This looks valid per RFC 5321.  Is it a bug in the Mailman software (or
the version of it) that we are using here on this list?  Did you have
any problems with any other lists?  From RFC5321, "If a CNAME record is
found [during an MX lookup], the resulting name is processed as if it
were the initial name."
