 release to be perfect. But - some people don't consider a product ripe until it reaches 1.0. Once you cross the line then more people will pick it up and you will get more bug reports because of a larger base. This would actually accelerate the debugging process. And it will spur acceptance of the product and perhaps bring in more developer resources. Generally 1.0 is still buggy. It is usually followed quickly with 1.0.1, 1.0.2 ... and then stabilizes. Then as more people ask for new features it spawns 1.1.0 which is somewhat buggy and then 1.1.1 and by 1.1.2 it's rock solid. So - I'm not suggesting Timo go to 1.0 immediately. I'm just saying that I think it's pretty ripe and sooner is better than later. My 2 centz ...

[Dovecot] Dovecot under daemontools
by dale gallagher 10 Aug '06

10 Aug '06

Hi there I'm having difficulties in getting dovecot to run under daemontools. Also, from a sysadmin perspective, so far, I find dovecot's config rather complex - I suppose that's what happens when one attempts to appease all authentication methods... anyway, I digress. System details, to set the scene: OS: Slackware Linux Linux Kernel: 2.4.29 GCC: 3.2.2 Dovecot version: 1.0.rc6 Dovecot configure options: ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --with-checkpassword --without-passwd --without-passwd-file --without-shadow --without-pam --without-bsdauth --without-gssapi --without-ldap --without-vpopmail --with-prefetch-userdb --without-sql --without-pgsql --without-mysql --with-ssl=openssl --without-pop3d --with-storages=maildir --without-deliver MTA: qmail Storage: Maildirs under a single virtual user (vmail) Checkpassword: /var/qmail/bin/qmail-vpoplogin (modified cdb checkpassword) User DB: /var/qmail/users/vpasswd.cdb /etc/dovecot.conf base_dir = /var/run/dovecot protocols = imap listen = 127.0.0.1 ssl_disable = yes shutdown_clients = yes log_path = /var/log/dovecot login_dir = /var/run/dovecot/login maildir_copy_with_hardlinks = yes protocol imap { # only require access from webmail on same host listen = 127.0.0.1:143 } auth default { passdb checkpassword { args = /var/qmail/bin/qmail-vpoplogin } userdb prefetch { } # user who can access user/passwd db user = auth } Firstly, I cannot run dovecot as an unprivileged user, as the OS moans that the user doesn't have permission to write to /dev/stderr. I've had a similar issue running Clamav, but a patch to Clamav resolved this? This seems to be related to referencing /dev/stderr directly. Any ideas? Should I be running dovecot as the virtual mailbox user vmail? Before I ramble on about what I've tried, could someone explain to me what dovecot actually does, in terms of privilege separation? The online docs are somewhat convoluted. This would help shed light on the solution. I also noticed the posts re daemontools some time ago, yet they do not include any setup solutions etc - I'd appreciate details from those of you who've succeeded in this regard. Thanks Dale

[Dovecot] userdb prefetch problem..
by Mike 10 Aug '06

10 Aug '06

I have a setup that I'm working on migrating to Dovecot for thousands of users across a few dozen domains.. All users are authed from LDAP.. In LDAP, each user has a unique uidNumber, and varying gidNumber (for use in other applications) As far as mail storage, the entire Maildir structure is owned by UID/GID: vmail/vmail So, the uidNumber/gidNumber from LDAP is not needed. global uid/gid is set to 'vmail' When using "passdb ldap" and "userdb ldap" both pointing to dovecot-ldap.conf, and removing the "uidNumber=uid"..etc from the "_attrs" lines, this works just fine. I would like to use "userdb prefetch" to use one less ldap query, but the uid/gid stuff is giving me some problems. The appropriate line in - dovecot-ldap.conf: pass_attrs = mail=user,userPassword=password,homeDirectory=userdb_home I get the following erros in the log: .... .... dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_uid not returned dovecot: auth(default): prefetch(user(a)domain.com,127.0.0.1): userdb_gid not returned dovecot: auth(default): userdb(user(a)domain.com,127.0.0.1): user not found from userdb dovecot: auth(default): master out: NOTFOUND 1 dovecot: pop3-login: Internal login failure: user=<user(a)domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any help is appreciated! -Mike FreeBSD 6-1-RELEASE OpenLDAP 2.3 Dovecot 1.0rc2

[Dovecot] 1.0 RC1 status
by Timo Sirainen 10 Aug '06

10 Aug '06

Today I finally caught up with my mail. I've now read all the mails from the Dovecot list from this year and all my private mails from last few years (totaling around 500 unread mails). If you think there's still something I should have replied to, please re-send it because I've either missed it or just skipped it for some reason. (Except there are still a couple of mails from this week I've yet to reply to.) Besides reading mails I've also fixed a lot of bugs today. What's left from my original 1.0 roadmap is: - Solaris sendfile is broken? Is it? Can someone try? You can test it with maildir by setting mail_save_crlf=yes, saving a somewhat large mail and FETCHing it (and truss that it really uses sendfile) - LDA: empty mail gives an error. - quota code should probably be always doing some quota_set_critical() instead of using mail_storage_set_critical(), so that quota_last_error() would work properly - rfc2557 support for BODYSTRUCTURE, as specified by RFC3501 - keywords: add some limits to how many there can be - don't return \* in PERMANENTFLAGS when we're full - mbox: how well does dirty sync + status work? it reads the last mail every time? not very good.. - mbox: dirty state should be stored to index (with mbox_very_dirty_syncs) I think 1.0 could be released without any of those changes. But what about the connection hangs that some people have had? Do they still occur? Is it only with SSL? I guess I should look at my previous ssl-proxy rewrite, figure out what went wrong with it and try again. I'm thinking about releasing 1.0 RC1 within a few days. Would be nice if that release actually worked, so testing would be appreciated :) You can try it by getting the dovecot-latest from http://dovecot.org/nightly/ The current changes include: * PAM: If user's password is expired, give "Password expired" error message to the user. Now actually working thanks to Vaidas Pilkauskas * Relicensed dovecot-auth, lib-sql and lib-ntlm to MIT license. See COPYING file for more information. * Abuse prevention: When creating a mailbox, limit the number of hierarchies (up to 20) and the length of the mailbox name within a hierarchy (up to 200 characters). * mbox: If saved mail doesn't end with LF, add it ourself so that the mails always have one empty line before the next From-line. + Added --with-statedir configure option which defaults to $localstatedir/lib/dovecot. ssl-parameters.dat is permanently stored in that directory and is copied to login_dirs from there. + IMAP: Support SASL-IR extension (SASL initial response) + Support initial SASL response with LOGIN mechanism. Patch by Anders Karlsson + Added PLAIN-MD4 password scheme. Patch by Andrey Panin. + Added support for XFS disk quotas. Patch by Pawel Jarosz + If another process deletes the opened mailbox, try to handle it without writing errors to log file. Handles the most common cases. + Added TLS support for LDAP if the library supports it. - Dovecot corrupted mbox files which had CR+LF linefeeds in headers - MySQL code could have crashed while escaping strings - MD4 code with NTLM authentication was broken with 64bit systems. Patch by Andrey Panin - Plugin loading was broken in some OSes (eg. FreeBSD) - Several fixes to handling empty values in configuration file - Several fixes to dictionary quota backend and dict server. Also changed how they're configured. - deliver: Fixed plugin handling settings - mbox_min_index_size handling was somewhat broken - passdb passwd-file: extra_args field wasn't read unless the file was also used as userdb.
