Here's a more detailed introduction:

 public void Sendmailusezj () {System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage (); Msg.        To.add ("[email protected]"); Msg.                To.add ("Fill in the address here such as [email protected]"); Msg.        To.add ("[email protected]"); Can be sent to multiple people//msg. Cc.        Add ("[email protected]"); Can be copied to many people msg. from = new MailAddress ("[email protected]", "SFADSXCVXXV", System.Text.Encoding.UTF8);/* The above 3 parameters are the sender address (can be written casually), Sender name, encoding */MSG. Subject = "AAAAA";//message header MSG. subjectencoding = system.text.encoding.utf8;//message header encoded MSG. Body = "adsssssssss";//message content Msg. bodyencoding = system.text.encoding.utf8;//message content encoded MSG. Isbodyhtml whether =true;//is an HTML mail//msg.        Priority = mailpriority.high;//message SmtpClient client = new SmtpClient (); Client. Credentials = new System.Net.NetworkCredential ("[email protected]", "77777777"); e-mail account password sent. This must be written about yourself, I use the 126 client. Host = "SMTP."126.com ";        Object userState = msg; try {//client.            SendAsync (msg, userState); Client.            Send (msg); Label1.Text = "sent successfully!!"        "; } catch (System.Net.Mail.SmtpException ex) {Label1.Text = "send failed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"; /Front desk label, needless to say}}

Incidental points:

The server address is: QQ mailbox
pop3:pop.qq.com;
Smtp:smtp.qq.com 163 Email

Pop3:pop.163.com
Smtp:smtp.163.com

The address of the Sina Free mailbox (SMTP) server is: smtp.sina.com

Sina free email inbox (POP3) the address of the server is: pop.sina.com

Other on the Internet to find it.
