Alias file

[Mario Rafael]

        Hi :), I have several questions.... I have an /var/spool/mail/alias file
that is getting bigger and bigger each moment, what it's is purpose?, I
have taken a lookt at it and it seems that the messages double bouncing are
stored there... how can I directly throw those messages to /dev/null?,
thanks in advance.
