To set up Matrix on your domain, you'd need to do some DNS configuration.
To use an identifier like @<username>:example.com, you don't actually need
to install anything on the actual example.com server.
You do, however need to instruct the Matrix network that Matrix services for example.com are delegated
over to matrix.example.com.
As we discuss in Server Delegation, there are 2 different ways to set up such delegation:
- either by serving a
https://example.com/.well-known/matrix/serverfile (from the base domain!) - or by using a
_matrix._tcpDNS SRV record (don't confuse this with the_matrix-identity._tcpSRV record described below)
This playbook mostly discusses the well-known file method, because it's easier to manage with regard to certificates. If you decide to go with the alternative method (Server Delegation via a DNS SRV record (advanced)), please be aware that the general flow that this playbook guides you through may not match what you need to do.
| Type | Host | Priority | Weight | Port | Target |
|---|---|---|---|---|---|
| A | matrix |
- | - | - | matrix-server-IP |
| CNAME | element |
- | - | - | matrix.example.com |
Be mindful as to how long it will take for the DNS records to propagate.
If you are using Cloudflare DNS, make sure to disable the proxy and set all records to DNS only. Otherwise, fetching certificates will fail.
When you're done configuring DNS, proceed to Configuring the playbook.

When setting up a SRV record, if you are asked for a service and protocol instead of a hostname split the host value from the table where the period is. For example use service as _matrix-identity and protocol as _tcp.
As the table above illustrates, you need to create 2 subdomains (matrix.example.com and element.example.com) and point both of them to your new server's IP address (DNS A record or CNAME record is fine).
The element.example.com subdomain may be necessary, because this playbook installs the Element web client for you.
If you'd rather instruct the playbook not to install Element (matrix_client_element_enabled: false when Configuring the playbook later), feel free to skip the element.example.com DNS record.
The dimension.example.com subdomain may be necessary, because this playbook could install the Dimension integrations manager for you. Dimension installation is disabled by default, because it's only possible to install it after the other Matrix services are working (see Setting up Dimension later). If you do not wish to set up Dimension, feel free to skip the dimension.example.com DNS record.
The jitsi.example.com subdomain may be necessary, because this playbook could install the Jitsi video-conferencing platform for you. Jitsi installation is disabled by default, because it may be heavy and is not a core required component. To learn how to install it, see our Jitsi guide. If you do not wish to set up Jitsi, feel free to skip the jitsi.example.com DNS record.
The stats.example.com subdomain may be necessary, because this playbook could install Grafana and setup performance metrics for you. Grafana installation is disabled by default, it is not a core required component. To learn how to install it, see our metrics and graphs guide. If you do not wish to set up Grafana, feel free to skip the stats.example.com DNS record. It is possible to install Prometheus without installing Grafana, this would also not require the stats.example.com subdomain.
The goneb.example.com subdomain may be necessary, because this playbook could install the Go-NEB bot. The installation of Go-NEB is disabled by default, it is not a core required component. To learn how to install it, see our configuring Go-NEB guide. If you do not wish to set up Go-NEB, feel free to skip the goneb.example.com DNS record.
The sygnal.example.com subdomain may be necessary, because this playbook could install the Sygnal push gateway. The installation of Sygnal is disabled by default, it is not a core required component. To learn how to install it, see our configuring Sygnal guide. If you do not wish to set up Sygnal (you probably don't, unless you're also developing/building your own Matrix apps), feel free to skip the sygnal.example.com DNS record.
The ntfy.example.com subdomain may be necessary, because this playbook could install the ntfy UnifiedPush-compatible push notifications server. The installation of ntfy is disabled by default, it is not a core required component. To learn how to install it, see our configuring ntfy guide. If you do not wish to set up ntfy, feel free to skip the ntfy.example.com DNS record.
The etherpad.example.com subdomain may be necessary, because this playbook could install the Etherpad a highly customizable open source online editor providing collaborative editing in really real-time. The installation of Etherpad is disabled by default, it is not a core required component. To learn how to install it, see our configuring Etherpad guide. If you do not wish to set up Etherpad, feel free to skip the etherpad.example.com DNS record.
The hydrogen.example.com subdomain may be necessary, because this playbook could install the Hydrogen web client. The installation of Hydrogen is disabled by default, it is not a core required component. To learn how to install it, see our configuring Hydrogen guide. If you do not wish to set up Hydrogen, feel free to skip the hydrogen.example.com DNS record.
The cinny.example.com subdomain may be necessary, because this playbook could install the Cinny web client. The installation of Cinny is disabled by default, it is not a core required component. To learn how to install it, see our configuring Cinny guide. If you do not wish to set up Cinny, feel free to skip the cinny.example.com DNS record.
The schildichat.example.com subdomain may be necessary, because this playbook could install the SchildiChat web client. The installation of SchildiChat is disabled by default, it is not a core required component. To learn how to install it, see our configuring SchildiChat guide. If you do not wish to set up SchildiChat, feel free to skip the schildichat.example.com DNS record.
The wsproxy.example.com subdomain may be necessary, because this playbook could install the wsproxy web client. The installation of wsproxy is disabled by default, it is not a core required component. To learn how to install it, see our configuring wsproxy guide. If you do not wish to set up wsproxy, feel free to skip the wsproxy.example.com DNS record.
The buscarron.example.com subdomain may be necessary, because this playbook could install the buscarron bot. The installation of buscarron is disabled by default, it is not a core required component. To learn how to install it, see our configuring buscarron guide. If you do not wish to set up buscarron, feel free to skip the buscarron.example.com DNS record.
The rageshake.example.com subdomain may be necessary, because this playbook could install the rageshake bug report server. The installation of Rageshake is disabled by default, it is not a core required component. To learn how to install it, see our configuring Rageshake guide. If you do not wish to set up Rageshake, feel free to skip the rageshake.example.com DNS record.
To make the ma1sd Identity Server (which this playbook may optionally install for you) enable its federation features, set up an SRV record that looks like this:
- Name:
_matrix-identity._tcp(use this text as-is) - Content:
10 0 443 matrix.example.com(replaceexample.comwith your own)
This is an optional feature for the optionally-installed ma1sd service. See ma1sd's documentation for information on the privacy implications of setting up this SRV record.
Note: This _matrix-identity._tcp SRV record for the identity server is different from the _matrix._tcp that can be used for Synapse delegation. See howto-server-delegation.md for more information about delegation.
When you're done with the DNS configuration and ready to proceed, continue with Getting the playbook.
To make the postmoogle email bridge enable its email sending features, you need to configure SPF (TXT), DMARC (TXT), DKIM (TXT) and MX records
