<blush>

That is what comes of typeing rather than cutting & pasteing. The line should have read
foo		IN	A	1.2.3.4
		IN	MX 10	foo
</blush>

The real names are:

test		IN	A	80.68.91.63
		IN	MX 10	test

Because of DNS timeouts/propagation you may need to use the master name server: mint.phcomp.co.uk
What you seem to suggest is that a CNAME is an alias in all ways and not just for IP address,
so I can't have a separate MX record.
