The JavaMail API is a set of abstract APIs that model a mail system. The API provides a platform independent and protocol independent framework to build Java technology based email client applications. The JavaMail API provides facilities for reading and sending email. The package defines classes that are specific to mail systems based on internet standards such as MIME, SMTP, POP3, and IMAP.
