[Dovecot] Mailboxes separated from IMAP server
by Reymer Antonio Vargas Solano 21 Oct '13

21 Oct '13

Hello folks, At my university we are trying to implement a distributed email backend, but I have some troubles, The topology: Server A: Postfix+LMTP # MTA Server B: Dovecot+LMTP # Just mailboxes Server C: Dovecot # POP3/IMAP Right now the Server A can leave a received email to the Server B, but I don't know how to communicate Server C to the Server B to retrieve the emails. I think that we should use IMAP protocol, but I am confused about how to connect them, I don't know if we have to use a proxy IMAP server, or another thing. Can anyone give me an idea? Regards, Reymer Antonio Vargas Solano

[Dovecot] Upgrade from 2.1 to 2.2 on Debian
by Lucas Rothamel - Eye Catching Webdesign 21 Oct '13

21 Oct '13

Hello, I am currently running Dovecot 2.1 on current Debian and need to upgrade to 2.2 to use the replication features. I understand that I therefore need to compile Dovecot myself. I am using a MySQL database for users authentication, therefore I need to compile Dovecot with mysql support: *./configure --with-mysql* Unfortunately this terminates with: *configure: error: Can't build with MySQL support: libmysqlclient not found* I installed libmysqlclient from debian repos, but it does not help. Also, how do I then connect the newly installed dovecot to my existing /etc/init.d/dovecot script? Thank you.

[Dovecot] patch for ssl_prefer_server_ciphers in dovecot 2.1
by Adi Kriegisch 20 Oct '13

20 Oct '13

Dear all, I tried to do a backport of 'ssl_prefer_server_ciphers' (http://hg.dovecot.org/dovecot-2.2/rev/897484f45a87/) to Dovecot 2.1 (namely the Debian version of Dovecot) and wanted to ask if there is any chance to integrate this feature into Dovecot 2.1 'upstream' as well. As the code structure changed quite a bit, I am not sure if my patch is complete. I tested it with pop3s and imaps in my test environment and it works just as expected and seemed to not have any unwanted effects. (Dovecot code is probably the most beautiful and easy to read C code I've seen, but there might also be some pitfalls I missed.) best regards, Adi Kriegisch PS: I need that feature to enable PFS while allowing Outlook to still connect and the others not to fall back to a different cipher; I was unable to find a PFS cipher that is supported by Outlook and OpenSSL.

[Dovecot] Issues with configure script / Makefile
by Bret Jordan 19 Oct '13

19 Oct '13

Dear Dovecot, I have noticed that when you pass a --prefix in to the configure script and say specify a path of /local/dovecot-2.2.6 that when you install most of the subdirectories (etc, lib, include, libexec,etc) have a dovecot directory in them, like if you were installing to /. This is not typical of most *nix software. So I tried to specify the exact location with the following configure options, but they are not honored when it comes to installation. I have looked through the configure script to see if I can see where the problem is and can not see it. These are the ones that do not work. Some of the others, however to work. # Do not work --sysconfdir=/local/dovecot-2.2.6/etc \ --libdir=/local/dovecot-2.2.6/lib \ --includedir=/local/dovecot-2.2.6/include \ --libexecdir=/local/dovecot-2.2.6/libexec \ # Do work --docdir=/local/dovecot-2.2.6/share/doc \ --with-ssl=openssl --with-ssldir=/local/dovecot.2.2.6/ssl \ --with-statedir=/local/dovecot-2.2.6/lib \ --with-moduledir=/local/dovecot-2.2.6/lib \ --with-rundir=/run/dovecot Bret Bret Jordan CISSP | Sr Security Architect PGP Fingerprint: 62A6 5999 0F7D 0D61 4C66 D59C 2DB5 111D 63BC A303 "Without cryptography vihv vivc ce xhrnrw, however, the only thing that can not be unscrambled is an egg."

This is an urgent problem for us. Is this expected? the problem is that when users access their e-mail through web-mail (roundcubemail) users see each others messages in unified "Sent" folder We have used: joe /etc/postfix/virtual to enable managing e-mails on multiple domains by same Postfix server.

[Dovecot] Public dovecot namespace visible only to some users
by Joachim Breitner 17 Oct '13

17 Oct '13

Hi, I have a dovecot IMAP server (version 2.1.7) with Maildirs and a virtual user setup (e.g. all accounts are mapped to the same system user). I’d like to create a public namespace shared between users A and B, but not any other user. I tried to set up the namespace as follows: namespace { type = public separator = . prefix = INBOX.XFeeds. location = maildir:/var/vhosts/feeds:INDEX=~/Maildir/feeds/ subscriptions = no } together with a acl-file: /var/vhosts/feeds $ cat dovecot-acl user=A lrwstipekxa user=B lrwipk Now user C cannot access the contents of the XFeeds mailbox, but it still shows up in its IMAP client. How can I make sure that other users cannot observe that this namespace exists?

