Yes, there is such line.
What does
host localhost
[root@main tk]# host localhost localhost has address 127.0.0.1
say from the commandline? How about

Fine.

Is the DNS error actually coming from the next hop for the mail?

Sorry - my knowledge (as my english too) isn't so great. What do you mean? I send a mail from outside my network - poll it with fetchmail - use postfix, amavis, clamd, spamd until it (should) lay down in my lokal mailbox where I look at this mail with KMail.

No your English is fine, I was not so clear. Normally is Postfix is trying to do a DNS lookup on an incoming mail and it is not happy, instead of accepting the mail and bouncing it, as we see here, it will instead NOQUEUE it right there while still talking to the incoming MTA.
That it accepted it and then explicitly bounced it makes it sound like the problem is coming from downstream of Postfix itself in one of your other steps.
I would think about selinux getting in the way of these other apps, if selinux is enabled. Is there anything in /var/log/messages from audit/selinux?
Also maybe try to temporarily defeat the other steps so you only use Postfix and see if that makes a difference.

Oh no - the main proble is my poor knowledge about postfix
I would think about selinux getting in the way of these other apps, if selinux is enabled. Is there anything in /var/log/messages from audit/selinux?
These are the messages to selinux in my /var/log/messages:
Sep 1 08:06:20 main kernel: selinux_register_security: Registering secondary module capability
Sep 1 08:06:20 main kernel: SELinux: initialized (dev selinuxfs, type selinuxfs), uses genfs_contexts

This I have seen when a subprocess started by Postfix is dying. Perhaps one of your series of mail filtering apps is dying.

That it is a 450 means that it is not a fatal error and the mail should be tried again, not the immediate bounce you see.
Try finding and fixing the 127.0.0.1/8 problem, afterwards if it didn't help check with ps -Af that all your filtering programs are active.

This was it !!!
In my master.cf was

-o strict_rfc821_envelopes=yes -o smtpd_error_sleep_time=0 -o smtpd_soft_error_limit=1001
Changed to 127.0.0.0/8 and it works
Many thanks to all the quys tried me to help, really
