ah, the server you're using to send emails requires you to use SSL via STARTTLS, wich is the gmail smtp server.
with opensmtp i didn't tryed to use starttls, i don't if it supports at all.
check the docs if it supports

  Thanks for the reply. I changed my asp.net code to use opensmtp instead of System.Net.Mail but now its giving another error 


  "Smtp error occured: ERROR - Expecting: 250. Recieved: 530 5.7.0 Must issue a STARTTLS command first 24sm3331267ugf"


  Following is the code that I have used:


  OpenSmtp.Mail.MailMessage msg = new OpenSmtp.Mail.MailMessage();


              msg.AddRecipient("testuser at gmail.com",OpenSmtp.Mail.AddressType.To);

              msg.From = new OpenSmtp.Mail.EmailAddress("testuser at gmail.com");

              msg.Subject = "Test mail using .net2.0";

              msg.Body = "This is my msg Body";


              string MailServer  = "smtp.gmail.com"; 

              string MailUser   = "xxxxxx at gmail.com"; 

              string MailPass   = "xxxxx";

              int MailPort =  587;  


              OpenSmtp.Mail.SmtpConfig.SmtpPort = 587;

              OpenSmtp.Mail.SmtpConfig.SmtpHost = "smtp.gmail.com";

              OpenSmtp.Mail.Smtp oSmtp = new OpenSmtp.Mail.Smtp ("smtp.gmail.com",587);//MailServer, MailUser, MailPass, MailPort);

               oSmtp.Username="xxxxx at gmail.com";





  Please let me know where I am going wrong.

    I am using System.Net.Mail for sending mails in asp.net applications and it is working fine on windows xp m/c. But when I publish this on suse linux server with mono 2.0 and postfix smtp service installed and configured it gives an error either "Unable to validate data" or "Service not available".


    I have also read about sharpwebmail application on net for sending mails through ASP.Net on linux. Please suggest what should be best to use to run asp.net applications for sending mails on linux server.
