Creating Your Own Online E-mail System in ASP.NET 2.0 - Using SendMail
(Page 4 of 4 )
It's by using the SendMail method of the Mail class that you finally send out your e-mail. It first sets up the IP address and port for the mail server, then sets the mode of sending e-mails and whether to use user credentials, then finally it invokes the Send (MailMessage mailMsg) function to send the email.
public int SendMail(MailMessage mail)
{
///Define the client to sent the e-mail
SmtpClient client = new SmtpClient();
///Set up the IP address of the mail server host
client.Host = ((WebMailProfile)HttpContext.Current.Application["WebMailProfile"]).MailServerIP;
///set up the port of the mail server
client.Port = ((WebMailProfile)HttpContext.Current.Application["WebMailProfile"]).MailServerPort;
///configure the properties for sending e-mails
client.DeliveryMethod = SmtpDeliveryMethod.Network;
//client.UseDefaultCredentials = false;
client.UseDefaultCredentials = true;
client.Credentials = new NetworkCredential("Xianzhong Zhu","abc123");
//client.EnableSsl = true;
///send e-mail
client.Send(mail);
return (0);
}
Author's Note: When you debug this sample, you should carefully populate the system profile info. From above, you can see that my mail server requires my mailbox to provide the user name and password and use the user credentials, but there is no need to provide an SSL link. This may be different from your mail server's request. So here I hard-code the user name and password ( 'abc123' is the password of my sample mailbox-sdmyzxz2007test@163.com), and when you run this sample, please give the proper information according to your mail server's request.
