[Dovecot] Virtual Users and Local Users Authentication
by craig carriere 19 Jan '07

19 Jan '07

I am using dovecot on a SLES 10 mail server using postfix as the MTA. The original setup used local users and a single domain. I have now configured postfix to send mail to a second virtual domain which is working fine. I am trying to get dovecot to pick up the mail and have been having authentication problems. My local users uses pam and /etc/passwd for login with SSL. I have created a passwd file for the virtual users and have set dovecot to look at the passwd-like file with the path specified. However dovecot complains about the file not being present, which it is and my local users can not login. Probably doing something simple incorrectly, but can not find what fron online searches.

[Dovecot] Migrating from UW-IMAP
by Jay Chandler 19 Jan '07

19 Jan '07

Greetings. I've got a poorly conceived and implemented system I'm trying to migrate off of. Right now we've got 20K accounts or so, in mbox form, under UW-IMAP. Eventually we're going to move to Maildir format, but the first step is to move to Dovecot on one of our imap servers as a proof of concept. In other words, all config changes have to take place on the dovecot side, until I get PHB approval to proceed further. Right now, the inboxes are the user's username, located in /var/mail (an NFS mounted volume). So my inbox would be at /var/mail/chandler. The sub-mailboxes are in the user home directories, just scattered around-- no /mail subdirectory or anything close. So there's a folder called ~chandler/INBOX.Sent, ~chandler/INBOX.Trash, and a ~chandler/Dovecot (for this list). The list of these files is kept in ~chandler/.mailboxlist. I attempted to follow the instructions at http://wiki.dovecot.org/Migration about: You can either rename your .mailboxlist file to .subscriptions for all your users using uw2dovecot.sh <http://wiki.dovecot.org/uw2dovecot.sh>, or change the definition of SUBSCRIPTION_FILE_NAME in /src/lib-storage/subscription-file/subscription-file.c/. In 1.0-test, this value is defined in /src/lib-storage/subscription-fileindex/maildir/maildir-storage.h/ and /src/lib-storage/subscription-fileindex/mbox/maildir-storage.h/. .subscriptions is located inside of the mail directory, whereas it is possible .mailboxlist was outside of it (in user's home directory). However, I built dovecot from ports on FreeBSD 6.2, and the only files that approach this are: wurfel# ls -al total 58 drwxr-xr-x 3 root wheel 512 Jan 16 20:48 . drwxr-xr-x 6 root wheel 1024 Jan 16 20:48 .. drwxr-xr-x 2 root wheel 512 Jan 16 20:48 .deps -rw-r--r-- 1 root wheel 14662 Jan 16 20:48 Makefile -rw-r--r-- 1 root wheel 266 Oct 20 2004 Makefile.am -rw-r--r-- 1 root wheel 14009 Jan 6 23:26 Makefile.in -rw-r--r-- 1 root wheel 4374 Jan 16 20:48 libstorage_subscription_file.a -rw-r--r-- 1 root wheel 6935 Jan 3 15:19 subscription-file.c -rw-r--r-- 1 root wheel 703 Jan 13 2006 subscription-file.h -rw-r--r-- 1 root wheel 4060 Jan 16 20:48 subscription-file.o wurfel# pwd /usr/ports/mail/dovecot/work/dovecot-1.0.rc17/src/lib-storage/subscription-file I took a look at subscription-file.c, but didn't notice where I should change the definition of the file itself-- my code-fu is weak. If someone could lend a hand, I'd be deeply appreciative.

