这就是我想要的

我想开发一个反馈表。因此，我创建了一个示例活动，用于从一个邮件地址向另一个地址发送电子邮件。但我希望该邮件无需身份验证即可发送。或者如果不可能，则将电子邮件地址更改为另一个电子邮件地址。有我的代码。

这是我的 Mail.java 类

    public class Mail extends javax.mail.Authenticator {
private String _user;
private String _pass;

private String[] _to;
private String _from;

private String _port;
private String _sport;

private String _host;

private String _subject;
private String _body;

private boolean _auth;

private boolean _debuggable;

private Multipart _multipart;


public Mail() {
    _host = "smtp.gmail.com"; // default smtp server
    _port = "465"; // default smtp port
    _sport = "465"; // default socketfactory port

    _user = ""; // username
    _pass = ""; // password
    _from = ""; // email sent from
    _subject = ""; // email subject
    _body = ""; // email body

    _debuggable = false; // debug mode on or off - default off
    _auth = true; // smtp authentication - default on

    _multipart = new MimeMultipart();

    // There is something wrong with MailCap, javamail can not find a
    // handler for the multipart/mixed part, so this bit needs to be added.
    MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
    mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
    mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
    mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
    mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
    mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
    CommandMap.setDefaultCommandMap(mc);
}


public Mail(String user, String pass) {
    this();

    _user = user;
    _pass = pass;
}

 public void setTo(String[] toArr){
     _to = toArr;
 }

 public void setFrom(String from){
     _from = from;
 }
 public void setSubject(String subject){
     _subject = subject;
 }

public boolean send() throws Exception {
    Properties props = _setProperties();

    if (!_user.equals("") && !_pass.equals("") && _to.length > 0
            && !_from.equals("") && !_subject.equals("")
            && !_body.equals("")) {
        Session session = Session.getInstance(props, this);

        MimeMessage msg = new MimeMessage(session);

        msg.setFrom(new InternetAddress(_from));

        InternetAddress[] addressTo = new InternetAddress[_to.length];
        for (int i = 0; i < _to.length; i++) {
            addressTo[i] = new InternetAddress(_to[i]);
        }
        msg.setRecipients(MimeMessage.RecipientType.TO, addressTo);

        msg.setSubject(_subject);
        msg.setSentDate(new Date());

        // setup message body
        BodyPart messageBodyPart = new MimeBodyPart();
        messageBodyPart.setText(_body);
        _multipart.addBodyPart(messageBodyPart);

        // Put parts in message
        msg.setContent(_multipart);

        // send email
        Transport.send(msg);

        return true;
    } else {
        return false;
    }
}



@Override
public PasswordAuthentication getPasswordAuthentication() {
    return new PasswordAuthentication(_user, _pass);
}

private Properties _setProperties() {
    Properties props = new Properties();

    props.put("mail.smtp.host", _host);

    if (_debuggable) {
        props.put("mail.debug", "true");
    }

    if (_auth) {
        props.put("mail.smtp.auth", "true");
    }

    props.put("mail.smtp.port", _port);
    props.put("mail.smtp.socketFactory.port", _sport);
    props.put("mail.smtp.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");

    return props;
}

// the getters and setters
public String getBody() {
    return _body;
}

public void setBody(String _body) {
    this._body = _body;
} }

这是我的发送电子邮件课程

public class SendEmail extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Mail m = new Mail("<USER EMAIL>", "<PASSWORD>"); 
    String[] toArr = {"<EMAIL-1>", "<EMAIL-2>"}; 
    m.setTo(toArr); 
    m.setFrom("<EMAIL>"); 
    m.setSubject("This is aSubject."); 
    m.setBody("This is my Email body"); 
    try { 

      if(m.send()) { 
        Toast.makeText(this, "Email was sent successfully.",Toast.LENGTH_LONG).show(); 
      } else { 
        Toast.makeText(this, "Email was not sent.", Toast.LENGTH_LONG).show(); 
      } 
    } catch(Exception e) { 
      Log.e("MailApp", "Could not send email", e); 
    } 
}


       }

}

是否需要身份验证取决于您的邮件服务器。大多数邮件服务器都需要身份验证来防止垃圾邮件。

大多数 SMTP 服务器只接受来自它们自己的网络（例如公司网络）的未经授权的电子邮件消息。当您需要使用第 3 方 SMTP 服务器时，需要授权。
