161013, Java implementation of bulk mail with attachments

To complete the Java Bulk Mail feature, you must first add the Mail.jar and Activation.jar packages

Here is an example of the message: import Java.io.file;import java.util.properties;import Java.util.vector;import javax.mail.internet.mimeutility;/*** Send Message Class * @author Shi Peng * @version 2016.10.19**/public class Mailsenderinfo {// The IP and port of the server sending the message is private string Mailserverhost;private string mailserverport = "25";//the address of the sender of the message is private string fromaddress ///Email recipient's address private string[] toaddress;//login Mail sending server username and password private string Username;private string password;// Whether you need authentication private Boolean validate = false;//message subject private string subject;//The text content of the message private string content;//The file name of the message attachment privat E String fileName = "";//attachment file collection private vector filename = new vector ();/*** get mail Session properties * @return */public Properties Getpropertie S () {Properties p = new Properties ();p. put ("Mail.smtp.host", This.mailserverhost);p.