[Dovecot] Bounce vs. Defer
by Jeff Mitchell 19 Jan '07

19 Jan '07

Hello-- I've noticed that with when using deliver, if there is a misconfiguration in my dovecot configuration file, a permissions problem on the maildir, etc., deliver will bounce the message. I'm using Postfix, and at some point used Maildrop, and I know that maildrop (and I believe also Postfix's virtual transport) instead defer the message if there is some kind of fixable problem (like permissions). Then, when the problem is solved, you can flush the queue. Would it be possible to add a defer option to deliver? It makes it difficult to try out new options or different configurations because if you have fairly regular incoming mail, the last thing you want is a ten minute period where 20 messages get bounced... Thanks, Jeff

[Dovecot] dovecot as POP3 proxy
by Alexander Shikoff 19 Jan '07

19 Jan '07

Hello, I am trying to set up dovecot as pop3 proxy. There is net lines in my auth section: passdb passwd-file { args = /usr/local/etc/dovecot/proxy.users } userdb static { args = uid=26 gid=6 } File proxy.users should contain a list of users. Now it looks like test:::::::proxy host=10.10.10.10 and everything is OK. My question is how to change passwd-file in order to match any username? I need something like *:::::::proxy host=10.10.10.10 Thanks in advance! -- Kind Regards, Alexander Shikoff

[Dovecot] FreeBSD, Postfix, Cyrus SASL, Dovecot IMAP, SquirrelMail, Active Directory
by Phil Anslemo 19 Jan '07

19 Jan '07

Here's an update to my configuration. I'm able to use Cyrus SASL to enable SMTP AUTH in PostFix, validate user's mail addresses in Active Directory, and store mail in maildir on FreeBSD. I am currently able to authenticate AD users with Dovecot and LDAP, but I'm getting the following error in the log: Error: IMAP(user@domain): Ambiguous mail location setting, don't know what to do with it: user@domain (try prefixing it with mbox: or maildir:) Error: IMAP(user@doman): Failed to create storage data: user@domain. Error: child xxxxx (imap) returned error 89 I double-checked dovecot.conf, and the mail_location setting is "mail_location = maildir:/usr/data/vmail/%u". I'm not sure what could be happening, but I'm thinking this is the last thing I need to get my configuration to work. Your assistance is greatly appreciated.

by Zied Fakhfakh 19 Jan '07

19 Jan '07

Hi everybody, this is my first post to the list. I'm setting up a mail server with sendmail/LDAP/Dovecot (all latest version on FC6) I'm trying hard to get sendmail deliver through dovecot "deliver" I followed the instructions at the wiki: http://wiki.dovecot.org/LDA but I can't get it working. i cannot find the problem where ? when I do this as mailer: some.domain.com dovecot:dovecot or this: some.domain.com dovecot.mail.host.net sendmail always reports (on the maillog) an unknown mailer error: ...... stat=unknown mailer error 80 path to deliver is checked and executable by everyone (/usr/libexec/dovecot/deliver) can someone help please ? BTW : I manager to create a dovecot.m4, that way we can add "MAILER(dovecot)" to sendmail.mc if you are interested I will post it. Regards, Zydoon.

[Dovecot] Build problems with non-standard location of mysql libs
by Bob 19 Jan '07

