I am trying to configure SPF records for our domains. I started out trying
to use the Microsoft Sender ID Framework SPF Record wizard at
http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/.
However after pulling out my hair with ambiguous error messages I ended up
using the SPF setup wizard at http://www.openspf.org/.
Using the wizard I was able to generate the following SPF record:
v=spf1 ip4:216.42.131.0/25 ip4:157.238.141.0/25 ip4:198.87.208.0/24
ip4:198.87.209.0/24 ip4:207.67.38.0/25 a mx a:smtp.frontiernet.net
a:smtp-server.rochester.rr.com a:www.netpot.com a:smtp.charter.net
a:smtp.shoreham.net a:smtpauth.earthlink.net a:smtp.sbcglobal.yahoo.com
a:smtp.east.cox.net a:mail.montanadsl.net -all
This is all well and good, but when I went to create a TXT record on our
Windows 2000 DNS server the record was truncated down to:
v=spf1 ip4:216.42.131.0/25 ip4:157.238.141.0/25 ip4:198.87.208.0
I tried adding line breaks to the record as follows:
v=spf1
ip4:216.42.131.0/25
ip4:157.238.141.0/25
ip4:198.87.208.0/24
ip4:198.87.209.0/24
ip4:207.67.38.0/25

a:smtp.shoreham.net
a:smtpauth.earthlink.net
a:smtp.sbcglobal.yahoo.com
a:smtp.east.cox.net
a:mail.montanadsl.net
-all
However we're seeing inconsistent SPF results from various MTA's. (Some
servers classify our messages as SPF_PASS and others as SPF_FAIL) Is anyone
here familiar enough with SPF to know if adding line breaks is valid syntax?
Thanks
