JavaMail验证器位于javax.mail包中,与同名的java.net类不同。这两者不共享同一个验证器,因为JavaMail API使用的是Java 1.1,而Java 1.1没有Java.net变体

请参阅:
1)请为POP3电子邮件使用适当的jar文件:
import java.util.Properties;
import javax.activation.*;
import javax.mail.*;
2) 然后构建您的消息:
Properties props = new Properties();
props.put("mail.smtp.host", <mail_server>);
props.put("mail.smtp.port", <port>);
props.put("mail.smtp.user", <user>);
props.put("mail.smtp.password", <pw>);
props.put("mail.smtp.auth", <logon>);
props.put("mail.from", <from>);
Session session = Session.getInstance(props, null);
try {
MimeMessage msg = new MimeMessage(session);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, <email_to>);
msg.setRecipients(Message.RecipientType.CC, <email_cc>);
msg.setRecipients(Message.RecipientType.BCC, <email_bcc>);
msg.setSubject(x_subject, Globals.q_UNICODE_MAIL);
msg.setSentDate(new Date());
msg.setHeader("Disposition-Notification-To", x_from);
//
//<build your Multipart message>
//
Properties=newproperties();
props.put(“mail.smtp.host”);
props.put(“mail.smtp.port”,);
props.put(“mail.smtp.user”,);
props.put(“mail.smtp.password”,);
put(“mail.smtp.auth”,);
道具放置(“mail.from”,);
Session Session=Session.getInstance(props,null);
试一试{
MimeMessage msg=新MimeMessage(会话);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,);
msg.setRecipients(Message.RecipientType.CC,);
msg.setRecipients(Message.RecipientType.BCC,);
msg.setSubject(x_subject,Globals.q_UNICODE_MAIL);
msg.setSentDate(新日期());
msg.setHeader(“处置通知到”,x_from);
//
//
//
3) 最后,连接并发送:
Transport transport = session.getTransport("smtp");
if ( <logon_required> ) {
transport.connect(<mail_server>, <user>, <pw>);
}
transport.sendMessage(msg, msg.getAllRecipients());
Transport-Transport=session.getTransport(“smtp”);
如果(){
交通。连接(,);
}
transport.sendMessage(msg,msg.getAllRecipients());
