Here you can find short name of local computer, as
defined in your network settings. There will be no domain
information because your computer can be known completely
different on external network, depending on your dial-up
settings, local network settings, etc..
Although you can write to this property - it will not
change your network settings. Changing this value will only
affect information visible to users that connect to your
server, if Pop3 server needs to provide such info to
users.
Usually, you might want to set this property to
something meaningful and use it in GreetingMessage
or GoodbyeMessage
properties.
