postfix ignores auth at smtp server

[gaspedalo]

Hi, I have troubles relaying mails to a smtp server that need authentication. I've gone through several howtos without troubles but the verbose mode of mail.inof shows that postfix does not initiate the login and authentification process.

the relay relatet part of my main.cf:
#SMTP mit SASL Authentification verwenden
smtp_sasl_auth_enable = yes
#da stehn die passwoerter drin
smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth
#Zusatzoption, keine anonyme anmeldung
smtp_sasl_security_options = noanonymous
relayhost = mail.danielbauer.com

smtp_auth holds mail.danielbauer.com userasswd

Can you see any mistake?

thanks in advance,
daniel
