We have two Spam filters, Barracuda and Spamhaus that are rejecting our company Emails to our customers. Mxtoolbox gave me SPF warnings and our ISP ,Godaddy said they didn't think our SPF record looked correct.

this is what we have in the SPF record now
v=spf1 include:mail.domainname.com ~all

What should it look like?

thanks.

this is the article explain it.

http://www.openspf.org/SPF_Record_Syntax

and I use to use the generator

http://www.spfwizard.net/

include will pass to the SPF record of the domain after it, however if that is the same domain who does it.

it will fail since it pass to it.

So does this sound like a reason why these spam filters are blocking their company Emails?

I have managed Mx and DNS records before and never needed an SPF record created at the Hosted name server.

ok at this part in the wizard
IP addresses in CIDR format that deliver or relay mail for this domain:

Do I enter the external IP address for the mail server or the internal network ip?

"v=spf1 mx a ip4:1XX.2XX.68.162/29 ?all"

Do I put the quotes in as well or leave them off?

v=spf1 mx a ip4:1xx.2xx.68.162/29 a:yourdomain.com -all

if you have multiple domain that send email off from this SMTP

v=spf1 mx a ip4:1xx.2xx.68.162/29 a:yourdomain.com;yourdomain1.com -all

just build it off from the generator, make your life much easier.
