Sending Email Using SMTP Bluehost Server

Question

I use ASP.NET WEB API and I want to send an email from my application from an email created by https://www.bluehost.com/

Here is the configuration in the web.config file:

<system.net>
    <mailSettings>
        <smtp deliveryMethod="Network" from="[email protected]">
            <network host="mail.domain.com"
             port="465"
             userName="[email protected]"
             password="*****"
             enableSsl="true"   />
        </smtp>
    </mailSettings>
</system.net>

Here is my code:

SmtpClient smtpClient = new SmtpClient();
smtpClient.Timeout = 120000;
MailMessage mail = new MailMessage("[email protected]", "[email protected]"); 
mail.Body = "Here is the body of my email";
mail.IsBodyHtml = true;
smtpClient.Send(mail);

I am receiving the following error:

Network Error (tcp_error)
A communication error occurred: "Operation timed out" The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

Note that I have tried configuring SMTP directly in the above code, but still it didn't work.
I had tested from host smtp.gmail.com and it worked fine, so I guess the issue is from the new host.
Any help is much appreciated.

Answer 1

Please try this below code segment.

SmtpClient smtpClient = new SmtpClient();
smtpClient.Port = 465; // can check port for ssl - 587 and non ssl - 25
smtpClient.Host = "mail.domain.com";
smtpClient.EnableSsl = true;
smtpClient.Timeout = 10000;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new System.Net.NetworkCredential("[email protected]","password");

MailMessage mail = new MailMessage("[email protected]", "[email protected]", "test", "test");
mail.BodyEncoding = UTF8Encoding.UTF8;
mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

smtpClient.Send(mail);

Answer 2

For SMTP, I used port 26 and mail.company.com. My host server is bluehost.
