Mailman3 Core

Learn about configurations >

• aliases_map | string

  Map various aliases to existing mailing lists. e.g. also-my-list@lists.local my-list@lists.local

• enable_spamassassin | boolean

  Default: True

  Enable Spamassassin mail filter

• enable_spf | boolean

  Default: True

  Enable Postfix SPF extensions

• enable_strict_host_checks | string

  Enable strict hostname checks in smtpd_recipient_restrictions.

  Set to "true" to enable, or "test" to enable checks in test mode.

  Test mode will prefix the restrictions with warn_if_reject, so that potential rejections will appear in the server logs but won't actually reject messages.

• extra_packages | string

  Space separated list of extra deb packages to install.

• hostname | string

  Use specified hostname/mailname.

• install_keys | string

  List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.

• install_sources | string

  List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.

• nagios_context | string

  Default: juju

  Used by the nrpe subordinate charms. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup

• package_status | string

  Default: install

  The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".

• sa_http_proxy | string

  Define a http(s) proxy in /etc/default/spamassassin

  This will add http_proxy and https_proxy environment variables in Spamassassin's /etc/default file and allow sa-update cronjob to update rulesets though a http(s)_proxy.

  A valid entry would be http://proxy.host.name:3128

• site_owner | string

  Default: admin@changeme.internal

  E-mail used by mailman for e-mail verifications etc.

• spamassassin_policy | string

  Custom Spamassassin policies

• spf_config | string

  Default: debugLevel = 1 defaultSeedOnly = 1 HELO_reject = SPF_Not_Pass Mail_From_reject = Fail PermError_reject = False TempError_Defer = False skip_addresses = 127.0.0.0/8,::ffff:127.0.0.0/104,::1/128

  Custom SPF configuration
