A Java API to send and receive emails. Jakarta Mail (previously JavaMail) is part of Jakarta EE (previously Java EE), but can also be used in Java SE via a separate download.

Jakarta Mail (previously JavaMail) is a Java API used to send and receive email via SMTP, POP3 and IMAP. Jakarta Mail is built into the Jakarta EE platform, but also provides an optional package for use in Java SE.

The current version and last release in the 1.x line is 1.6.5, released on March 10, 2020. Another open source JavaMail implementation exists - GNU JavaMail - while supporting only version 1.3 of the JavaMail specification, it provides the only free NNTP backend, which makes it possible to use this technology to read and send news group articles.

In 2018 JavaMail became part of the EE4J initiative under the Eclipse Foundation, and was renamed to Jakarta Mail.
