      You don't have to use A names you can keep to IP addresses. You can use the include argument as a kind of wildcard.

      You can use MXtoolbox to check if your SPF record is correct. Just remember that some older DNS servers do not use the SPF type so you will have to use a txt record along with a SPF

        @slazer2au This server does not send email directly. it is all relayed. I finally found it though..

        Based on your comment about the A record, i changed it to this:

        domain.com. IN TXT "v=spf1 ip4:XXX.XXX.239.40/29 include:_spf.google.com ~all"

          What do you mean? and SPF record is a TXT record.

            No, SPF and TXT are two different record types.

              I stand corrected.
              http://en.wikipedia.org/wiki/Sender_Policy_Framework

              They used to be implemented as TXT records. I was unaware that they officially had their own type now.

                That's why you have to do both. Some systems still don't honor the SPF record.

                  But SPF is being obsoleted.
                  http://en.wikipedia.org/wiki/List_of_DNS_record_types uses a source document here: http://tools.ietf.org/html/draft-ietf-spfbis-4408bis-21 and section 3 basically states the SPF was never implmented well.

                      Yea, I had a client that we host their public DNS records. it was a pain to add TXT and SPF records to all his files.

                        We do a lot of email consulting and have to deal with it all of the time.
