Postfix & SASL Authmethod

[Alex Huth]

Hi guys!

I've setup up Postfix & SASL on a 4.9 System. It does SMTP-Auth for delivering 
to the ISP Mailserver. It is working fine so far. Tehre is only one warning 
when connecting to the remote SMTP-Server:

<ISP-IP> offered AUTH option multiple times

How can i define which Option to use when my SMTP is connecting? The 
security_option in the main.cf is "anonymous"
Is there a solution to handle this?

Thanks
