Hey, I have quite big, and strange problem I have 2 mailservers in my configuration. They're exactly the same, only difference is hostname. All related files in: /etc/courier /etc/postfix /etc/default are the same (of course hostname and server_id is different). Problem is: first server is working fine, second gives (when I'm trying to send anything): postfix/smtpd[3539]: warning: unknown[10.10.0.11]: SASL LOGIN auhentication failed: authentication failure. My system is Ubuntu 9.04. Regards, Michael
Problem SOLVED There was an error in /etc/pam.d/* files - wrong database login credentials. Kind regards, Michael