[Dovecot] Using dovecot as LDA for postfix
by Farzad Mahdikhani 15 Oct '13

15 Oct '13

Hi Here is my environment: Red Hat Enterprise Linux Server release 5.7 (Tikanga) postfix-2.9.1-1.rhel5 dovecot 1.0.7 I want to config a complete postfix-dovecot mail server. First I configured postfix to use procmail, its default LDA and dovecot for pop3 and imap. I didn't changed main.cf a lot, just myhostname and a few other properties. I didn't set home_mailbox. About dovecot.conf here is the output of dovecot -n : # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd As you can see mail_location is not set. At this time everything was OK and working. I was able to send email using SquirrelMail and thunderbird. I got two users, user1 and user2, in my linux machine and when I sent an email from user1(a)software.com to user2(a)software.com the sent mail was saved in /home/user1/mail/Sent and the received email was in /var/mail/user2. The log file for dovecot had entries like this for user1 and user2: dovecot: Oct 14 14:44:52 Info: IMAP(user1): maildir: couldn't find root dir dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root exists (/home/user1/mail) dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1) dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1 At this point I tried to change the LDA from procmail to dovecot by the following settings: I added/changed the following in the main.cf: mailbox_command = /usr/libexec/dovecot/deliver dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = software.com virtual_transport = dovecot I added the following in the master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient} But it didn't work. When I send email from from user2 to user1 the sent email is correctly saved in /home/user2/mail/Sent but it seems that user1 doesn't receive the incoming email. dovecot.log had entries like the following: dovecot: Oct 14 14:54:04 Info: imap-login: Login: user=<user1>, method=PLAIN, rip=::ffff:172.27.7.8, lip=::ffff:172.16.100.183, TLS dovecot: Oct 14 14:54:04 Info: IMAP(user1): Effective uid=504, gid=504, home=/home/user1 dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: access(/home/user1/Maildir, rwx): failed: No such file or directory dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: couldn't find root dir dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root exists (/home/user1/mail) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1) dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1 Setting home_mailbox = Maildir/ in main.cf and mail_location = maildir:~/Maildir in dovecot.cf didn't help. I have been googling and reading and testing for 4 or 5 days for this but there was no chance. Now, I am stuck and any help would be really really appreciated. Regards, Ferez

[Dovecot] how to handle logging
by Andreas Schulze 15 Oct '13

15 Oct '13

Hello, I plan a migration to dovecot and have concerns about the amount of logged data. On a testsystem dovecot produced 1TB syslog per day with a comparable amount of pop3 sessions. The current server log to STDOUT which is connected to multilog (circular buffer, http://cr.yp.to/daemontools/multilog.html) That way I can have a look at the last activities to any time. I like to have that in dovecot too. But since dovecot uses syslog it's not possible to adopt 1:1 Any ideas?

[Dovecot] POP3 Setup help - more info
by Thomas I Higgins 15 Oct '13

15 Oct '13

Well my last email went unaswered - I assume because I didn't provide enough detailed information. Not a surprise if that is the case. Anyway, I also noted that there is no dovecot/pop3 process like there is for IMAP. Not certain that is wrong, but I am guessing it is. I am enclosing the output from a doveconf -an query - hopefully you can see a screenshot, otherwise I have to figure out how to get it in text form (work disables cp & scp traffic). Hopefully this will provide information that will help define what I am missing? Thanks again, Thomas Higgins

[Dovecot] Analyzing and correlating Dovecot with Postfix logs
by Igor David 14 Oct '13

14 Oct '13

Hi All, I was wondering if anyone knows what are best practices for correlating logs between Postfix and Dovecot ? I am having setup with postfix + amavisd + spamassassin + dovecot and everything looks like a charm for few years now. However, when e-mail arrives to my system, postfix is sending it to amavisd on port 10024, which is returning back to postfix on 10025, and postfix is then delivering e-mail to Dovecot (which is acting as LDA), so I can find e-mail header via message-ID easily in Postfix logs. But after that I cannot find e-mail in my Dovecot Maildir list as a filename, as Dovecot is having it's own way of storing e-mails in Maildir format, and I can't see that messageID in directory. I can grep all e-mails which can take some time, so I was wondering if there is more appropriate work around or setup Postfix/Dovecot, e.g. to modify somehow dovecot Maildir naming convention or similar? I was trying to find answer around but could not so any help is appreciated! Versions: Dovecot: 2.1.13 Amavisd: amavisd-new-2.6.6 postfix: 2.3.3 Thanks in advance! -- Kind regards, Igor

