The receiving server is doing address canonicalization, as required
by the RFCs. The fact that your server is not doing the address
canonicalization is a serious bug, and should be fixed.

The real solution is not to use CNAMEs at all in your DNS, but
instead to have the hostnames resolve directly into the appropriate
IP addresses, and to make sure that the reverse DNS for that IP
address includes all the appropriate hostnames.
