The log shows your application tries to send a message to the recipient from an external domain. For sending to external domains, SMTP servers require sender to authenticate himself for security reasons. You should enable SMTP authentication as follows (C# syntax):
 
 
Code: 
   
    
    
      
       Smtp mailer = new Smtp();
 
 // Enable logging
 mailer.Log.Enabled = true;
 mailer.Log.Filename = @"C:\log.txt";
 mailer.Log.Clear();
 
 // Create SMTP server object
 SmtpServer server = new SmtpServer("mail.domain.com");
 
 // Setting SMTP authentication data
 
 // Full email or just username "jdoe",
 // depends on SMTP server
 server.AccountName = "jdoe@domain.com"; 
 server.Password = "password";
 server.AuthMethods = AuthenticationMethods.Auto;
 
 // Add the SMTP server
 mailer.SmtpServers.Add(server);
 
 // Compose and send the message
 mailer.From.Email = "jdoe@domain.com";
 mailer.To.Add("marry@domain.com");
 mailer.Subject = "Test";
 mailer.BodyPlainText = "Test";
 mailer.Send(); |

 Best regards,
 Andrew
