下面是一个用JavaMail发送附件的例子,你参考参考,看是不是你的代码有问题?
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;public class AttachExample {
public static void main (String args[])
throws Exception {
String host = args[0];
String from = args[1];
String to = args[2];
String fileAttachment = args[3]; // Get system properties
Properties props = System.getProperties(); // Setup mail server
props.put("mail.smtp.host", host); // Get session
Session session =
Session.getInstance(props, null); // Define message
MimeMessage message =
new MimeMessage(session);
message.setFrom(
new InternetAddress(from));
message.addRecipient(
Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject(
"Hello JavaMail Attachment"); // create the message part
MimeBodyPart messageBodyPart =
new MimeBodyPart(); //fill message
messageBodyPart.setText("Hi"); Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart); // Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source =
new FileDataSource(fileAttachment);
messageBodyPart.setDataHandler(
new DataHandler(source));
messageBodyPart.setFileName(fileAttachment);
multipart.addBodyPart(messageBodyPart); // Put parts in message
message.setContent(multipart); // Send the message
Transport.send( message );
}
}

这个smtp不需要认证,你试一下
public void SendEmail(String mailfrom, String subject, String msgbody, String filename) {
Properties props = System.getProperties();
String host = "smtp.263.net";
String mailto = "[email protected]";
props.put("mail.smtp.host", host);
Session session = Session.getDefaultInstance(props, null);
try {
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(mailfrom));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(mailto));
msg.setSubject(subject);
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(msgbody);
MimeBodyPart mbp2 = new MimeBodyPart();
FileDataSource fds = new FileDataSource(filename);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(fds.getName());
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
msg.setContent(mp);
msg.setSentDate(new Date());
Transport.send(msg);
}
catch (MessagingException mex){
mex.printStackTrace();
Exception ex = null;
if ((ex = mex.getNextException()) != null) {
ex.printStackTrace();
}
}
}

你换一个不需要认证的SMTP试试看,或者自己装一个
IMail之类的邮件服务器可以很方便的测试!
等我试一下你的程序先!
