[Gllug] Postfix

Hi All

I have setup a Postfix mail server and initially my domain was going to be
onetwosnap.com, but it has now changed to 12snap-mcd.com, now I have changed
this in postfix, but when I send a mail on the server to say root, it still
says that it comes from xyberpix at onetwosnap.com, and now
xyberpix at 12snap-mcd.com, where the hell would I change this?
Below is my main.cf file:

 when a Postfix daemon program is run with the -D option.
#
# Use "command .. & sleep 5" so that the debugger can attach before
# the process marches on. If you use an X-based debugger, be sure to
# set up your XAUTHORITY environment variable before starting Postfix.
#
debugger_command =
         PATH=/usr/bin:/usr/X11R6/bin
         xxgdb $daemon_directory/$process_name $process_id & sleep 5
