NAME
       mailname - the visible mail name of the system


DESCRIPTION
       The file /etc/mailname is a plain ASCII configuration file, which on a Debian system contains the visible
       mail name of the system.  It is used by many different programs, usually programs that wish  to  send  or
       relay mail, and need to know the name of the system.

       The  file  contains  only one line describing the fully qualified domain name that the program wishing to
       get the mail name should use (that is, everything after the @).
