3.0.0.8 rc1 mail relay problem

[booten]

Im experience a bit problem having the server send mails through the relay host.

warning: SASL authentication failure: All-whitespace username.

my relayhost doesnt need username/password.
And i have those fields empty in ispconfig server setup for mail.

But it adds this in the sasl_password file:
smtp.myisp.net :

I have solved this temporary by disabling the sasl_password map file in postfix conf.

But is there a better way? to get ispconfig to not try to authenticate my relay with blank username/password on some way?
