Sender address rejected: Domain not found - solution

"Sender address rejected: Domain not found"
There is a file called "/etc/postfix/generic" that creates a hash
table that Postfix uses to map outgoing email addresses.
smtp_generic_maps = hash:/etc/postfix/generic
- save and exit
- open /etc/postix/generic in vi and add the email address you want to
change and what you want to change it to.
- save and exit
postmap /etc/postfix/generic
- restart Postfix
