    Hello from Oklahoma!

    I have been researching SPF and Sender ID for my SBS2003 DNS and I am
    confused. In my DNS, the only forward lookup zones are for my internal
    network (red.local). There are no zone records for my external network name
    ( Where to I place my TXT entries for SPF and Sender ID? Do I
    request my ISP to put in the records at that level? Thanks for all your help!

  2. SPF records need to be published on your *public* DNS servers for the domain (which right now are Network Solutions). So, you need to
    go there (they probably have a web interface where you can manage DNS) and
    add that TXT record.

    I know you didn't ask this... but it is extremely important that you know
    how exactly are you sending mail (i.e DNS vs. Smarthost, static or dynamic
    IP, same IP as your A/MX record, etc.) before you publish those records. Bad
    records are probably worse than no records at all. Let us know if you need
    any help.

    Thanks, Javier, for your reply. I believed that was where it had to be, but
    all the examples I saw always referred to SBS. And thanks for the reminder
    about making sure how the messages are being sent. I'll ask more questions
    after I finish reading all the documentation.

    Unfortunately, it does not appear that Network Solutions allows TXT entries
    using their web interface, just MX, A, and CNAMES. I'll do more investigation.
    Best Regards,

  4. I'll ask more questions
    You can move your DNS to another provider (i.e. and keep
    the registration on Network Solutions. Or better yet, change registrar to a
    cheaper one that offers free DNS hosting and has TXT record capability (I
    like, but probably has also TXT available).

    Thanks for the recommendations. If I don't receive a satisfactory reply from
    Network Solutions, this may be the reason to change.
    Best Regards,