[Dovecot] Email address with special characters in userdb

[Dovecot] Questions about special_use mailboxes

I did followed the guide at http://wiki2.dovecot.org/Replication But I can get dsync-server working only if my users do not have access to shared mailboxes and / or public mailboxes which is problematic for our setup. dsync-server is trying to create folders in public/ namespace : ------------------------------------- 2013-09-23 20:34:04 dsync-server(adupont): Panic: file dsync-brain-mailbox-tree.c: line 384 (dsync_brain_mailbox_tree_add_delete): assertion failed: (other_node->ns == NULL || other_node->ns == node->ns) 2013-09-23 20:34:04 dsync-server(adupont): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x64faa) [0x7f7bf42dcfaa] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x64fee) [0x7f7bf42dcfee] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f7bf4299299] -> dovecot/doveadm-server() [0x41ba52] -> dovecot/doveadm-server(dsync_brain_recv_mailbox_tree_deletes+0xbb) [0x41c39b] -> dovecot/doveadm-server(dsync_brain_run+0x37c) [0x41972c] -> dovecot/doveadm-server() [0x419bf8] -> dovecot/doveadm-server() [0x42ba20] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f7bf42ed3d6] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xaf) [0x7f7bf42ee23f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f7bf42ecf18] -> dovecot/doveadm-server() [0x416e59] -> dovecot/doveadm-server() [0x40cc77] -> dovecot/doveadm-server() [0x415ddd] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f7bf42ed3d6] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xaf) [0x7f7bf42ee23f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f7bf42ecf18] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f7bf429e553] -> dovecot/doveadm-server(main+0x11b) [0x40c9eb] -> /lib64/libc.so.6(__libc_start_main+0xed) [0x7f7bf3f0932d] -> dovecot/doveadm-server() [0x40ca59] 2013-09-23 20:34:04 dsync-server(adupont): Fatal: master: service(doveadm): child 28131 killed with signal 6 (core dumped) ------------------------------------- dsync-server is trying to create folders in shared/ namespace : ------------------------------------- 2013-09-23 20:34:05 dsync-server(s.durant): Panic: file dsync-mailbox-tree-sync.c: line 1029 (sync_create_mailboxes): assertion failed: (node->ns == other_node->ns) 2013-09-23 20:34:05 dsync-server(s.durant): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x64faa) [0x7ffb6fd74faa] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x64fee) [0x7ffb6fd74fee] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7ffb6fd31299] -> dovecot/doveadm-server() [0x426025] -> dovecot/doveadm-server(dsync_mailbox_trees_sync_init+0x139) [0x427789] -> dovecot/doveadm-server(dsync_brain_recv_mailbox_tree_deletes+0xdd) [0x41c3bd] -> dovecot/doveadm-server(dsync_brain_run+0x37c) [0x41972c] -> dovecot/doveadm-server() [0x419bf8] -> dovecot/doveadm-server() [0x42ba20] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7ffb6fd853d6] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xaf) [0x7ffb6fd8623f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7ffb6fd84f18] -> dovecot/doveadm-server() [0x416e59] -> dovecot/doveadm-server() [0x40cc77] -> dovecot/doveadm-server() [0x415ddd] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7ffb6fd853d6] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xaf) [0x7ffb6fd8623f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7ffb6fd84f18] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7ffb6fd36553] -> dovecot/doveadm-server(main+0x11b) [0x40c9eb] -> /lib64/libc.so.6(__libc_start_main+0xed) [0x7ffb6f9a132d] -> dovecot/doveadm-server() [0x40ca59] 2013-09-23 20:34:05 dsync-server(s.durant): Fatal: master: service(doveadm): child 28137 killed with signal 6 (core dumped) ------------------------------------- If I run the command "doveadm -v sync -u my.user -f tcp:10.20.0.2:12345" mailboxes are sync correctly.

