Now you don't need the account + password of the mailbox , now use the account + third-party authorization code (in the mailbox settings)
First of all, the sender needs to open the stmp and pop3 services in the qq mailbox (the first two anyway)
First come first: relatively simple
1 SmtpClient client = new SmtpClient( " smtp.qq.com " ); 2 client.EnableSsl = true ; 3 client.UseDefaultCredentials = false ; 4 client.Credentials = new System.Net.NetworkCredential( " Sender Email Address " , " Third-party authorization code " ); 5 MailAddress from = new MailAddress( " Sender's email address " , " Express from the second uncle ", Encoding.UTF8); // Initialize the sender 6 MailAddress to = new MailAddress( " Recipient's email address " , "" , Encoding.UTF8); // Initialize the recipient; the recipient is not divided into qq or 136 Mailbox 7 // Set the mail content 8 MailMessage message = new MailMessage( from , to); 9 message.Body = " Mail content " ; 10 message.BodyEncoding = System.Text.Encoding.UTF8; 11 message.Subject = " Title " ; 12 message.SubjectEncoding = System.Text.Encoding.UTF8; 13 message.IsBodyHtml = false; 14 15 //发送邮件 16 try 17 { 18 client.Send(message); 19 } 20 catch (InvalidOperationException iex) 21 { } 22 catch (Exception ex) 23 { }
Another one, you can add multiple recipients and cc's
Email email = new Email();
email.mailFrom = "Sender's Address";
email.mailSubject = "Mail Subject";
email.mailBody = "Email Body";
email.isbodyHtml = true; //Is it HTML
email.host = "smtp.qq.com";//If it is a QQ mailbox: smtp:qq.com, and so on
email.mailToArray = new string[] { "[email protected]", "[email protected]" };//Receiver mail collection
email.mailCcArray = new string[] { "[email protected]" };//Cc mail collection
if (email.Send())
{
Response.Write("<script type='text/javascript'>alert('Successful sending!');history.go(-1)</script>");//If the sending is successful, it will prompt to return to the current page;
}
else
{
Response.Write("<script type='text/javascript'>alert('发送失败！');history.go(-1)</script>");
}
