Not rubbish at all - I'm afraid it's just not quite that simple.

Here's what we were using - masked for privacy:

abc.com RELAY
abc.com.au RELAY
abc.net RELAY
xyz.com.au RELAY

person1@xxxxxxxxxx   RELAY
person2@xxxxxxxxxx   RELAY
abuse@xxxxxxxxxx    RELAY
postmaster@xxxxxxxxxx     RELAY
sales@xxxxxxxxxx     RELAY
info@xxxxxxxxxx     RELAY
person3@xxxxxxxxxx       RELAY

To:aaa.com.au          "550 User unknown"

This resulted in everything for aaa.com.au being bounced "We do not relay".

I'm going to try a few different solutions after hours - naturally I 
want to limit the disturbance of testing during working hours.

Nigel.
