DynDNS: Lookup for [_spf.google.com] failed

[alsmith]

I'm seeing this message DynDNS: Lookup for [_spf.google.com] failed often in my lfd.log. I see the file /etc/csf/csf.dyndns has the entry _spf.google.com in it.
I've been searching here and on google to find what should be in this file. The header says only FQDN. I cannot ping this however I can get it when I do a nslookup.

Code: Select all

#nslookup -q=TXT _spf.google.com
Server:         8.8.8.8
Address:        8.8.8.8#53

Non-authoritative answer:
_spf.google.com text = "v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all"

What should I do about this?

found out my server company put this in.
I was also hoping it would help with a solution delivering email to comcast.net. I'm trying smtp.comcast.net, mx1.comcast.net, mx2.comcast.net to see if they might help.
