postfix problem

[Karl Auer]

I'm trying to send email from scripts. I have mailx and postfix
installed. Sending email works, but not quite properly.

Specifically, the mail arrives showing a sender of "
kauer at kt1.biplane.com.au", where "kt1" is the name of the laptop and
"kt1.biplane.com.au" is the hostname (and the value in /etc/hostname).

I have tried putting various things in /etc/mailname and changing the
value of myorigin in /etc/postfix/main.cf, to no avail. As far as I can
tell, postfix always uses the value in /etc/hostname. If /etc/hostname
doesn't have a domain (i.e., is just "kt1", it will append the correct
domain to it, but I can't seem to get rid of that pesky hostname!

Is there a way to tell postfix to just send all from "biplane.com.au"?

I found this:

http://www.postfix.org/ADDRESS_REWRITING_README.html#generic


But that looks like I'd need a set of generics for every sending
account. I just want one global override on outbound emails.

Regards, K.
