Send email from yahoo, gmail or your smtp server through asp.net

To send a email from asp.net you need to follow these steps...

We use System.Net.Mail namespace to send email. Without going into details, lets have a simple working code to send emails through asp.net via two most popular smtp mail servers.

Gmail:

try
     {
        MailMessage mail = new MailMessage();     //using System.Net.Mail namespace
        mail.To.Add("xyz@yahoo.com");             //Enter reciever's email address
        mail.From = new MailAddress("abc@gmail.com");  //Enter sender's email address
        mail.Subject = "Testing mail...";
        mail.Body = @"Lets-code ! Lets-code to make it simpler";
        mail.IsBodyHtml = true;                  //Body of mail supports html tags
        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.Credentials = new System.Net.NetworkCredential("abc@gmail.com", "pwd");
        // Your gmail username and password    
        smtp.EnableSsl = true;            //Gmail uses a encrypted connection
        smtp.Send(mail);
        Response.Write("Mail Sent Successfully");
    }

catch(Exception ex)
    {   
        Response.Write(ex.Message);
    }

Yahoo:

Yahoo's Smtp host name is smtp.mail.yahoo.com. It uses port 25 and an unsecure connection. So, considering these, here's a code for yahoo.

 try 
     {    
         MailMessage mail = new MailMessage();
         mail.To.Add("xyz@gmail.com");
         mail.From = new MailAddress("abc@yahoo.com");
         mail.Subject = "This is subject of your mail";
         string Body = @"Its the body of your mail";
         mail.Body = Body;
         mail.IsBodyHtml = true;
         SmtpClient smtp = new SmtpClient();
         smtp.Host = "smtp.mail.yahoo.com";
         smtp.Port = 25;
         smtp.Credentials = new System.Net.NetworkCredential("abc@yahoo.com","pwd");
         // Your yahoo username and Password
         smtp.EnableSsl = false;         // SSL is disabled
         smtp.Send(mail);
         Response.Write("Mail Sent Successfully");
     }

catch (Exception ex)
     {      
         Response.Write(ex.Message);
     }

Yahoo appends its advertisements in your mail. So its better to use gmail.

Here's a list of other smtp mail servers:

• Hotmail Outgoing Mail Server (SMTP) - smtp.live.com (SSL enabled, port 25)

• Yahoo Plus Outgoing Mail Server (SMTP) - plus.smtp.mail.yahoo.com (SSL enabled, port 465, use authentication)

• MSN Outgoing Mail Server - smtp.email.msn.com (uses authentication)

• Netscape Internet Service Outgoing Mail Server - smtp.isp.netscape.com (port 25, uses a secure SSL connection)

If you want to mail from your own smtp mail server, just change the respective host,port.Check if your mail server supports SSL connection and enable/disable it accordingly.
