All examples below are using the following frameworks/libs:

  • Hamcrest - Library of matchers, which can be combined in to create flexible expressions of intent in tests.
  • cactoos - Object-Oriented Java primitives, as an alternative to Google Guava and Apache Commons.
  • cactoos-matchers - Object-Oriented Hamcrest matchers

Inbox

JavaxMailInbox

Fetch the emails from the server using javax.mail framework:

public static void main(final String[] args) {
    final Properties smtp = new Properties();
    smtp.setProperty("mail.smtp.host", host);
    smtp.setProperty("mail.smtp.port", port);
    smtp.setProperty("username", user);
    smtp.setProperty("password", password);
    ...
    final Inbox inbox = new JavaxMailInbox(smtp);
    final Iterable<Msg> msgs = inbox.read(
        new Query("pop3s", "INBOX", new All())
    );
    for(final Msg msg : msgs) {
        System.out.println(msg);
    }
}

See Gmail SMTP connection properties as an example of a configuration for reading procedure.

Outbox

JavaxMailOutbox

Send an email to the target recipients using javax.mail framework:

public static void main(final String[] args) {
    final Properties smtp = new Properties();
    smtp.setProperty("mail.smtp.host", host);
    smtp.setProperty("mail.smtp.port", port);
    smtp.setProperty("username", user);
    smtp.setProperty("password", password);
    ...
    final Outbox outbox = new JavaxMailOutbox(smtp);
    outbox.send(
        new MsgOf(
            "from@server.com", 
            "to@server.com", 
            "Testing subj",
