Try
{
Properties Props = new properties ();
Authenticator auth = new Email_autherticator ();
Props.put ("Mail.smtp.host", host);
Props.put ("Mail.smtp.auth", "true");
Session session = Session.getdefaultinstance (Props,auth);
MimeMessage message = new MimeMessage (session);
Set the message body
String htmltext= "< h1>helloMessage.setcontent (HTMLText, "text/html");//text/plain set the format of the message because it has an HTML document, the text/html format
Message.setsubject (Mail_subject);
Message.settext (mail_body); When using message.setcontent (), it seems impossible to use Message.settext ()
Message.setheader (Mail_head_name,mail_head_value);
Message.setsentdate (New Date ());
Address = new InternetAddress (Mail_from, "sunxiaoming");
Message.setfrom (address);
Address toaddress = new internetaddress (mail_to);
Message.addrecipient (message.recipienttype.to,toaddress);
Transport.send (message);
System.out.println ("Send ok!");
}
