[Dovecot] Director and forwarding LDAP user as Master user
by Alexandr Sabitov 08 Jan '13

08 Jan '13

Hello guys, Would you be able to help me with this little issue. I bet someone has the same config so if you can copy-paste it I will very appreciate it. So main idea is to enable Dovecot director to authenticate a LDAP user with plain or encrypted password and send the user to back-end Dovecot server after the authentication. According to Wiki it is only possible if we use the master user to communicate to the back-end server. On the back-end Dovecot server it is working fine, I can log in as normal user/user_password or as user*masteruser/master_password. The back-end config is: auth_master_user_separator = * passdb { driver = passwd-file args = /usr/local/dovecot/etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } Now front-end: how to get director forward the user to the back-end after authentication on the director? With my director config the user stays on the director all the time: passdb { driver = static args = proxy=y master=masteruser pass=master_password destuser=%u*masteruser } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } The only way to forward the user is to setup nopassword=y in args of static passdb but in that case the user will be authenticated on the backend but not on the director... What do I missing ? Please help me Best Regards, Alexandr Sabitov

[Dovecot] Non-standard fields?
by Attila Nagy 04 Jan '13

04 Jan '13

Hi, Non-standard fields are mentioned here: http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as currently not used. Questions: - am I right that if they will be used, they will be key=value pairs, like fields in the base filename? Like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something - or are they supposed to be flags, like: 1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD - are there any plans to utilize these? Thanks,

[Dovecot] Dovecot Virtual Users with Sendmail
by DormitionSkete＠hotmail.com 04 Jan '13

04 Jan '13

I'm trying to get Dovecot working with Virtual Users and Sendmail on OpenIndiana 151a7. OpenIndiana is the Open Source continuation of OpenSolaris after Oracle tried to kill it off a couple of years ago shortly after acquiring Sun Microsystems. I'm not sure if this is so much a Dovecot problem, as much of a Sendmail problem. I thought this would probably be a better list to start with, though. If not, please let me know. I initially used this Dovecot wiki page to approach this: Simple Virtual User Installation http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I had to make few minor changes, but I don't think anything significant to the problem I'm having. I can log into SquirrelMail with both virtual users, and with system users. I can send mail to system users from both virtual and system users. I can see the mail that I sent in the Sent Messages folder for both types of users. I just can't send mail to virtual users. When I try to, I get the following message: ERROR: Message not sent. Server replied: Requested action not taken: mailbox unavailable 550 5.1.1 <dswebstore@localhost>... User unknown My configuration info is as follows: systemuser@openindiana:~# /usr/local/sbin/dovecot --version 2.1.12 systemuser@openindiana:~# /usr/local/sbin/dovecot -n # 2.1.12: /usr/local/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 101 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = mbox:/home/vmail/%u/mail:INBOX=/var/mail/%u passdb { args = /usr/local/etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } } ssl = no userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { postmaster_address = systemuser@localhost } --- My dovecot password file looks something like this, though changed for obvious security reasons: systemuser:{PLAIN} systemuserPASS virtualuser1:{PLAIN}virtualuser1PASS virtualuser2:{PLAIN}virtualuser2PASS --- I read on this page that I needed to put the following in my sendmail dovecot.m4 file: Dovecot LDA with Sendmail http://wiki2.dovecot.org/LDA/Sendmail So this is my dovecot.m4 file, which shows up in my sendmail.cf file after recompiling my sendmail.mc file. ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u --- Finally, this is my sendmail.mc file: divert(-1) # # Copyright (c) 1983 Eric P.

[Dovecot] clucene-config.h location
by Dimitri 04 Jan '13

04 Jan '13

By deafult, CLucene installs the clucene-config.h header to /usr/lib/CLucene, but fts-lucene tries to include it from /usr/include/CLucene and fails. Here is how it is fixed in Fedora, for instance: sed -i '/DEFAULT_INCLUDES *=/s|$| '"$(pkg-config --cflags libclucene-core)|" src/plugins/fts-lucene/Makefile.in Indeed, Lucene's pkgconfig file reflects the fact that some headers reside in /usr/lib/CLucene. It would be great if Dovecot used pkgconfig for CLucene. Thanks, Dimitri Mageia Linux packager

[Dovecot] Dovecot 1.2.7 and Roundcube LIST-EXTENDED commands
by aristidis fesarlis 04 Jan '13

