some emails not being forwarded

some emails not being forwarded

Hi,

Just recently setup a Zoho account and changed the MX records for my domain.  Quite happy with this service.

However for some email addresses (info, ssladmin, hostmaster), the test emails I am sending do not seem to be forwarded to the forwarding address.  My primary ones are working but I'm at a loss regarding how to figure out what is happening to the other emails - ssladmin/hostmaster are very important for simple domain ownership validation that some ssl providers use.

Can someone help?

Many thanks,
Paul