[Dovecot] Problem with PAM, vpopmail and Roundcube
by ede＠ede.com.ec 13 Oct '13

13 Oct '13

Hello, I have a problem to which I have not been able to find a solution by myself or online. I have Dovecot running together with Qmail on a CentOS server. I need to be able to control which users are allowed IMAP access and at the same time allow IMAP access for all users when the requests are coming from a specific IP. My problem has two parts, detailed below. ----------------------------------------------------------- 1. PAM not working to allow access only for specified users ----------------------------------------------------------- Right now I am controlling IMAP access with [vmoduser -i] in Qmail which is not what I want. I need the IMAP access to be closed for everyone and then specify which users are allowed to access. I tried using [pam.d] for this as per http://wiki.dovecot.org/Authentication/RestrictAccess but although I am not getting any errors, all users are still allowed access unless I block them with [vmoduser -i]. In [dovecot.conf] I have: passdb pam { args = * } In [/etc/pam.d/imap] I have: auth required pam_listfile.so item=user sense=allow file=/etc/imapusers onerr=fail And in [/etc/imapusers] I have specified the only users that should have access. Any ideas why this isn't working? ------------------------------------------------------- 2. Allow access for all users coming from a specific IP ------------------------------------------------------- I have a Roundcube installation running on an external server and I need *all* my users to be able to use the Webmail regardless if they have IMAP or only POP access from their computer or mobile devices. Using PAM I tried in [/etc/pam.d/imap]: auth required pam_listfile.so item=user sense=allow file=/etc/imapusers onerr=fail allow_nets=127.0.0.0/8,192.168.0.0/16,1.2.3.4 ...where the webmail installation would be installed at IP [1.2.3.4]. But no luck! ------------------------------------------------------- Please - if there are anyone with ideas I could really use them. I have been going around in circles for the last couple of weeks and I don't know what to do! Sincerely, Daniel

[Dovecot] Problem with Dovecot after upgrade to Debian 7.0 (stable)
by Milan Milošević 13 Oct '13

13 Oct '13

Dear all, few days ago I updated Debian to the latest stable and since then Dovecot is not working. I use Dovecot as LDA for Postfix and also for IMAP access. Also I used SASL and everything was ok before update. After I updated to Dovecot 2.1.7 (it used to be 1.x before) it looks like that e-mail delever is working but I can not configure IMAP access to work. All users/passwords are stored as local users in /etc/passwd When I tried to connect to imap log file shows: Oct 12 22:16:16 seenet-mtp dovecot: auth-worker(24788): Debug: pam(user(a)mydomain.com,178.x.y.z): lookup service=dovecot Oct 12 22:17:16 seenet-mtp dovecot: auth: Error: auth worker: Aborted request: Lookup timed out Also tested access opensasl clent and after I tried to log in I have received: * OK Waiting for authentication process to respond.. tar NO [UNAVAILABLE] Temporary authentication failure.

[Dovecot] Transparent Migration from cyrus to dovecot
by Jogi Hofmüller 13 Oct '13

13 Oct '13

Hi dovecot people, We are in the process of preparing the migration from a cyrus 2.1 installation to dovecot. Dovecot will be installed on new hardware, so we have separated servers that can/will exist in parallel for a while. Our goal is to do the migration without interrupting the service for our users too much. Currently we tend to using dsync. So I am asking for best practice suggestions, tips and hints from people who have done such a thing before. Curiously awaiting your replies ;) Cheers! PS: I am subscribed to the list. So no need to include my address in replies. Thanks! -- j.hofmüller Optimism doesn't alter the laws of physics. - Subcommander T'Pol

[Dovecot] Dovecot 2.2.6 comression library build error
by Dimitri 12 Oct '13

12 Oct '13

Hi, I'm trying to build Dovecot 2.2.6 under Mageia Linux, and there are two issues. 1. I get the following errors during build, please see http://pastebin.com/RmSRZPip - the compression library requires dlopen/dlsym/etc functions, but the library providing them is not mentioned in the linking command. I've managed to workaround this by adding -ldl to the corresponding src/lib-compression/Makefile.in line. 2. The lib90_sieve_extprograms_plugin.so library gets installed into <libdir>/dovecot/sieve (and it's the only file to reside there), while all other modules are installed into <libdir>/dovecot/modules. Has this been done on purpose? For Mageia package, I've decided to move this file to the standard location. Thanks, Dimitri Mageia Linux packager

by voytek＠sbt.net.au 12 Oct '13

12 Oct '13

dovecot 2.1.1 I access my IMAP folders through SquirrelMail as a result of 'part copying' (probably through web client ? not sure), that is copying/moving some emails, later, the rest, I have a sub folder where I have maybe 30 emails from 2012 appear at the very end like so 2013/2012/2010/.../2006/2005/2012 how can I re-sort ? thanks Voytek
