Java uses Commons-email to send and encapsulate messages

In this example, we use Commons-email to send messages and encapsulate them, support HTML content and attachments, and Commons email is a mail client component under Apache's Commons sub-project, which is based on javamail and greatly simplifies the sending and receiving of messages.

The tool class supports multiple senders, multiple cc people, multiple bcc, multiple attachments, and more. Very powerful.
