I have server 2008 managing DNS for over 100 external facing website. I need to ensure that the SPF records are setup correct as i am getting conflicting results from MX Toolbox.
Kitterman is coming back without errors (see attached)
XMToolbox is throwing the attached error
the info from MXToolbox is as follows:
Note: Using TXT records to contain SPF information was designed as a transitional mechanism as some servers and clients did not support the new SPF record type. It is best practice to publish your SPF record via DNS as both a SPF record and and TXT record. When you do this, they MUST match exactly in accordance with RFC 4408 section 3.1.1.
I have used the text file to create the SPF record, whats the difference
im running server 2008 r2 to manage the DNS
