Thanks again. The problem was the wildcard MX record for ***our***
domain. It seems quite a few people got caught in that situation
initially.

So in brief for the all new DNS managers:

Most of the managers have decided that the wildcards were more trouble
than they were worth and removed it.

The only place a wildcard MX record should be used is for off-internet
hosts. For all the hosts in your domain, they should be known by
you, the DNS maanger, and MXed accordingly.

For folks in Canada, it is likely that *.NRC.CA MX record
might be the table if you got it from Ca registrary.
