Hi,
use this one might be helps you.


protected void SendEMail(string MailTo, string MailFrom, string MailSubject, string MailBody,string CC, string BCC,string Host,string Password,int PortNo)
{
MailMessage objEmail = new MailMessage();

objEmail.From = new MailAddress(MailFrom);

string[] MailItem = MailTo.Split(';');
for (int i = 0; i < MailItem.Length; i++)
{
objEmail.To.Add(new MailAddress(MailItem[i]));
}

objEmail.Subject = MailSubject;
objEmail.Body = MailBody;
objEmail.IsBodyHtml = true;
objEmail.Sender = new MailAddress(MailFrom);
objEmail.Priority = MailPriority.High;

try
{
SmtpClient client = new SmtpClient();
client.Host = Host;
ICredentialsByHost crd = new NetworkCredential(MailFrom, Password);
client.Credentials = crd;
client.EnableSsl = true;
client.Port = PortNo;
client.Send(objEmail);
}
catch (Exception exc)
{
}
}

Calling Pattern :

SendEMail("ToEMAIL", "FromMAIL", "Subject Line", "Mail Content", "CC ID", "BCC ID","smtp.gmail.com", "Password",587);

Simply use config file: http://hazaa.com.au/blog/how-to-store-smtp-mail-settings-in-the-appconfig-or-webconfig-file/[^], or provide your own configuration mechanism and set the necessary SmtpClient properties by code.
