You still have 'CNAME' from here<br>
Do not use 'cname' for any of your DNS....<br>

Also I see the priority is '0' is that valid?<br>
Maybe change and see if it helps.<br>

0 is a perfectly valid MX pref. (16bit unsigned int per RFCs) - one
might argue if its smart to use it but it's valid. But I fully I
second your statement regarding CNAMEs, the record for www is quite
sure the culprit here.<br>
