/PERSONAL_NAME=name
/NOPERSONAL_NAME
Specifies a personal name to be used when answering a message.
A personal name is a field of text that is appended to the end
of the From: field of mail messages you send. You can fill this
field with your full name or any other information.
The /PERSONAL NAME qualifier overrides the default personal name
specified with the SET PERSONAL_NAME command for this message
only. The /NOPERSONAL_NAME qualifier sends a message with a null
personal name field.
