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.
