使用JavaMail API在Android中发送电子邮件

我已经提到了以前对类似问题的回答，但它举例说明了使用Gmail的传出服务器配置。不过，我想使用JavaMail API的Web邮件，我公司使用的是：使用JavaMail API在Android中发送电子邮件

发送服务器：smtp.softcellindia.com

端口：

的加密类型：none

我试过使用下面的代码。但它似乎没有发送邮件。

import javax.activation.DataHandler; 
import javax.activation.DataSource; 
import javax.mail.Message; 
import javax.mail.PasswordAuthentication; 
import javax.mail.Session; 
import javax.mail.Transport; 
import javax.mail.internet.InternetAddress; 
import javax.mail.internet.MimeMessage; 
import java.io.ByteArrayInputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 
import java.security.Security; 
import java.util.Properties; 

public class MailSender extends javax.mail.Authenticator { 
    private String mailhost = "smtp.softcellindia.com"; 
    private String user; 
    private String password; 
    private Session session; 

    static { 
     Security.addProvider(new com.provider.JSSEProvider()); 
    } 

    public MailSender(String user, String password) { 
     this.user = user; 
     this.password = password; 

     Properties props = new Properties(); 
     props.setProperty("mail.transport.protocol", "smtp"); 
     props.setProperty("mail.host", mailhost); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.port", "25"); 
     props.put("mail.smtp.socketFactory.port", "25"); 
     props.put("mail.smtp.socketFactory.class", 
       "javax.net.ssl.SSLSocketFactory"); 
     props.put("mail.smtp.socketFactory.fallback", "false"); 
     props.setProperty("mail.smtp.quitwait", "false"); 

     session = Session.getDefaultInstance(props, this); 

     } 

    protected PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication(user, password); 
    } 

    public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception { 
     try{ 
     MimeMessage message = new MimeMessage(session); 
     DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain")); 
     message.setSender(new InternetAddress(sender)); 
     message.setSubject(subject); 
     message.setDataHandler(handler); 
     if (recipients.indexOf(',') > 0) 
      message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients)); 
     else 
      message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients)); 
     Transport.send(message); 
     }catch(Exception e){ 

     } 
    } 

    public class ByteArrayDataSource implements DataSource { 
     private byte[] data; 
     private String type; 

     public ByteArrayDataSource(byte[] data, String type) { 
      super(); 
      this.data = data; 
      this.type = type; 
     } 

     public ByteArrayDataSource(byte[] data) { 
      super(); 
      this.data = data; 
     } 

     public void setType(String type) { 
      this.type = type; 
     } 

     public String getContentType() { 
      if (type == null) 
       return "application/octet-stream"; 
      else 
       return type; 
     } 

     public InputStream getInputStream() throws IOException { 
      return new ByteArrayInputStream(data); 
     } 

     public String getName() { 
      return "ByteArrayDataSource"; 
     } 

     public OutputStream getOutputStream() throws IOException { 
      throw new IOException("Not Supported"); 
     } 
    } 
}

我想你应该检查你的服务器的SMTP端口。 – 2012-02-27 07:31:47

我终于通过改变 props.setProperty（“** mail.host **”，mailhost）; 至 props.setProperty（“** mail.smtp.host **”，mailhost）; 并删除以下行 props.put（“mail.smtp.socketFactory.port”，“25”）; props.put（“mail.smtp.socketFactory.class”， “javax.net.ssl.SSLSocketFactory”）; props.put（“mail.smtp.socketFactory.fallback”，“false”）; props.setProperty（“mail.smtp.quitwait”，“false”）; – 2012-03-01 08:36:33

@Harshul ::你可以在这里添加你自己的答案。我试图使用相同的概念，但注意到异常：554消息被拒绝。 – Harpreet 2012-04-09 11:54:22

我终于得到它的工作通过改变

props.setProperty("mail.host", mailhost);

到

props.setProperty("mail.smtp.host", mailhost);

和d选择以下行

props.put("mail.smtp.socketFactory.port", "25"); 
props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactor"); 
props.put("mail.smtp.socketFactory.fallback", "false"); 
props.setProperty("mail.smtp.quitwait", "false");

变化javax.net.ssl.SSLSocketFactory到javax.net.SocketFactory

是否适合你？ – 2012-05-07 13:46:53

发送服务器：smtp.yeah.net 端口：25 加密类型：无。可以成功发送邮件。 – fabs5068 2012-05-08 01:30:32
