Taco, I honestly thought I'd covered the DNS issue in my post.  I agree
I wanted control of the DNS for further testing, and I've made
arrangements for that.  The DNS has been moved over to my servers, and
by tomorrow, when all the root-servers point to my nameserver, and I'm
using the same file for his domain that I use for hundreds of other,
working domains, we'll see if that fixes it.

The fact is that he's NOT using CNAMES and there IS an MX record.  I'm
not sure I like the MX records; I've NEVER seen "@" symbol used on the
right side of a DNS record.  However, there's nothing in RFC 1035 that
will disallow it.  I know that doesn't mean that BIND implements it the
way I read RFC 1035, which is why I'm hoping that you're right and my
hosting the DNS resolves the problem.

Here's a copy of his previous DNS (reformatted so it will look okay in
email clients using 80 column screens and non-proportional fonts); it
looks ok to me except for the aforementioned issue of the "@" on the
right side of the MX record.

$TTL 86400
@    IN       SOA     ns3.safepages.com. postmaster.safepages.com. (
                          1   ; Serial
                      10800   ; Refresh after 3 hours
                       3600   ; Retry after 1 hour
                     604800   ; Expire after 1 week
                      86400 ) ; Minimum TTL of 1 day

                IN      NS    ns3.safepages.com.
                IN      NS    ns4.safepages.com.
                IN      A     207.224.22.148
                IN      MX    10  @
localhost       IN      A     27.0.0.1
;
pop             IN            CNAME    @
smtp            IN            CNAME    @
www             IN            CNAME    @
ftp             IN            CNAME    @
 
While there ARE CNAME records, none of them should affect the mail
delivery; MX points to the domain and the domain is represented by an A
record.

Thanks for your suggestion, but I really don't think it's the issue. 
Unless the "@" implementation isn't as written in RFC 1035.
