Check 1: wallace.net.nz MX record

Check 2: mail.wallace.net.nz A record

         Points to


Check 3: PTR record

         Points to mail.wallace.net.nz.
         Points to www.rangers.wallace.net.nz.
         Points to mail.ceremony.co.nz.

Better than some, but not perfect.

RFC specifies that there can be only one PTR record
for each in-addr.arpa address.  You have three.

Check 4: wallace.net.nz A record

         Does not exist.

Correct according to RFC, but some mailers will 
try delivering direct to the mail host before
looking up an MX record.  This, apparently, is
your problem.

Check 5: Sample SMTP session (verbatim:)

$ telnet mail.wallace.net.nz 25
