email returned - user not found

[Stephen Torri <s torri lancaster ac uk>]

I am trying to email certain logs to my active email account. I have the
entry for mailing within logrotate.conf as:

/var/log/kernel {
	weekly
	mail s torri lancaster ac uk
	mailfirst
	create 0600 root root
	rotate 4
}

The error message is:

... while talking to zooty.lancs.ac.uk.:
>>> RCPT TO:<s torri lancaster ac uk>
<<< 550 cannot route to sender address <root internet torri linux>
550 s torri lancaster ac uk    User unknown

Now my domain torri.linux is not registered because its an internal LAN
sitting behind a masquerading firewall. So if the email server at
lancaster.ac.uk is trying to confirm that the sender domain actually
exists (spam filter) than its definitely going to fail.

Is there a way to fix this so that my logs use a proper sender email
address?