19 Jan '07

Overall the build process for dovecot is very clean. I did however run into a significant problem when it came to locating the mysql libraries, especially when building a 64 bit executable but similar problems occured building a 32 bit executable. I am describing the 64 bit build issues below since that is the worst case scenario. Fixing the 64 bit build will automatically fix the 32 bit build. In the Solaris world it is fairly common for software packages to be installed in the /opt tree rather than under /usr or /usr/local. In addition 64 bit libs are typically located under a path like /opt/lib/64 or /opt/lib/sparcv9 and of course mysql libs are under /opt/lib/mysql or /opt/lib/sparcv9 | 64/mysql. The configure script for dovecot tries only a lib64 or /usr/lib64 path I suggest that the conifgure script for dovecot offer a --with-mysql[=DIR] option so that it would be possible to provide the base location of the mysql installation as --with-mysql=/opt in the same manner that it is done for php. I patched the configure script to search the /opt tree for mysql but unfortunately a side effect occured during the build which was compiled as 64 bit with the necessary CFLAGS and LDFLAGS input to the configure script. Here is the configure. Note that the library search paths also include the Solaris specific sparcv9 paths so nothing special is required in the configure script to account for these platform specific paths. This is exactly the same method the we use to build php as a 64 bit app successfully. However, the configrue script needs to locate the /opt/include/mysql directory and also needs to find /opt/lib/mysql to at least trigger that it found the mysql installation. Even though /opt/lib/mysql is the path to the 32 bit library, the link tests will pass because the supplied LDFLAGS contain the path to the 64 bit library. CFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ CXXFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ LDFLAGS="-O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -L/opt/lib/sparcv9/mysql -R/opt/lib/sparcv9 -R/opt/lib/sparcv9/mysql" \ ./configure --prefix=/opt \ --localstatedir=/var \ --enable-shared \ --disable-static \ --libdir=/opt/lib/sparcv9 \ --with-ssldir=/opt/ssl \ --with-ssl=openssl \ --with-storages=maildir,mbox \ --with-mysql The next problem was that dovecot-auth failed to link: /bin/bash ../../libtool --tag=CC --mode=link gcc -std=gnu99 -O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -R/opt/lib/sparcv9 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/opt/include -export-dynamic -O3 -m64 -mcpu=ultrasparc -L/opt/lib/sparcv9 -R/opt/lib/sparcv9 -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lpam -L -L/opt/lib/mysql -L/opt/lib/sparcv9/mysql -lmysqlclient -lz -lm -export-dynamic -ldl -lsocket -lnsl -lrt mkdir .libs gcc -std=gnu99 -O3 -m64 -mcpu=ultrasparc -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -I/opt/include -O3 -m64 -mcpu=ultrasparc -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o -L/opt/lib/sparcv9 libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lpam -L/db/src/dovecot/dovecot-1.0.rc17_64bit/src/auth -L/opt/lib/mysql -L/opt/lib/sparcv9/mysql /opt/lib/mysql/libmysqlclient.so -L/opt/lib -lposix4 -lgen -lssl -lcrypto -lz -lm -ldl -lsocket -lnsl -lrt -R/opt/lib/mysql -R/opt/lib/mysql -R/opt/lib/sparcv9 ld: fatal: file /opt/lib/mysql/libmysqlclient.so: wrong ELF class: ELFCLASS32 ld: fatal: File processing errors. No output written to dovecot-auth What is odd about the above is that the input to libtool is completely correct but the resulting gcc command converted -lmysqlclient to an absolute path of /opt/lib/mysql/libmysqlclient.so which is wrong for a 64 bit build - hence the link failure. Why this happened is a mystery to me? If it had been left alone as -lmysqlclient the link would have been successful because the correct 64 bit library would have been found automatically. To get around this problem I added -lmysqlclient to the LDFLAGS input to the configure script which works but isn't very conventional. It would be much cleaner if the --with-mysql had a [=DIR] option and the configure script used the same basic logic that is used in the php configure script for locating the mysql stuff. In addition it is essential that hard paths, especially to shared objects don't get generated during the build since that will block the automatic searching of libraries. -- *Bob Atkins * /President/CEO/ *DigiLink, Inc. <http://www.digilink.net>* Business Inter-net-working */The Cure for the Common ISP!/* Phone: (310) 577-9450 Fax: (310) 577-3360 eMail: bob(a)digilink.net

[Dovecot] Vpopmail auth with vchkpw
by Rick Romero 19 Jan '07

19 Jan '07

Hey Guys, I'm using vpopmail, and was told here that I need to use the vchkpw passwd module to authenticate AND get my lastauth data updated. It works like a charm, but I've come across another minor issue. vchkpw sets the 'connection-type' based on the variable TCPLOCALPORT If that's not set, it defaults to pop. What this does in my environment is cause someone who is denied POP access to also not be able to use IMAP (or webmail) because that variable is not set. Is it possible to have Dovecot set that variable, based on the port the user connected to, prior to calling vchkpw? Or can I Set that in here somehow? passdb checkpassword { args = /usr/local/vpopmail/bin/vchkpw } userdb prefetch { } } Thanks Rick

