Irrigation, enclosed I use the JavaMail SMTP class

SMTP usage Examples:
/*
* New SendMail () Send text message using GBK's default encoding
* New SendMail (encoding, text or HTML);
*/
Wuyu.javamail.sendmail mail = new Wuyu.javamail.sendmail ("GBK", true);
/*
* Mail.connect (SMTP server);
* Main.connect (SMTP server, username, password); SMTP-authenticated sender server
*/
Mail.connect (Args[0], args[1], args[2]);
for (int i = 0; i < Integer.parseint (args[3]); i++) {
System.out.print (i + "t");
/*
* Main.send (FROM,TO,CC,BCC, subject, body, attachment file name)
* TO,CC,BCC can fill in multiple mail addresses
* The attachment file name is NULL, indicating that the attachment is not sent
*/
Mail.send ("mmwy@ynwst.com", Args[4], "", "", "This is the subject" + I, "<b> This is the body </b>", null);
System.out.println (i);
}
Mail.close ();
