# 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 file for Synapse. # # This is a YAML file: see [1] for a quick introduction.

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.

If set, a user won't be able to send a # 'm.room.retention' event which features a 'min_lifetime' or a 'max_lifetime' # that's not within this range.

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is that some rooms might have a # retention policy with a low 'max_lifetime', where history needs to be purged # of outdated messages on a more frequent basis than for the rest of the rooms # (e.g. every 12h), but not want that purge to be performed by a job that's # iterating over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. # #purge_jobs: # - shortest_max_lifetime: 1d # longest_max_lifetime: 3d # interval: 12h # - shortest_max_lifetime: 3d # longest_max_lifetime: 1y # interval: 1d ## TLS ## # PEM-encoded X509 certificate for TLS. # This certificate, as of Synapse 1.0, will need to be a valid and verifiable # certificate, signed by a recognised Certificate Authority. # # See 'ACME support' below to enable auto-provisioning this certificate via # Let's Encrypt. # # If supplying your own, be sure to use a `.pem` file that includes the # full certificate chain including any intermediate certificates (for # instance, if using certbot, use `fullchain.pem` as your certificate, # not `cert.pem`). # #tls_certificate_path: "CONFDIR/SERVERNAME.tls.crt" # PEM-encoded private key for TLS # #tls_private_key_path: "CONFDIR/SERVERNAME.tls.key" # Whether to verify TLS server certificates for outbound federation requests. # # Defaults to `true`.

Configurable to `1`, `1.1`, `1.2`, or `1.3`.

For more info, and alternative solutions, see # https://github.com/matrix-org/synapse/blob/master/docs/ACME.md#deprecation-of-acme-v1 # # Note that provisioning a certificate in this way requires port 80 to be # routed to Synapse so that it can complete the http-01 ACME challenge. # By default, if you enable ACME support, Synapse will attempt to listen on # port 80 for incoming http-01 challenges - however, this will likely fail # with 'Permission denied' or a similar error. # # There are a couple of potential solutions to this: # # * If you already have an Apache, Nginx, or similar listening on port 80, # you can configure Synapse to use an alternate port, and have your web # server forward the requests. For example, assuming you set 'port: 8009' # below, on Apache, you would write: # # ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge # # * Alternatively, you can use something like `authbind` to give Synapse # permission to listen on port 80. # acme: # ACME support is disabled by default.

So if federation traffic is handled directly by synapse # then no modification to the list is required. # # If synapse is run behind a load balancer that handles the TLS then it # will be necessary to add the fingerprints of the certificates used by # the loadbalancers to this list if they are different to the one # synapse is using. # # Homeservers are permitted to cache the list of TLS fingerprints # returned in the key responses up to the "valid_until_ts" returned in # key.
