I have the following code written in a class file which is suppose to fire a mail from the ftp site (which it was firing earlier) but now it has stopped so kindly suggest some solution. Code is as under:

*****************************************************************

using System.Reflection;
using ASPEMAILLib;

/// <summary>
/// Summary description for CompMail
/// </summary>

public class CompMail
{
    public CompMail()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    public void fireMail(int comp_seqid)
    {
        MailMessage mailMsg = new MailMessage();
        mailMsg.To = "tanind@gmail.com";
        mailMsg.From = "Manage-a-company.com";
        mailMsg.Subject = "Hi! Test Mail";
        mailMsg.Body = "Hello this is a test mail" + comp_seqid.ToString();
        mailMsg.BodyFormat = MailFormat.Text;

        SmtpMail.SmtpServer = "localhost";
        SmtpMail.Send(mailMsg);
    }
}

Please help me out of this problem. I have also added ASPEMAILLib.dll and its reference in the file. Still not working.

Thanks in advance,