[Dovecot] Shared folder
by Stefan Klatt 19 Jan '07

19 Jan '07

Hi, first.. i'm new on this list :-) and use dovecot 1.01rc17 under fedora core 5. And i read the list of the last 4 moth and didn't found answers to my questions........ now i work with shared folders and got it running on the following configuration: namespace private { seperator = . prefix = location = maildir:/srv/imapd/user/%u/maildir inbox = yes } namespace public { seperator = . prefix = Public. location = maildir:/imapd/shared/public/maildir:CONTROL=/imapd/user/%u/shared-settings/public/control:INDEX=/imapd/user/%u/shared-settings/public/index hidden = no } location is one line :-) I have different questions to this configuration: if i use "hidden = no" at the private namespace, the complete namespace isn't viewable, if i use "hidden = yes" i see the prefix "private" at the foldernames in my emailclient. Shouldn't be a non existing hidden option the same like "hidden = no"? if use / as the seperator like dokumented at the wiki it doesn't work. with a dot like the seperator at the directories for the emailfolder it works. is there a way to implement ACL for virtuell user in this configuration? The namespace could be a very interesting idea to give other user access to the own mailbox (e.g. for holiday), but for this each user need it's own acl-file which he can change.... And the special folder like Inbox must be viewable from another user. The both last could be realized with an option like "ACL = /imapd/user/%u/rights" to include an file with acldefinition at the namespacedefiniton. Another way could be a option like "ACL_R = user, user, group, group" inside of the namespacedefinition with definition of user and group outside of the namespacedefintion. For me a LDAP request would the best way :-) i realize the complete emailconfiguration with ldap. Stefan

[Dovecot] How change the order POP checks mail.
by Andreas Andersson 19 Jan '07

19 Jan '07

Hello! I have a problem with the POP when I want to use mbox and Maildirs. The old users are now using uw-imap, but in the future should theres old e-mail be in mbox format and the new e-mails in maildirs. I'am using this code and its worked fine in Squirrelmail and IMAP. namespace private { separator = / inbox = yes hidden = no prefix = "mbox/" location = mbox:~/mail:INBOX=/var/mail/%u } namespace private { separator = / prefix = location = maildir:~/Maildir } but not with POP, I can't find any mail. When I only searching for mbox mail, it worked great. I think thats the problem are the pop who first searching for Maildirs and then mailboxes. So how could I get the Dovecot POP server to first check the mailboxes and then the maildirs? Or how should I go around this problem? Thanks! Andreas Andersson

[Dovecot] rc17: child 15802 (auth) killed with signal 6
by Chris Laif 19 Jan '07

19 Jan '07

I'm using dovecot (rc17) in POP3/IMAP server _and_ proxy mode (pgsql backend). Everything works fine but occasionally I get these messages in the log: dovecot: auth(default): file passdb.c: line 126 (passdb_handle_credentials): assertion failed: (password != NULL) dovecot: auth(default): Raw backtrace: dovecot-auth [0x8062b2b] -> dovecot-auth [0x8062599] -> dovecot-auth [0x805a6ae] -> dovecot-auth [0x805b3b8] -> dovecot-auth [0x8060350] -> dovecot-auth(io_loop_handler_run+0x118) [0x8066458] -> dovecot-auth(io_loop_run+0x28) [0x80658e8] -> dovecot-auth(main+0x78) [0x8057028] -> /lib/libc.so.6(__libc_start_main+0xc6) [0x4007ee36] -> dovecot-auth [0x804f591] dovecot: child 15802 (auth) killed with signal 6 I seems (!) that these messages only appear when someone uses dovecot in in IMAP proxy mode. As I said before, everything works fine -- even reading emails via IMAP-proxy works. Chris

[Dovecot] RC15 problems with dovecot-shared and umask distilled
by Glenn Leavell 19 Jan '07

19 Jan '07

I recently posted about problems I've been having with dovecot-shared and umask in RC15 (using Solaris 9). I've now been able to distill what I'm experiencing into these two separate points: 1. dovecot-uidlist and message files never inherit the dovecot-shared group 2. With umask=0007 these files are created with mode 600 instead of 660: dovecot-uidlist, dovecot.index, dovecot.index.log, messages files (cur,tmp,new and the parent directory *are* created 770) (With regard to #1, I originally posted that individual message files were also not inheriting *permissions* from dovecot-shared, but that turned out to be a case of copying a message with maildir_copy_with_hardlinks = yes.) I can duplicate this consistently; can anyone else? Or has this been fixed in RC16/17? Thanks, Glenn

