title: Do CNAME records also forward MX requests?
body: <p>My DNS has a set up for the domain base.com that consists of A and MX records. There are several other domains that are set up with CNAME records, pointing to base.com. 
  Do I need to set up anything special (like extra MX records) for the CNAME domains, or will the CNAME records also forward any MX requests.</p>
  
  <p><strong>Example:</strong><br>
  Will an email sent to info@otherdomain.com be delivered correctly to the MX of base.com if these (and only these) DNS records are in place:</p>
  
  <pre><code>; A and MX set up for base.com
  base.com.  3600  IN  A  123.45.67.89
  mail.base.com.  3600  A  123.45.67.89
  base.com.  3600  IN  MX  10  mail.base.com.
  ; CNAME set up for otherdomain.com
  otherdomain.com. CNAME  IN  A  base.com.
  </code></pre>
