outgoing_mail_header_filters use local hostname and ip

Browse Source 
Modify outgoing_mail_header_filters and mail-postfix.sh
files to result in the primary hostname, and the public
ip of the server showing in the first mail header route
instead of unknown and 127.0.0.1.  This could help lower
the spam score of mail sent from your server to some
public mail services.
