Exactly - and my problem is knowing where it is getting this from.

Not sure where I can find the outgoing mail but I can give more info that might 
help.

It's a long story, but probably relevant, so -

We first set up a family LAN around 12 years ago, and called it xxx.net.  
Eventually I realised that xxx.net was actually a TLD name, so not a good 
idea.  Actually I now own both xxx.org and xxx.net, but I decided that with 
this install I'd correct what had long been our practice.

On the new CentOS install I set the server name to borg.xxx.lan.  I then 
changed every reference to xxx.net in /etc/hosts, and set about changing the 
Postfix config files.  (I know now that it is using postfix.sendmail,)  Somewhere 
I either have some other file still pointing to the old name, or, more likely, 
postfix is still using it somewhere.

I have been careful to re-map transports and restart postfix after any changes 
to the config files.  The following from maillog may shed some light as to where 
the problem lies:

The old transport read:

xxx.net	local:
.xxx.net	local:
*	smtp:[mailhost.zen.co.uk]
.*	smtp:[mailhost.zen.co.uk]

Those lines have been left and 

xxx.lan	local:
.xxx.lan	local:

added in.

A more likely suspect, I think, is main.cf - the relevant lines in the old one 
being 

mydestination = $myhostname, localhost.$mydomain, $mydomain, xxx.lan
myhostname = borg.xxx.net
mydomain = xxx.net
myorigin = $mydomain
masquerade_domains = $mydomain
#masquerade_domains = |borg.xxx.net
mynetworks = 192.168.0.0/24,127.0.0.0/8

and the latest version (after many thrashing edits)


mydestination = $myhostname, localhost.$mydomain, $mydomain, xxx.lan
myhostname = borg
mydomain = xxx.org
myorigin = $mydomain
# masquerade_domains = $mydomain
mynetworks = 192.168.0.0/24,127.0.0.0/8

Sorry this was so long, but it seemed important to give you as much info as I 
could.
