Hello,
Are you seeing MX Host not error found errors in your log files?
Make sure that your configured DNS resolvers are reachable.
Also, postfix may be configured to require /var/spool/postfix/etc/resolv.conf
If that file does not exist you can copy your /etc/resolv.conf to /var/spool/postfix/etc/resolv.conf
