email of TLD Pt stay on queue

I have installed a CMS (spip) in wich I have a newsletter (php + mysql). Emails as gmail.com, hotmail.com, etc register and receive emails. Contrary to TLD Pt that don't receive (for example sapo.pt, clix.pt, aeiou.pt). I have one VPS (apache 1.3.34) and going ro the servers queue the email is there and can't be delivered.Here is the message that appears:
"Message 1GQiGa-0001ZI-KA is not frozen
