Unity 3 - Sending Email with C#

Question

I have been looking all over the interwebs for a solution to this problem. I am trying to send an email through Unity and this is the code I currently have:

private void SendEmaill() { // Create a System.Net.Mail.MailMessage object MailMessage message = new MailMessage();

     // Add a recipient
     message.To.Add("curtisgmurray@gmail.com");

     // Add a message subject
     message.Subject = "Email message from Curtis sent by Unity";

     // Add a message body
     message.Body = "Test email";

     // Create a System.Net.Mail.MailAddress object and set the sender email address and display name.
     message.From = new MailAddress("curtisgmurray@gmail.com", "Curtis in Unity");

     // Create a System.Net.Mail.SmtpClient object and set the SMTP host and port number
     SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);


     //smtp.SendAsync(message, "Testing, from Curtis");


     // Create a System.Net.NetworkCredential object and set the username and password required by your SMTP account
     smtp.Credentials = new System.Net.NetworkCredential("curtisgmurray@gmail.com", "JuicyFruit");

     //Enable Secure Socket Layer (SSL) for connection encryption
     smtp.EnableSsl = true;

     // Do not send the DefaultCredentials with requests
     smtp.UseDefaultCredentials = false;        

     // Send the message
     smtp.Send(message); 
 }

The error that Unity 3 is throwing is:

Cannot implicitly convert type System.Net.NetworkCredential' toSystem.Net.ICredentialsByHost'. An explicit conversion exists (are you missing a cast?)

I tried sending an email without using authentication to avoid using this line but gmail requires one to provide authentication. Looking around the web, no one appears to have this issue.

Anyone know what is going on with this bug?

Thanks!

Note: JuicyFruit is not the actual password to my email, I changed it for posting purposes but in my actual code, I have the correct password inputted in.

Hello to all,

Thank you for everyone who has ever visited this question and replied to it. Many of your suggestions were very helpful, and my mind had slipped to close this question.

For those of you who still come here in the future looking for an answer, here was my solution code (Be mindful that the email address needs to be a gmail account):

 MailMessage mail = new MailMessage();
 
 mail.From = new MailAddress("[INSERT EMAIL HERE]");
 mail.To.Add("[INSERT EMAIL HERE]");
 mail.Subject = "[INSERT SUBJECT HERE]";
 
 string body = "[INSERT BODY HERE]";
 
 mail.Body = body;
 
 SmtpClient smtpServer = new SmtpClient("smtp.gmail.com");
 smtpServer.Port = 587;
 smtpServer.Credentials = new System.Net.NetworkCredential("[INSERT EMAIL HERE]", "[INSERT PASSWORD HERE]") as ICredentialsByHost;
 smtpServer.EnableSsl = true;
 ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
 try
 {
     smtpServer.Send(mail);
 }
 catch
 { 
     [INSERT FAILED SEND CODE HERE]
 }

Once again, thank you to all of you who posted answers :)
