MimeMessageHelper

MimeMessageHelper is a class in the JavaMail API that provides helper methods to easily create and manipulate MimeMessage objects. It simplifies the process of creating email messages by providing methods to set the sender, recipients, subject, and content of the email.

Some of the common methods provided by MimeMessageHelper are:

1. setFrom(String email): Sets the sender of the email.

2. setTo(String email): Sets the primary recipient of the email.

3. setCc(String email): Sets the carbon copy recipient(s) of the email.

4. setBcc(String email): Sets the blind carbon copy recipient(s) of the email.

5. setSubject(String subject): Sets the subject of the email.

6. setText(String text, boolean html): Sets the content of the email. The second parameter specifies whether the content is in HTML format or plain text.

7. addAttachment(String filename, File file): Adds an attachment to the email.

By using MimeMessageHelper, developers can easily create and send email messages with attachments, set multiple recipients, and customize the content of the email
