About JavaMail APIs

Email usage is by far the most trusted mode and convenient mode of communication that has stood the test of time. Emails are instantaneous, cheap, and easy to use. No wonder their popularity in almost all businesses today. Integration of emails as a default medium of communication in many web and mobile applications has enhanced email acceptance. Due to the massive volume of emails, companies and businesses require email APIs for better data organization.

An email API is a collection of commands and functions that build an interface from a particular coding language to send and receive emails. JavaMail API is an email API designed using Java programming language that offers a framework that is both protocol and platform-independent for developing message and mail applications. It helps in the composition, reading and sending of messages in electronic formats.

How JavaMail API works

When sending an email, the API helps setup the user-owned ID, password and the To and FROM addresses. A simple mail transfer protocol host is then set together with values for the properties. Once a session object has been created and message details formed, the transport object is used to send the message.

The APIs are also used to receive emails. In this process, a session object is created after setting POP3 server values. A store object for POP3 is then created and connected. A folder object is created and opened using the API for mail retrieval and printing. Once this is done, the folder is closed, and the object is stored.

The API layer is independent of protocols such as SMTP, POP3, IMAP and MIME, although they are also supported in the API.
