       kopano-spooler.cfg - The Kopano spooler configuration file




       The spooler.cfg is a configuration file for the Kopano Spooler.  spooler.cfg contains
       instructions for the software to set up the logging system and outgoing smtp relay server.


       The file consists of one big section, but parameters can be grouped by functionality.

       The parameters are written in the form:

       name = value

       The file is line-based. Each newline-terminated line represents either a comment, nothing,
       a parameter or a directive. A line beginning with `#' is considered a comment, and will be
       ignored by Kopano. Parameter names are case sensitive. Lines beginning with `!' are

       Directives are written in the form:

       !directive [argument(s)]

       The following directives exist:

           Include and process argument

           Example: !include common.cfg


       Hostname or IP address of the outgoing SMTP server. This server needs to relay mail for
       your server.

       Default: localhost

       TCP Port number for smtp_server.

       Default: 25

       Unix socket to find the connection to the Kopano server.

       Default: file:///var/run/kopano/server.sock

       After correctly starting, the spooler process will become this user, dropping root
       privileges. Note that the log file needs to be writeable by this user, and the directory
       too to create new logfiles after logrotation. This can also be achieved by setting the
       correct group and permissions.

       Default value is empty, not changing the user after starting.

       After correctly starting, the spooler process will become this group, dropping root

       Default value is empty, not changing the group after starting.

       Write the process ID number to this file. This is used by the init.d script to correctly
       stop/restart the service.

       Default: /var/run/kopano/

       Change directory to this path when running in daemonize mode. When using the -F switch to
       run in the foreground the directory will not be changed.

       Default: /

       When a crash occurs or an assertion fails, a coredump file can be generated by the system
       for use with a crash report. For details, see the kopano-coredump(5) manpage.

       Default: systemdefault

       Use this file as key to logon to the server. This is only used when server_socket is set
       to an HTTPS transport. See the kopano-server(8) manual page on how to setup SSL keys.

       Default: value not set.

       The password of the SSL key file that is set in sslkey_file.

       Default: value not set.

       The method which should be used for logging. Valid values are:

       syslog Use the syslog service. Messages will be sent using the "mail" facility tag. See
              also journald.conf(5) or syslog.conf(5).

       file   Log to a file. The filename will be specified in log_file.

       auto   Autoselect mode: If log_file is set, that will be used.  Else, syslog will be used
              if it looks like it is available.  Else, stderr.

       Default: auto

       When logging to a file, specify the filename in this parameter. Use - (minus sign) for
       stderr output.

       Default: -

       Specify whether to prefix each log line with a timestamp in 'file' logging mode.

       Default: 1

       Buffer logging in what sized blocks. The special value 0 selects line buffering.

       Default: 0

       The level of output for logging in the range from 0 to 6. "0" means no logging, "1" for
       critical messages only, "2" for error or worse, "3" for warning or worse, "4" for notice
       or worse, "5" for info or worse, "6" debug.

       Default: 3

              Log the raw message to a file. In stage 1, not all recipients are necessarily
              resolved yet, and Bcc is still visible; this is not the exact mail that is
              delivered to the SMTP server. The file is saved to the location specified in
              log_raw_message_path. Default: no.

       Path to save the raw message to.

       Default: /var/lib/kopano


       The maximum number of threads used to send outgoing messages. For each email in the
       outgoing queue a separate thread will be started in order to allow multiple emails to be
       sent out simultaneously.

       Default: 5

       When an email is sent to a contact with a FAX type email address, the address will be
       rewritten to a normal SMTP address, using the scheme: <faxnumber>@<fax_domain>. You can
       install software in your SMTP server which handles these email addresses to actually fax
       the message to that number.


       When sending an international fax, the number will start with a '+' sign. You can rewrite
       this to the digits you need to dial when dialing to another country.

       Default: +

       Normally, a user needs to give explicit rights to other users to be able to send under
       their name. When setting this value to 'yes', the spooler will not check these
       permissions, and will always send the email with 'On behalf of' headers. Please note that
       this feature overrides 'send-as' functionality.

