[gentoo-user] Wrong domain in e-mail failure messages

[Peter Humphrey <peter@prh.myzen.co.uk>]

Hello list,

I've just received a delivery failure message from my ISP, zen.co.uk, saying 
it couldn't deliver an e-mail I'd sent. There's only one thing wrong (apart 
from the reason for the failure, which is out of my control). It's shown in 
the second line of the failure notice:

	Received: from [xx.xx.xx.xx] (helo=wstn.localnet)

I've bowdlerised the IP, and wstn is the name of this box, but where did it 
get localnet from? I've grepped /etc for it, and I've searched my home 
directory tree for it. Both searches turned up empty.

I use KMail, which is set up to send all outgoing mail directly to my ISP via 
SMTP; no other box is involved. And I hope my ADSL router isn't interfering.

My head's getting sore from being scratched. Has anyone a clue for me?
