Exim doesn't (necessarily) know that it is a CNAME. All it knows is that
it gave one name to the DNS resolver, and it got back a different name
along with the IP address. This also occurs when, for example, a
single-component name is "widened" to a FQDN by the resolver.

'fraid not.
However, reading the code, I cannot see why it should be changing the
name to the new one in the example you give. I will have to set up a
test to try to figure out exactly what is happening.
