Problem with centos - postfix - all mail i queued

[xsas]

Hi

I recently has begun with Ispconfig and Centos, previosly I had worked always with Debian, but for long maintenance I would try Centos for his long time support.

Well, I followed the howto

http://www.howtoforge.com/perfect-se...er-ispconfig-3

and everything is ok.

But when I test the mail, I have found this:

MTA([127.0.0.1]:10025) during fwd-connect (Negative greeting: at (eval 86) line 596.): id=09025-08 (in reply to end of DATA command))

I have disabled selinux and reviewed all but I miss something.

Thanks in advanced
