Hello everyone, I try to deliver mail to a server running Exchange. I have Postfix version 2.4.5 under Ubuntu. My Postfix and the opposite Exchange want to use NTLM, but this fails:

In my /etc/postfix/main.cf I have: smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd smtp_sasl_security_options = Is it possible to use NTLM with Postfix? Or can I get it to use another logon protocol? Thank you in advance. Kay
