Did my ISP set up our SPF records correctly?
|
|
Hello,
I asked our ISP to enter the following three lines into our DNS:
caea.com. IN TXT "v=spf1 ip4:216.138.203.130 -all"
caea.com. IN TXT "spf2.0/mfrom ip4:216.138.203.130 -all"
email-server.caea.com. IN TXT "v=spf1 a -all"
Below is what our ISP sent me. It is the raw information for our domain.
The last three lines were entered per my request. I notice that the
"caea.com" and the "email-server.caea.com" are not entered into the DNS.
Is the SPF record set up correctly in our DNS?

I also enabled the Sender ID, recipient filtering, and
connection filtering on our Exchange 2003 server. I thought I had taken
the necessary steps to reduce the amount of spam NDRs. However, today,
our inboxes have been inundated with spam NDRs. Is there anything else I
can do?
Thank you,
Millie Kwan
