Sender address rejected: Domain not found - solution

[tonyw...@telusplanet.net]

The maillog was showing errors which contained this:

"Sender address rejected: Domain not found"

This is because the sender email being used was:
us...@localhost.localdomain

There is a file called "/etc/postfix/generic" that creates a hash
table that Postfix uses to map outgoing email addresses.

To get Postfix to masquerade email address do this:

- open /etc/postfix/main.cf in vi and enter this line of code:
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.

e.g:
us...@localhost.localdomain us...@example.com

- save and exit

- run this command to generate the hash file:
postmap /etc/postfix/generic

- restart Postfix
