"A host in Prosody is a domain on which user accounts can be created. For
|
||
example if you want your users to have addresses like
|
||
@samp{\"john.smith@@example.com\"} then you need to add a host
|
||
@samp{\"example.com\"}. All options in this list will apply only to this host.
|
||
|
||
Note: the name \"virtual\" host is used in configuration to avoid confusion with
|
||
the actual physical host that Prosody is installed on. A single Prosody
|
||
instance can serve many domains, each one defined as a VirtualHost entry in
|
||
Prosody's configuration. Conversely a server that hosts a single domain would
|
||
have just one VirtualHost entry.
