          System.Net.Mail.MailAddress fromAddress = new System.Net.Mail.MailAddress(@ConfigurationSettings.AppSettings["EmailFrom"]);
          smtpClient.Host = @ConfigurationSettings.AppSettings["MailServerName"];

Solution 2

Sometimes certificate errors occur due to the invalid date time settings in the system clock. Make sure that it is the current date and time.
I dont see any problem in your code...

try this,

MailAddress mailfrom = new MailAddress ( "frommail@gmail.com" );
MailAddress mailto = new MailAddress ( "tomail@gmail.com" );
MailMessage newmsg = new MailMessage ( mailfrom, mailto );

newmsg.Subject = "Subject of Email";
newmsg.Body = "Body(message) of email";

////For File Attachment, more file can also be attached

Attachment att = new Attachment ( "G:\\code.txt" );
newmsg.Attachments.Add ( att );

SmtpClient smtps = new SmtpClient ( "smtp.gmail.com", 587 );
smtps.UseDefaultCredentials = false;
smtps.Credentials = new NetworkCredential ( "mail@gmail.com", "pwd" );
smtps.EnableSsl = true;
smtps.Send ( newmsg );
