The MX record points from an email domain to a FQDN. The FQDN must have an A or AAAA record (and not a CNAME) which in turn resolves to an IP address. See http://tools.ietf.org/html/rfc5321#section-5.1
Talking of my case, MX records *do* point to FQDN, which in turn have valid A records (no CNAMEs). All I had to do was to prevent Exim from utilizing A record of the recipient's domain if MX records resolution failed.
