I have had my vm moved to an Amazon EC2 instance. Centos 6.9, lastest ISPConfig 3. Websites are working but the email and ftp are not communicating with the outside world. I can ssh into the vm with no problem and configured sftp so that i could upload files. What should I look at to get the email at least to work? My clients are now wanting emails on their domains. example FTP connect log: Status: Connecting to ??.??.??.??:21... Status: Connection established, waiting for welcome message... Status: Initializing TLS... Status: Verifying certificate... Status: TLS connection established. Command: USER ftp1_??? Response: 331 User ftp1_??? OK. Password required Command: PASS ************ Response: 530 Login authentication failed Error: Critical error: Could not connect to server this was working before the move.
