Its parts and their meaning are described in the following table:
The name of the host. It is determined automatically, unless set using
hostnameconfiguration file statement (see hostname directive).
Arbitrary text, as set via
initial-banner-textconfiguration statement (see initial-banner-text).
A comma-separated list of server capabilities. It is configured using
capabilitystatement (see Capabilities).
A unique identifier similar to the format specified in RFC822, except that spaces and quoted pairs are not allowed within it.
This identifier will be used by the client when formulating the authentication string used in the
AUTHcommand (see AUTH).
