"blocked using zen.spamhaus.org'"

Your IP is blacklisted.  Check with spamhaus to see if it's your, or you subnet.  Contact your host to see if you can get a clean ip.

probado en otro servidor otro ip, despues de instalar AntiSpam

Activar SpamHause

La misma cosa rechaza todos los correos. menos gmail.
Is from DNS ?
