No you can't read the contents of it. If you read it, you can be charge by the law.

Evesdropping, spying, hacking, man in the middle are the cases you may face if you read the email not intended for you

You can't read that. Its not the scope of IAG

IAG is used for filtering, bandwidth management, etc... It is not for looking at the contents of an email.

In terms of files, Sangfor IAM can only search up the extension name and file type. It looks for possible malware. It also has the ability to regulate HTTP, FTP upload and download activities depending on the real file type.

That is impossible because of the Data Privacy Act Law

That is not the feature of IAM.

SANGFOR IAG offers sophisticated content auditing for popular Instant Messaging applications (Yahoo Messenger, Skype, Line, and so on), Email, and Social Media.

That is in violation of the DATA PRIVACY ACT, which is a law.

Viewing any information, whether it be email content, passwords, or other sensitive data, is a breach in and of itself.
