+====generic=====
+If you run a postfix host without a signed domain such as "localdomain.local" you can't send mails. Therefore you need a "generic mapping":
+Content file "/etc/postfix/generic":
+myaccount@myserver mymailadresse@domain.net
+Execute:
+  postmap /etc/postfix/generic
+====sasl_password====
+Content "/etc/postfix/sasl_password":
+  mail.domain.net myuser@domain.net:my-strong-secret
+Execute:
+  postmap hash:/etc/postfix/sasl_password
