I installed postfix freshly as satellite system. I need to authenticate on my mail providers smpt. There postfix needs to build a sasl database from my sasl-passwd file. But it fails to do just that. How do I fix this error (last line)?:

root@confus:/etc/postfix# echo 'smtp_sasl_auth_enable = yes' >> main.cf

root@confus:/etc/postfix# echo 'smtp_sasl_security_options = noplaintext noanonymous' >> main.cf

root@confus:/etc/postfix# echo 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd' >> main.cf

root@confus:/etc/postfix# ll

total 116
