Warning message in dnsstuff.com for SPF
Posted on 2007-11-30
If I check my domain on dnsstuff.com, it says that I dont have an SPF Record:
Your domain does not have an SPF record. This means that spammers can easily send out E-mail that looks like it came from your domain, which can make your domain look bad (if the recipient thinks you really sent it), and can cost you money (when people complain to you, rather than the spammer). You may want to add an SPF record ASAP, as 01 Oct 2004 was the target date for domains to have SPF records in place (Hotmail, for example, started checking SPF records on 01 Oct 2004).
So I added the following record to the Forward Lookup Zones in DNS:
(same as parent folder) Text (TXT) v=spf1 ip4:<ip address comes here> -all
But the warning does not go away.
I would like to get rid of this warning for my very basic network: 1 DNS server, 1 Domain, Exchange 2003 and 3 other computers connected to the server.
I know it can go pretty granular. I just want the basic stuff for SPF&
What do I do wrong?
