Relaying e-mail to the outside of NAT

  • Need to masquerade the local origin name to make it looking as a qualified domain name:


  • Add to /etc/postfix/main.cf: 
    
# Rewrite the From address in Postfix V2.2:
smtp_generic_maps = hash:/etc/postfix/canonical

  • In file /etc/postfix/canonical, we specify the address re-writing: 
    
@node18.linux.class    @capone.rutgers.edu
@unisys18.linux.class  @capone.rutgers.edu

  • Run command 
    
postmap /etc/postfix/canonical