[Dovecot] dovecot imap logging capabilities
by Michael A. Painter Jr. 18 Jan '07

18 Jan '07

Hello, I have searched but have not found any information on logging imap actions. I want to log when someone uses imap to delete, move, copy, etc. This would greatly help me when someone deletes an email and asks where it went. I get this fairly often from a few users. Any help would be greatly appreciated. Thank you, Michael A. Painter Jr.

[Dovecot] A few rc17 imap crashes
by Chris Wakelin 18 Jan '07

18 Jan '07

We upgraded from 1.0-beta7 to 1.0-rc17 on Tuesday evening and looking at today's logs, just four imap processes out of 90,000+ died. I managed to get core files (the server is running Solaris 8 on Sparc, and Dovecot was compiled with gcc 3.3.2). I hope they're useful! (I should also say that performance between the two versions is roughly similar according to Solaris' process accounting stats, looking at CPU usage and disk blocks accessed.)

[Dovecot] default_mail_env/mail_location syntax changes
by Mike Brown 18 Jan '07

18 Jan '07

Sorry, I tried to find this info on the wiki and in the docs, but couldn't quite figure it out. Dovecot 1.0rc8 introduced this change: "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" If I need a custom INBOX location but the default behavior of using the first of [/ or ~/mail or ~/Mail] having a .imap subdirectory, how do I go about specifying that? That is, on my system, - inbox file: ~/Mailbox - mail storage dir: ~/mail OR ~/Mail (it varies by user) - all files are in mbox format Thanks, Mike

[Dovecot] some Maildir files not honoring dovecot-shared
by Glenn Leavell 18 Jan '07

18 Jan '07

I'm using RC15 on Solaris 9. The wiki indicates that when a dovecot-shared file exists, "Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc." In my case, Dovecot *is* creating new index files based on dovecot-shared, but dovecot-uidlist and individual message files don't completely match the permissions/group template. Specifically, dovecot-uidlist isn't taking the group from dovecot-uidlist, and individual messages files don't seem to be honoring dovecot-shared at all (group or permissions). Here's an example; every file and directory below in .abusetest-in was created by Dovecot *except* for dovecot-shared (I let Dovecot create cur, new, tmp just to see what it would do, but I know that I can create and fix the group and permissions on these directories myself in a sharing situation): glenn@tony:~/Maildir/.abusetest-in$ ls -lR .: total 34 drwx------ 2 glenn adm 512 Jan 9 09:58 cur/ -rwxrwx--- 1 glenn abuse 0 Jan 9 09:57 dovecot-shared* -rw-rw---- 1 glenn adm 44 Jan 9 09:58 dovecot-uidlist -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index -rw-rw---- 1 glenn abuse 10272 Jan 9 09:58 dovecot.index.cache -rw-rw---- 1 glenn abuse 156 Jan 9 09:58 dovecot.index.log drwx------ 2 glenn adm 512 Jan 9 09:58 new/ drwx------ 2 glenn adm 512 Jan 9 09:58 tmp/ ./cur: total 4 -rw------- 2 glenn adm 1438 Jan 5 09:59 1168354728.P15661Q0M891161.tony:2,S ./new: total 0 ./tmp: total 0 glenn@tony:~/Maildir/.abusetest-in$ I see in the RC16 release notes that there was a fix for the dovecot-keywords file, but it doesn't mention these other files. Is this a bug, or am I misunderstanding how the dovecot-shared file should work?

[Dovecot] assertion failed

I installed dovecot on a RH9 server this evening, via an RPM from atrpms.net (dovecot-1.0-0_34.rc15.RHL9.at.i386.rpm). The auth portion is working perfectly, as I'm using it to do SMTP AUTH with my postfix 2.3.5 installation. I have configured it to provide imaps.
