[Dovecot] (Maybe stupid) question about selecting mailbox
by kjonca＠o2.pl 05 Nov '13

05 Nov '13

Does mailbox with "\NoSelect" can be select or examine?

Re: [Dovecot] Doveadm with a 2nd Instance
by Chris Lasater 03 Nov '13

03 Nov '13

While testing some more I found out something else. I have an alias set for doveadm so it was running with sudo and that ended up being part of the issue. If doveadm is run as a regular user then the problem goes away [user@server ~]$ doveadm -i Director log find Debug: /home/user/apps/logs/director/director_debug.log Info: /home/user/apps/logs/director/director_info.log Warning: /home/user/apps/logs/director/director.log Error: /home/user/apps/logs/director/director.log Fatal: /home/user/apps/logs/director/director.log [user@server ~]$ sudo 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 Also if I run "sudo doveadm stop" to stop the main instance, I now have the ability to use the -i Director using sudo. Unfortunately this makes it difficult to manage two instances. Does anyone have an idea of getting this to work with sudo? Chris

[Dovecot] When imapc can't connect to remote IMAP prevents user login (and blocks LDA)

[Dovecot] fts-solr indexer-worker connects to wrong solr host dovecot-2.2.4

Hello. We're setting up fts solr and want to have the solr server host be set per-user via UserDB.

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] Doveadm with a 2nd Instance
by Chris Lasater 12 Oct '13

12 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?

[Dovecot] SSL with startssl.com certificates
by Dan Langille 11 Oct '13

11 Oct '13

I'm using Dovecot 2.2.5. I'm setting up and new IMAPS server for personal use (i.e. only me). I have success with self-signed certificates but not with others (e.g. StartSSL.com) With StartSSL certs: I've been able to connect and test commands via: openssl s_client -connect imaps.unixathome.org:993 Can you configure your iPhone or Macbook to access the above? Authentication isn't the issue. Connection is the issue. I've been able to get Thunderbird to connect and access my mail. However, I've been unable to get my iPhone or my Mac configured to use the same IMAP server. On the iPhone, adding the new Mail account causes the Settings app to crash on a persistently consistent basis when adding the new account. The crash occurs when connecting to the IMAPS server. Configuration never completes. I suspect the problem is SSL because in both cases (iPhone and Mac), I see these messages I see in the logs: *** /var/log/debug.log *** Sep 13 11:50:32 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: auth: Debug: auth client connected (pid=31647) Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv2/v3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [166.137.84.11] Sep 13 11:50:45 imaps dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [166.137.84.11] *** /var/log/maillog *** Sep 13 11:50:46 imaps dovecot: imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [166.137.84.11] Sep 13 11:50:46 imaps dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=166.137.84.11, lip=199.233.228.197, TLS handshaking: Disconnected, session=<a7AJd0LmWwCmiVQL> /usr/local/etc/ssl/imaps.unixathome.org.crt contains only the cert issued by StartSSL /usr/local/etc/ssl/imaps.unixathome.org.nopassword.key contains a no-password key generated by myself.
