I would find use another DNS provider where you can create an SPF record. That's about as easy as falling off a log, assuming you have easy control over your domain name's DNS address setting. Can't believe that NS would be so far behind the times.
dnsmadeeasy.com is one such DNS provider. I've also used namecheap.com as both registrar and DNS provider with good results.

Per their policy they will not change the Reverse DNS of our static IP to be anything other than mortonrb-pool5-static-4.ispxxx.com. I have control of my DNS records and can set that as an MX but I'm kind of worried about some spam filters having issues with such a long DNS name with the word "pool" in it when trying to send mail. Using their mail server as a smart host is out of the question because if they go down our ASA box will automatically fail over to our secondary ISP and be unable to connect to their down mail server. Do you think using this long DNS name will cause issues trying to send outbound email. BTW my DNS is hosted with network solutions and they don't support TXT records so I can't create an SPF.
