發送電子郵件使用共享的電子郵件到Gmail

Question

Email email = new SimpleEmail(); 
String authuser = "......@gmail.com"; 
String authpwd = "*******"; 
// Very Important, Don't use email.setAuthentication() 
email.setSmtpPort(465); 
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd)); 
email.setDebug(true); // true if you want to debug 
email.setHostName("smtp.gmail.com"); 

email.getMailSession().getProperties().put("mail.smtp.auth", "true"); 
email.getMailSession().getProperties().put("mail.debug", "true"); 
email.getMailSession().getProperties().put("mail.smtp.port", "465"); 
email.getMailSession().getProperties().put("mail.smtp.socketFactory.port", "465"); 
email.getMailSession().getProperties().put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
email.getMailSession().getProperties().put("mail.smtp.socketFactory.fallback", "false"); 
email.getMailSession().getProperties().put("mail.smtp.starttls.enable", "true"); 
email.setFrom("........@gmail.com", "SenderName"); 
email.setSubject("TestMail"); 
email.setMsg("This is a test mail?"); 
email.addTo(".............@gmail.com", "ToName"); 
email.send(); 

和它提供了以下異常

SEVERE: org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.gmail.com:465 

Answer 1

但這對我來說

Email email = new SimpleEmail(); 
String authuser = "...@gmail.com"; 
String authpwd = "xxxx"; 
email.setSmtpPort(587); 
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd)); 
email.setDebug(true); 
email.setHostName("smtp.gmail.com"); 
email.getMailSession().getProperties().put("mail.smtps.auth", "true"); 
email.getMailSession().getProperties().put("mail.debug", "true"); 
email.getMailSession().getProperties().put("mail.smtps.port", "587"); 
email.getMailSession().getProperties().put("mail.smtps.socketFactory.port", "587"); 
email.getMailSession().getProperties().put("mail.smtps.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
email.getMailSession().getProperties().put("mail.smtps.socketFactory.fallback", "false"); 
email.getMailSession().getProperties().put("mail.smtp.starttls.enable", "true"); 
email.setFrom("........@gmail.com", "SenderName"); 
email.setSubject("TestMail"); 
email.setMsg("This is a test mail?"); 
email.addTo("xxxx@gmail.com", "ToName"); 
email.setTLS(true); 
email.send(); 

Answer 2

工作不要你需要tell Commons Email that you're sending a TLS email：

email.setTLS(true); 

在您致電email.send（）之前？

我不確定這是否會解決您的問題，因爲我不確定您是否遇到連接到smtp.gmail.com:465的問題或者成功發送給它（錯誤消息/異常就像你提出的那樣是模棱兩可的），但是據我所知，這絕對是缺少的東西。

Commons Email用戶指南提供了一個使用SSL的Gmail示例。

https://commons.apache.org/proper/commons-email/userguide.html

SSL/TLS（端口465） - > email.setSSLOnConnect（真）;

Email email = new SimpleEmail(); 
email.setHostName("smtp.gmail.com"); 
email.setSmtpPort(465); 
email.setAuthenticator(new DefaultAuthenticator("username", "password")); 
email.setSSLOnConnect(true); 
email.setFrom("user@gmail.com"); 
email.setSubject("TestMail"); 
email.setMsg("This is a test mail ... :-)"); 
email.addTo("foo@bar.com"); 
email.send(); 

STARTTLS（端口587） - > email.setStartTLSEnabled（真）;

Email email = new SimpleEmail(); 
email.setHostName("smtp.gmail.com"); 
email.setSmtpPort(587); 
email.setAuthenticator(new DefaultAuthenticator("username", "password")); 
email.setStartTLSEnabled(true); 
email.setFrom("user@gmail.com"); 
email.setSubject("TestMail"); 
email.setMsg("This is a test mail ... :-)"); 
email.addTo("foo@bar.com"); 
email.send();
