Hi , dovecot doesnt log anything to /var/log/secure. its a default centos 4.4 installation. All dovecot messages are logged to /var/log/messages. I tried connecting to the port 110 via telnet directly and typed user <random name> and pass <random pass> if the username exist it shows authentication failure in the log and report user=root for eg if i try as root. but if i try some username like idontexist in the logs user= shows blank. but in both the cases it didnt log the remote host IP address the rhost= remains blank. How to make dovecot to log all connection attempts remote host ip address. Regards, Mohan.
