There is a check:
sendmail -bv user@domain.tld
then root gets an email where it's written where the mail would be send. Then you know if postfix deals this domains locally or not.

After this you can look deeper the the configuration. If it's local, you have to find out if it's a DNS problem or postfix problem.
