Either your content filter is chrooted or "localhost." (with the final ".") does not resolve in your DNS Perhaps you forgot to enclose localhost in [] in your filter definition:

content_filter = smtp:[localhost]:10025

Hi,

this problem is already solved.

You are right, it was a MX problem, I add arqui300.com in my MX field and work like a glove
