Hello,

Does the domain have a SPF record and is it correct? You can verify the correct syntax by using SPF: Project Overview.

[inetbizo]

Of course both domains have proper SPF records. They are set to their dedicated IP4 address. They are on two seperate cpanel servers. The original email arrives for webmaster@domain.com server 2, matches the forward and copies to admin@domain-two.com on server one and is rejected for SPF. X-Loop came from SPF.ORG So i'm not sure why you're pointing me back to the same place. They state that SPF will break on forwards if it does NOT include X-Loop header.
