+It's very important to configure the file ''/etc/postfix/generic'' with a remapping of the local
+users to complete email addresses:
+<code>
+# REMEMBER!!!! After making changes to this file you must run:
+#
+# postmap /etc/postfix/generic
+#
+#
+username   username@complete.server.address.com
+</code>
+In that way, every outgoing email is rewrited from username@localhost to username@complete.server.address.com and nowadays email servers can recognize it as a valid email
+address.
+After that **don't forget to run postmap /etc/postfix/generic** in order to update the database with the fresh configuration.
