Postfix sending AUTH=<> to SMTP Server

[David Rose]

I've got postfix setup to receive mail from a local script and it sets its from address to ***@domain.com when sending, I can see this is received by postfix and sent onto the exchange server for delivery fine. However I get a bounce back from the mail server to the originating address stating I need to be authenticated. I've got all the authentication configured correctly.

I did a tcpdump and I can see the base64 login works perfectly however Postfix is tagging the MAIL FROM with some extra parameters:

MAIL FROM:<***@domain.com> SIZE=24579 BODY=8BITMIME AUTH=<>

If I manually telnet to the exchange server and add this AUTH=<> to the mail from then it bounces, if I remove it, it works perfectly.

Is there anyway I can remove this AUTH parameter from the MAIL FROM?
