Choosing your server name
It is important to choose the name for your server before you install Synapse, because it cannot be changed later.
The server name determines the "domain" part of user-ids for users on your
server: these will all be of the format @user:my.domain.name. It also
determines how other matrix servers will reach yours for federation.
For a test configuration, set this to the hostname of your server. For a more
production-ready setup, you will probably want to specify your domain
(example.com) rather than a matrix-specific hostname here (in the same way
that your email address is probably user@example.com rather than
user@email.example.com) - but doing so may require more advanced setup: see
Setting up Federation.
