Change the root 'from' address from hostname

[Guern]

Hello,

This is an easy one I guess, but I can't seem to find out how to do it.

My system currently sends messages from 'root@system'. This is an invalid email address, so I want to to send from 'root@mydomains.com'. How do I change this without changing the hostname of the machine? There does not seem to be a way of specifying the sender with the 'mail' command.

Thanks.

Should have stated I'm using sendmail / fedora

sendmail has the "-f" (or is it -F) value when sending from command line. Application-generated outgoing mail will still use the default construct based on hostname, that's what mail does.....

You need to either masquerade as the domain you wish to represent or use something like the genericstable feature.

Masquerading seems to be the easy solution.

Thanks.

You could also use:
mailx -r "xx@xxx.xxx" ....
