server_bind¶

Bind to a particular IP address. Leave empty to bind to all addresses.

Default: (empty)

server_socket¶

Unix socket to find the connection to the Kopano server.

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

run_as_user¶

After correctly starting, the dagent 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.

run_as_group¶

After correctly starting, the dagent process will become this group, dropping root privileges.

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

pid_file¶

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/dagent.pid

coredump_enabled¶

When a crash occurs or an assertion fails, a coredump file can be generated. This file should be sent along with the crash report. It is turned on by default in Kopano, but your system may have it disabled. For details, see the kopano-coredump(5) manpage.

sslkey_file¶

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.

sslkey_pass¶

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

Default: value not set.

lmtp_port¶

Port to listen to for LMTP requests

Default: 2003

lmtp_max_threads¶

The maximum number of LMTP threads that can be running simultaneously. This is also limited by your SMTP server. (20 is the postfix default concurrency limit)

Default: 20

spam_header_name¶

To detect if the receiving mail is spam, the DAgent can check this header for a value that is in there. This name is case insensitive. If this option is empty, the detection method will be turned off. You can also force a delivery to the Junk Mail folder using the -j commandline option.

Default: X-Spam-Status

spam_header_value¶

When this value is found in the spam_header_name, the mail will be considered spam, and will be delivered in the user's Junk Mail folder. The value can be anywhere in the header, not just the start. The value is case insensitive.

Default: Yes,

log_method¶

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

syslog

Use the Linux system log. All messages will be written to the mail facility. See also syslog.conf(5).

file

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

Default: file

log_file¶

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

Default: /var/log/kopano/dagent.log

log_timestamp¶

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

Default: 1

log_buffer_size¶

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

Default: 0

log_level¶

The level of output for logging in the range from 0 to 5. 0 means no logging, 5 means full logging.

Default: 2

log_raw_message¶

Log the raw message to a file. The file is saved to the location specified in log_raw_message_path.

Default: no

log_raw_message_path¶

Path to save the raw message.

Default: /tmp

archive_on_delivery¶

Archive incoming message on delivery. If an archive is attached to the target mailbox, the message will immediately be archived upon delivery.

Rules will be processed before the message is archived, so when a rule moves the message to an alternate location, the archived message will be placed in the correct location in the archive. When the incoming message is copied by a rule, only the original message is archived.

Default: no

mr_autoaccepter¶

Kopano-dagent can auto-accept meeting requests if the mr-accept option is enabled for a user. When this option is enabled and a meeting request or meeting cancellation is received, this script is started with the following parameters: /usr/sbin/kopano-mr-accept <username> </path/to/dagent.cfg> [<ENTRYID>].

If the script is successful (exitcode is 0), then no other actions are performed (eg rules or vacation messages) and the message is not delivered in the inbox. If the script exits with a non-zero exit code, rules and vacation messages are run as usual, and the message is delivered in the inbox (or other folder, depending on rules or options).

Default: /usr/sbin/kopano-mr-accept

mr_autoprocessor¶

Kopano-dagent can auto-process meeting requests. When this is enabled and a meeting request, response or meeting cancellation is received, this script is started with the following parameters: /usr/bin/kopano-mr-process <username> </path/to/dagent.cfg> [<ENTRYID>].

Default: /usr/bin/kopano-mr-process

autoresponder¶

Kopano-dagent invokes the autoresponder to send out-of-office replies. You can configure a custom autoresponder using this configuration option.

Default: /usr/sbin/kopano-autorespond

plugin_enabled¶

Enable or disable the dagent plugin framework.

Default: yes

plugin_manager_path¶

The path to the dagent plugin manager.

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

plugin_path¶

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

Example:

ln -s /usr/share/kopano-dagent/python/plugins/BMP2PNG.py /var/lib/kopano/dagent/plugins/BMP2PNG.py

Default: /var/lib/kopano/dagent/plugins

default_charset¶

Some emails do not contain any charset information or specify us-ascii even though it isn't. In both cases, dagent will assume the following charset is used. Note that this implies that the given charset should be a superset of us-ascii (most charsets are).

Default: iso-8859-15

set_rule_headers¶

Enable the addition of X-Kopano-Rule-Action headers on messages that have been forwarded or replied by a rule.

Default: yes

no_double_forward¶

Enable this option to prevent rules to cause a loop. An e-mail can only be forwarded once. When this option is enabled, the set_rule_headers option must also be enabled.

Default: no

forward_whitelist_domains¶

A list of space-separated domains to which forwarding via a rule is allowed. The "*" matches zero or more characters (including dots, i.e. subdomains at multiple levels). Do not use "*kopano.com" to permit both "@kopano.com" and "@sub.kopano.com", as that would also allow "@notkopano.com".

Default: *

forward_whitelist_domain_subject¶

A custom-defined reply subject to the user with a rule forwarding to a domain not in forward_whitelist_domains.

Default: REJECT: %subject not forwarded (administratively blocked)

forward_whitelist_domain_message¶

A custom-defined reply message to the user with a rule forwarding to a
domain not in forward_whitelist_domains.

Default: The Kopano mail system has rejected your request to forward your e-mail with subject %subject (via mail filters) to %sender: the operation is not permitted.\n\nRemove the rule or contact your administrator about the forward_whitelist_domains setting.

unknown_charset_substitution¶

A space-separated list of pairs of space-separated charset name and replacement to use when encountering mail bodies with unrecognized character set encodings. This is a lossy operation; its use is not recommended. Normally, dagent would store such mail bodies as attachments to preserve their content, with decoding left to the user who can try any number of encodings, not just one.
