[Dovecot] Dovecot 1.1.20+NFS OS changed issue
by गौरव जोशी 21 Jun '11

Hi, I am facing a wierd issue on dovecot while migrating OS of the server. I have CentOS 5.2 32bit OS , Dovecot 1.1.20 with NFS on the server. When I am migrating it to CenOS 5.6 32bit with same Dovecot version. I compiled the same version i.e. 1.1.20 again. Now when I check the number of connection on this new server I can see only 8-10 connections for IMAP and 8-10 for POP3, where on old server I can still see the number of connections crosses 500+. I checked system level configuration which I found identical, limits set to same as old server, still no change in number of connections. I even tried the above exercise on CentOS 5.6 64bit version. again the result is same. I have tried all the changes/configurations I could think of. Can you please help me to sort out this issue? dovecot -n output ; ============================================= # 1.1.20: /usr/local/etc/dovecot.conf # OS: Linux 2.6.28 i686 CentOS release 5.6 (Final) syslog_facility: local0 protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Welcome to MailServe Popserver. login_process_per_connection: no max_mail_processes: 800 mail_max_userip_connections(default): 150 mail_max_userip_connections(imap): 150 mail_max_userip_connections(pop3): 300 verbose_proctitle: yes first_valid_uid: 99 first_valid_gid: 99 mail_location: maildir:~/Maildir:INDEX=/indexes/%h:CONTROL=/indexes/%h mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_no_flag_updates(default): no pop3_no_flag_updates(imap): no pop3_no_flag_updates(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls lda: postmaster_address: postmaster(a)example.com mail_plugins: cmusieve quota mail_log mail_plugin_dir: /usr/local/lib/dovecot/lda log_path: /var/log/dovecot-deliver.log auth_socket_path: /var/run/dovecot/auth-master auth default: worker_max_count: 5 passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: nobody group: nobody master: path: /var/run/dovecot/auth-master mode: 384 user: nobody group: nobody ============================================= Have a nice time, Gourav Joshi Have a look at www.linuxquestions.in

[Dovecot] dovecot-metadata-8 released
by Dennis Schridde 20 Jun '11

20 Jun '11

Hello everyone! I just released dovecot-metadata-8, which is an implementation of RFC 5464 (IMAP METADATA), allowing to add comments/annotations/metadata to folders of an email account. The major feature is that it works with Akonadi, or more specifically the Kolab backend thereof, while being dovecot-2.0 compatible. The module consists of 3 plugins, two IMAP frontends and one backend: * "imap-annotatemore" is a partial implementation of draft-daboo-imap- annotatemore-08 (early predecessor to RFC 5464), based on work by Bernhard Herzog (Intevation GmbH). The sole intention is to support Kolab, not to strictly implement the draft. * "imap-metadata" is a complete implementation of RFC 5464. Kolab clients do not (yet) use these commands. * "metadata" is the common backend imap-metadata and metadata were entirely written from scratch, while imap- annotatemore is an adaption of the work by Bernhard Herzog to the new backend. You can download the code via Hg [1] or as exported tarball [2] from the Hg webinterface. Please note that the README is outdated, as are some other files. The build process is pretty much straightforward, just make sure you have the dovecot headers available on your system: ./autogen.sh ./configure --with-dovecot=/path/to/dovecot make make install Next you need to adjust your dovecot config. The following works for me: == dovecot.conf == dict { metadata = file:/var/lib/dovecot/shared-metadata } == 10-mail.conf == mail_plugins = ... metadata == 20-imap.conf == protocol imap { mail_plugins = $mail_plugins ... imap_metadata imap_annotatemore } == 90-plugin.conf == plugin { metadata_dict = proxy::metadata } To allow a Kolab client to find (e.g.) the addressbook folder, issue this IMAP command after login: SETMETADATA "path/to/folder" ("/shared/vendor/kolab/folder-type" "contact") If you find any bugs (crashes, incompatibilities with RFC 5464, etc), please write me a mail. Be advised that this code is still experimental and might crash your server! @Timo: Please have a look at the src/*-ext.[ch] files, they contain extensions to the dovecot libraries and might be useful for others, too. Kind regards, Dennis Schridde [1] http://hg.dovecot.org/dovecot-metadata-plugin [2] http://hg.dovecot.org/dovecot-metadata-plugin/archive/bdf2445e101f.tar.gz

[Dovecot] Gmail like virtual mailboxes
by Aleve Sicofante 19 Jun '11

19 Jun '11

I'm new to this list so let me introduce myself: I'm a computer literate user (I've done some C programming long ago and can run a Linux system and do some light admin), I've never installed a mail server before and I'm in the process of migrating my family and my small business from Gmail (Google Apps) to a virtual server mainly for privacy reasons. I'm in love with Gmail's label system and I just plain hate traditional folders. I use hierarchical labels (as if they were folders but with a message belonging to many at the same time) and that MUST be preserved in the migration. I've looked at Courier's IMAP keywords implementation and it looks good, but everyone on the internet is recommending Dovecot, so here I am. I've tried hard to find information about using unlimited hierarchical labels, virtual mailboxes or any other way of mimicing Gmail's functionality with Dovecot, but I'm lost. First of all: can it be done? If so, is there any introductory documentation? (I've only found very sparse information.) Is it available for any storage format (mbox, maildir, dbox)? Any help will be very appreciated. -- Aleve Sicofante
