I am pulling my hair out trying to add an SPF reccord to my SBS 2003.
I am getting massive ammounts of spam email that has spoofed my email address.
I have SBS 2003 SP2 with a static public IP address. I use SMTP email that is sent directly to my IP address.
There is no SPF record for my domain name (using microsoft Sender ID Framework SPF Wizzard) but an IP address (I presume my ISPs) is listed in A records. mail servers listed in MX records list my domain and IP address.
In the DNS server on my SBS box there is no external listing for my domain - just the .local domain.
I have tried using creating an SPF record at openspf.org but what do I do with the txt that it created. Some are saying that it should go in the DNS on my server others say it has to go on the ISPs server.