04 Jan '13

Hi all, we use Dovecot 1.2.7 with Maildir, and recently we have set up the latest Roundcube webmail. Inside its config file,it is mentioned that: // By default list of subscribed folders is determined using LIST-EXTENDED // extension if available. Some servers (dovecot 1.x) returns wrong results // for shared namespaces in this case. http://trac.roundcube.net/ticket/1486225 // Enable this option to force LSUB command usage instead. I notice that it seems to work fine, though. We don't have shared namespaces. So my question is: should I change it to LSUB, or will I have problems with my Maildir subscriptions? Thanks

[Dovecot] Kerberos/GSSAPI auth via .k5login file
by Jörg Herzinger 04 Jan '13

04 Jan '13

Hi, we are currently moving our mailserver to a new server with Dovecot, virtual users in LDAP, Passwords in Kerberos Setup. Everything works fine except for GSSAPI which seems to be a bit buggy. The thing is, that when using a .k5login [1] file it seems that SASL does not get passed the home directory specified userdb. In other words, mails for user1 (see below) are stored in /home/domain.at/user1, while the home dir defined in LDAP is /afs/domain.at/home/user1 (virtual users, so only dovecot, not the system does know about this user and home dir). If I do create a .k5login file in /home/domain.at/user1 with the content "someotheruser(a)DOMAIN.AT", then someotheruser should be able to authenticate himself as user1 via GSSAPI. However, this .k5login file is completely ignored. So it seems to me that the home is not passed on to SASL. If I do add ldap to my nsswitch (for testing only) I additionally have real system users. Now if I create a .k5login in their home defined in LDAP which now also the system knows about everything works just fine. It is still the wrong home since its the one in LDAP and not the one defined by dovecot but at least it shows that our setup is working. See also debug log output below, a failed GSSAPI attempt produces no log output at all. Our System is Debian Wheezy on an amd64 (virtualized), dovecot Version 2.1.7, filesystem is ext4. Everything is tested with Firefox 17.0 on an Ubuntu Lucid client.

[Dovecot] dovecot crashing?

Happy holidays! I am experiencing an issue when trying to check my mail using IMAP. with Dovecot I have tried checking my mail using a full GUI client (Thunderbird) and telnet. Both times I get disconnected before all of my messages can be downloaded and I see an error in my mail log. Here are the details: [root@cust19-1-prod-domain userqa]# dovecot --version 2.0.9 [root@cust19-1-prod-domain userqa]# dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 CentOS release 5.4 (Final) disable_plaintext_auth = no login_trusted_networks = 172.19.136.0 mail_location = maildir:~/Maildir mail_max_userip_connections = 100 mbox_write_locks = fcntl mmap_disable = yes passdb { args = scheme=plain username_format=%n /etc/dovecot/users driver = passwd-file } protocols = imap ssl = no userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } [root@cust19-1-prod-domain userqa]# i try to check my mail: username@ops1-1-domain:~$ telnet cust19-1-prod-domain imap Trying 172.19.136.223...

Not sure if you guys want to see all of the extremely verbose output, so I put it at the end of this message. The last messages that it processes is a message with an Excel spreadsheet attached to it (a .xlsx file) i enabled core dumps: echo 'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot Now I see this in /var/log/maillog: 2012-12-25T17:53:47-08:00 cust19-1-prod-domain dovecot: master: Error: service(imap): child 11265 killed with signal 11 (core dumped) core dumps are being written here, but they're empty: [root@cust19-1-prod-domain userqa]# pwd /mnt/mail/userqa [root@cust19-1-prod-domain userqa]# ls -lh total 20K -rw------- 1 userqa userqa 0 Dec 25 17:52 core.11111 -rw------- 1 userqa userqa 0 Dec 25 17:53 core.11265 -rw------- 1 userqa userqa 0 Dec 25 17:58 core.11812 drwx------ 7 userqa userqa 4.0K Dec 25 17:58 Maildir [root@cust19-1-prod-domain userqa]# What should I try now? Is it possible that Dovecot is having difficulty processing the attachment file? If I delete this user's mailbox file and send basic text e-mail to the user I can read/retrieve them just fine.. there only seems to be an issue when this message with its attachment arrives. The attachment seems small in size: Content-Disposition: attachment; filename="report_amex.xlsx"; size=20527; That means the attachment is 20527 bytes, correct? Thank you for any suggestions/help you can offer! Here's the message that it seems to be having issues with: Return-Path: <user(a)company.com> Received: from mxout.mailprovider.com (slb1-prod-domain.domain.net[172.19.136.4]) by cust19-1-prod-domain.domain.net (8.13.8/8.13.8) with ESMTP id qBOM8oIE029715 for <userqa_2938(a)integration.company.com>;