       Default: no

       Meeting requests will be sent using iCalendar files. This adds compatibility to more
       calendar programs. To use the previous TNEF (winmail.dat) method, set this option to

       When an email body is written in RTF text, normally this data is sent using TNEF. If you
       want to send an HTML representation of the email instead and not use TNEF, set this to

       Default: no

       Enable the Delivery Status Notifications (DSN) for users. If a user requests a DSN the
       spooler sends the request to the MTA and when the MTA support this the user will receive
       the report in the mailbox. When the MTA doesn't support DSN the user will not receive a
       report. Ensure you have a supported MTA like postfix 2.3 and higher. If DSN is disabled
       and the user request a DSN then it will be ignored and the delivery report is not sent.

       Default: yes

       Upgrades the us-ascii charset to this charset. This makes sure high-characters in
       recipients and attachment filenames are correctly sent when the body is in plain text.

       Default: windows-1252

       Normally, users are not allowed to send e-mail from a different e-mail address than their
       own. However, the 'redirect' rule sends e-mails with their original 'from' address.
       Enabling this option allows redirected e-mails to be sent with their original 'from'
       e-mail address.

       Default: yes

       This directive controls into which "Sent Items" folder(s) an e-mail message will be placed
       when sending messages. This applies to both these types of delegation:

       •   "on behalf of", where, in RFC 5322 terms, the From: line is changed, and a Sender:
           line is added.

       •   "send as", where the From: line is changed, and no Sender: line is emitted.

       Possible values are: no (message stays with delegate's "Sent Items"), yes (message is
       copied to representee's "Sent Items"), move-to-rep (message is moved from delegate to

       Some MAPI clients (such as Outlook with the Zarafa DLL) may independently retain and store
       a copy of the message into "Sent Items", unbeknownst to kopano-spooler, thereby defeating
       the effectiveness of move-to-rep.

       Default: yes

       Normally, users are not allowed to send meeting requests as external delegate. However,
       when you want to forward meeting requests you need delegate permissions. Enabling this
       option allows you to sent and forward a meeting request as a delegate Kopano and SMTP

       Default: yes

       When set to 'no', sending to the 'everyone' group is disallowed. The entire message will
       be bounced if this is attempted. When set to 'yes', this allows sending to all users in
       the 'everyone' group.

       Default: yes

       Expand groups in headers of sent e-mails. This means that the recipient of an e-mail with
       one or more groups as recipients will see the members of the groups instead of the groups
       themselves. If a group has an e-mail address, the group is not expanded irrespective of
       this setting, since having an e-mail address for the group implies that this address can
       be used to send messages to the group.

       Default: no

       Archive outgoing messages. If an archive is attached to the mailbox from which a message
       is send, the message will immediately be archived to the special Outgoing folder.

       Messages that are archived this way are not attached to the original message in the
       primary store. So there's no easy way to find the original sent item based on an archive
       or find an archive based on the sent item in the primary store. This option is only
       intended to make sure all outgoing messages are stored without the possibility for the
       owner to delete them.

       Default: no

       Enable or disable the spooler plugin framework.

       Default: yes

       The path to the spooler plugin manager.

       Default: /usr/share/kopano-spooler/python

       Path to the activated spooler plugins. This folder contains symlinks to the kopano plugins
       and custom scripts. The plugins are installed in /usr/share/kopano-spooler/python/plugins.
       To activate a plugin create a symbolic link in the plugin_path directory.


       ln -s /usr/share/kopano-spooler/python/plugins/

       Default: /var/lib/kopano/spooler/plugins

       A HTTP URL or filesystem-local socket specification for a kopano-statsd compatible web
       service that ingests service statistics such as memory usage or mail processing counters.


       Default: unix:/var/run/kopano/statsd.sock

       The time interval at which the statsd service is to be contacted, in seconds.  When
       "statsclient_url" points to a kopano-statsd instance, the value should be 60 (for now),
       because its rrdtool archives are set to expect data at this rate.

       Default: 0 (submission service is deactivated)

       This setting can be used to control SSL certificate validation.

       Default: yes


       The following options are reloadable by sending the kopano-spooler process a HUP signal:

       log_level, max_threads, archive_on_send


           The Kopano spooler configuration file.
