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.
as far as I know, amazon blocks email ports. For ftp, check the messages log and pure ftpd log file for errors. Maybe pure ftpd is not able to connect to the mysql database anymore.
Amazon apparently has unblocked the ports but no email in or out. pureftp is not logging anything at this time. I will probably need to rebuild the server. My other cloud server is running CentOS 7 with less issues but it is not an EC2 instance, ftp is also an issue on that server.
