Rewiting may not be mandatory, but it is certainly true that a domain
needs to have either an A record or an MX record to recieve email
according to the spec. Your has neither, and given the presence of
a CNAME then rewriting the address to use that CNAME doesnt seem like
an unreasonable thing to do.

You should add an MX record to that domain - but mixing MX and CNAME
is a fairly bad idea too (and that should be easily found in google).
