# This file is maintained as an up-to-date snapshot of the default # homeserver.yaml configuration generated by Synapse. # # It is intended to act as a reference for the default configuration, # helping admins keep track of new options and other changes, and compare # their configs with the current default. As such, many of the actual # config values shown are placeholders. # # It is *not* intended to be copied and used as the basis for a real # homeserver.yaml. Instead, if you are starting from scratch, please generate # a fresh config using Synapse by following the instructions in INSTALL.md. # Configuration options that take a time period can be set using a number # followed by a letter. Letters have the following meanings: # s = second # m = minute # h = hour # d = day # w = week # y = year # For example, setting redaction_retention_period: 5m would remove redacted # messages from the database after 5 minutes, rather than 5 months. ################################################################################ # Configuration file for Synapse. # # This is a YAML file: see [1] for a quick introduction. Note in particular # that *indentation is important*: all the elements of a list or dictionary # should have the same indentation. # # [1] https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html ## Server ## # The public-facing domain of the server # # The server_name name will appear at the end of usernames and room addresses # created on this server. For example if the server_name was example.com, # usernames on this server would be in the format @user:example.com # # In most cases you should avoid using a matrix specific subdomain such as # matrix.example.com or synapse.example.com as the server_name for the same # reasons you wouldn't use user@email.example.com as your email address. # See https://github.com/matrix-org/synapse/blob/master/docs/delegate.md # for information on how to host Synapse on a subdomain while preserving # a clean server_name. # # The server_name cannot be changed later so it is important to # configure this correctly before you start Synapse. It should be all # lowercase and may contain an explicit port. # Examples: matrix.org, localhost:8080 # server_name: "SERVERNAME" # When running as a daemon, the file to store the pid in # pid_file: DATADIR/homeserver.pid # The absolute URL to the web client which /_matrix/client will redirect # to if 'webclient' is configured under the 'listeners' configuration. # # This option can be also set to the filesystem path to the web client # which will be served at /_matrix/client/ if 'webclient' is configured # under the 'listeners' configuration, however this is a security risk: # https://github.com/matrix-org/synapse#security-note # #web_client_location: https://riot.example.com/ # The public-facing base URL that clients use to access this HS # (not including _matrix/...).

Synapse will also # filter events received over federation so that events that should have been # purged are ignored and not stored again. # retention: # The message retention policies feature is disabled by default. Uncomment the # following line to enable it. # #enabled: true # Default retention policy. If set, Synapse will apply it to rooms that lack the # 'm.room.retention' state event. Currently, the value of 'min_lifetime' doesn't # matter much because Synapse doesn't take it into account yet. # #default_policy: # min_lifetime: 1d # max_lifetime: 1y # Retention policy limits. If set, and the state of a room contains a # 'm.room.retention' event in its state which contains a 'min_lifetime' or a # 'max_lifetime' that's out of these bounds, Synapse will cap the room's policy # to these limits when running purge jobs. # #allowed_lifetime_min: 1d #allowed_lifetime_max: 1y # Server admins can define the settings of the background jobs purging the # events which lifetime has expired under the 'purge_jobs' section. # # If no configuration is provided, a single job will be set up to delete expired # events in every room daily. # # Each job's configuration defines which range of message lifetimes the job # takes care of. For example, if 'shortest_max_lifetime' is '2d' and # 'longest_max_lifetime' is '3d', the job will handle purging expired events in # rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and # lower than or equal to 3 days. Both the minimum and the maximum value of a # range are optional, e.g. a job with no 'shortest_max_lifetime' and a # 'longest_max_lifetime' of '3d' will handle every room with a retention policy # which 'max_lifetime' is lower than or equal to three days. # # The rationale for this per-job configuration is that some rooms might have a # retention policy with a low 'max_lifetime', where history needs to be purged # of outdated messages on a more frequent basis than for the rest of the rooms # (e.g. every 12h), but not want that purge to be performed by a job that's # iterating over every room it knows, which could be heavy on the server. # # If any purge job is configured, it is strongly recommended to have at least # a single job with neither 'shortest_max_lifetime' nor 'longest_max_lifetime' # set, or one job without 'shortest_max_lifetime' and one job without # 'longest_max_lifetime' set. Otherwise some rooms might be ignored, even if # 'allowed_lifetime_min' and 'allowed_lifetime_max' are set, because capping a # room's policy to these values is done after the policies are retrieved from # Synapse's database (which is done using the range specified in a purge job's # configuration). # #purge_jobs: # - longest_max_lifetime: 3d # interval: 12h # - shortest_max_lifetime: 3d # interval: 1d # Inhibits the /requestToken endpoints from returning an error that might leak # information about whether an e-mail address is in use or not on this # homeserver. # Note that for some endpoints the error situation is the e-mail already being # used, and for others the error is entering the e-mail being unused. # If this option is enabled, instead of returning an error, these endpoints will # act as if no error happened and return a fake session ID ('sid') to clients. # #request_token_inhibit_3pid_errors: true # A list of domains that the domain portion of 'next_link' parameters # must match. # # This parameter is optionally provided by clients while requesting # validation of an email or phone number, and maps to a link that # users will be automatically redirected to after validation # succeeds.
