[Dovecot] Email address with special characters in userdb
by Arnon Weinberg 14 Oct '13

14 Oct '13

Hi, I have a userdb file set up in passwd-file format containing the following entries: >doveadm user test1*test2(a)test.com test1-test2(a)test.com test1étest2(a)test.com test1@test2@test.com test1%test2(a)test.com I can access the 1st entry (no special characters) no problem: >doveadm user test1-test2(a)test.com -f home /var/vmail The 2nd entry (using UTF-8 encoding) doesn't come up: >doveadm user test1étest2(a)test.com -f home userdb lookup: user test1étest2(a)test.com doesn't exist The 3rd entry does come up: >doveadm user test1@test2@test.com -f home /var/vmail but Postfix escapes this case using quotes, and they don't work: >doveadm user '"'test1@test2'"'@test.com userdb lookup: user "test1@test2"@test.com doesn't exist The 4th entry does not come up at all: >doveadm user test1%test2(a)test.com -f home userdb lookup: user test1%test2(a)test.com doesn't exist I believe these are all valid characters for email addresses (per the RFC) except '@' (which ironically works without escaping). How can I get them working? >dovecot --version 2.1.16 -- Arnon Weinberg www.back2front.ca

[Dovecot] LMTP Proxy auth
by claus.r＠bayern-mail.de 14 Oct '13

14 Oct '13

Hi, i tried to use lmtp proxy to a cyrus-server where i need authentication. My passdb lookup gives me: user=mailbox(a)cyrus.serv.er host=192.168.1.1 proxy=Y pass=secret destuser=cyrus_lmtp_master As i see in packettrace to the lmtp-cyrus-server the dovecot-proxy didn't try any authentication. Could someone please confirm to me that LMTP proxy with auth isn't supported or is there any configuration issue i have missed?

[Dovecot] Questions about special_use mailboxes
by Florian Lindner 14 Oct '13

14 Oct '13

Hello, I am using using dovecot 2.1.7 from debian stable: namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Spam { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } I monitor IMAP traffic using the MUA trojita. When I select the mailbox Drafts: >>> y10 SELECT Drafts (QRESYNC (1381746443 1)) <<< * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) <<< * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. Flag is \Draft instead of \Drafts? When I select Sent >>> y12 SELECT Sent (QRESYNC (1381746442 7 (2 2))) <<< * OK [CLOSED] Previous mailbox closed.␍␊ <<< * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $SENT) <<< * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $SENT \*)] Flags permitted. Why is the flag $SENT ? http://www.faqs.org/rfcs/rfc6154.html mentiones nothing like that. When I select Spam: >>> y14 SELECT Spam (QRESYNC (1381746444 1)) <<< * OK [CLOSED] Previous mailbox closed. <<< * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) <<< * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. No flag at all? Or am I getting IMAP wrong? Thanks, Florian

[Dovecot] dovecot 2.2.x and replication with dsync and shared / public namespace
by romain 13 Oct '13

Hi, I'm trying to configure replication with dsync on Dovecot 2.2.5 (and latest nightly). 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 12 Oct '13

12 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 12 Oct '13

12 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 12 Oct '13

12 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 11 Oct '13

11 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 11 Oct '13

11 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

[Dovecot] Doveadm with a 2nd Instance
by Chris Lasater 11 Oct '13

11 Oct '13

Hi Guys, I am trying to use 2 instances of Dovecot on the same server so I can have a Director managing my connections, everything appears to be working, but I can not use doveadm to control my 2nd instance, but doveconf seems to work fine. [user@server logs]$ doveconf -i Director | grep logs debug_log_path = /home/user/apps/logs/director/director_debug.log info_log_path = /home/user/apps/logs/director/director_info.log log_path = /home/user/apps/logs/director/director.log info_log_path = /home/user/apps/logs/director/director_lmtp.log [user@server logs]$ doveadm -i Director log find Debug: /home/user/apps/logs/dovecot_debug.log Info: /home/user/apps/logs/dovecot_info.log Warning: /home/user/apps/logs/dovecot.log Error: /home/user/apps/logs/dovecot.log Fatal: /home/user/apps/logs/dovecot.log I have stopped and started both my instances so the config running is what is in the config file, but when I use -i Director with doveadm it uses the other instances config. [user@server logs]$ doveadm instance list path name last used running /home/user/apps/dovecot/var/run/dovecot Dovecot 2013-09-26 00:39:14 yes /home/user/apps/dovecot/var/run/director Director 2013-09-26 00:32:31 yes Any ideas, or does anyone have any experience with the Dovecot instance feature? Chris
