localhost.localdomain is already there but still the undelivered mails after changing resolv.conf as descripted above.
What's in /etc/hosts, and what's the output of Code: ifconfig ? What's in /etc/postfix/main.cf (please strip out the comments)?

That's wrong. It must be Code: 127.0.0.1 [B][COLOR="Red"]localhost.localdomain[/COLOR][/B] localhost 10.0.1.1 server-1.de server01 ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts instead.
Please run Code: postconf -e 'mydestination = /etc/postfix/local-host-names' and add localhost.localdomain to /etc/postfix/local-host-names at the bottom (if it's not in there already). Then restart Postfix.
It seems to be ok now I've done what you had commended. Then I got an similar "loops back to myself" notice. It works whith "postconf -e 'mydestination = /etc/postfix/local-host-names'" but even it did'nt seems the best solution to point postfix to every virtualdomain. So I've tried a few setting in localhostnames and at least I only had to add "localhost.localdomain" to my destination. In /etc/postfix/local-host-names I add "localhost.localdomain" and another "loops back.." notice entry. Now, if I use dig, dig ist asking the local nameserver bind9 and if its does'nt know the anwser the local bind will ask one of the dns-resolvers. So the local nameserver bind9 will be able to anwser the most usual dns questions very fast be using its cache. Many thanks for your help, falko
