使用

 

public static void main(String[] args) throws AddressException, UnsupportedEncodingException, MessagingException {

		MailSenderInfo mail = new MailSenderInfo();
		
		//设置附件
		mail.setAttachFileNames(new String[]{
				"D:\\Desktop\\首页.jpg",
				"D:\\Desktop\\测试账户.java"
		});
		//设置抄送人
		mail.setCcAddress(new String[]{"[email protected]","[email protected]"});
		//设置正文
		mail.setContent("<h3>http://www.baidu.com</h3>");
		//设置发件邮箱
		mail.setFromAddress("[email protected]");
		//设置发件邮箱密码
		mail.setPassword("123456");
		//设置邮件服务器
		mail.setMailServerHost("mail.XX.com");
		mail.setMailServerPort("25");
		//设置邮件主题
		mail.setTitle("我是主题");
		//设置收件人
		mail.setToAddress(new String[]{"[email protected]"});
		//设置用户名
		mail.setUserName("33");
		mail.setValidate(true);
		MailSenderUtil.sendHtmlMailWithLocalAttach(mail);
	}

 

有些邮件服务器中，username需要写全称（即包含@及之后的数据，如[email protected]），否则会报错：

javax.mail.AuthenticationFailedException: 535 5.7.0 Error: authentication failed: authentication failure
