Documentation

SSL/TLS with sufficient verification should be enabled when sending emails. Explicitly disabling SSL/TLS results in email contents being exposed. Disabling verification of the recipient can lead to spoofing attacks.

Before
Email email = new SimpleEmail();
email.setSSLOnConnect(false);
email.setSSLCheckServerIdentity(false);
After
Email email = new SimpleEmail();
email.setSSLOnConnect(true);
email.setSSLCheckServerIdentity(true);
