I coded for mailing in the form but now presently its not working, so i asked with my colleague about it, he replied : we cant mail before deployment it wont work. so I want to confirm it ,is it right?

I tried with this below code

public void sendMail()
        {
            try
            {
                MailMessage objeto_mail = new MailMessage();
                SmtpClient client = new SmtpClient();
                client.Port = 25;
                client.Host = "smtp.removed.in";
                client.Timeout = 10000;
 client.EnableSsl = true;
                client.DeliveryMethod = SmtpDeliveryMethod.Network;
                client.UseDefaultCredentials = false;
                client.Credentials = new System.Net.NetworkCredential("mdawood@XXREMOVEDXX", "XXREMOVEDXX");
                objeto_mail.From = new MailAddress("xxx@removed.in");
                objeto_mail.To.Add(new MailAddress(txtEmailId.Text));
                objeto_mail.Subject = "Password Recover";
                objeto_mail.Body = "Message";
                client.Send(objeto_mail);
            }
            catch (Exception ex)
            {
                Response.Write(ex.ToString());
            }

This is the code that worked without any issues on our project:

C#

        //////////////////////////////////////////////////////////////////////////
        /// <summary>
        /// Sends mail
        /// </summary>
        /// <param name="recipients"></param>
        /// <param name="subject"></param>
        /// <param name="message"></param>
        /// <param name="attachments"></param>
        internal override void Send(string[] recipients, string subject, string message, string[] attachments)
        {
#pragma warning disable 612,618
            var mail = new MailMessage();
#pragma warning restore 612,618

            mail.Fields[SmtpServer] = _smtpHost;
            mail.Fields[SmtpServerPort] = _smtpPort;
            mail.Fields[SendUsing] = 2;
            mail.Fields[SmtpUseSsl] = true;
            mail.Fields[SmtpAuthenticate] = 1; // 0=anonymous, 1=basic, 2=NTLM
            mail.Fields[SendUsername] = _username;
            mail.Fields[SendPassword] = _password;

            // set unicode encoding - it is also used for encoding email headers (not only the body)
            mail.BodyEncoding = Encoding.UTF8;
            // set email properties
            mail.From = string.Format("{0} <{1}>", _displayName, _username);
            mail.To = string.Join(";", recipients);
            mail.Subject = subject;
            mail.Body = message;
            //mail.Priority = MailPriority.Low;
            //mail.BodyFormat = MailFormat.Html;
            if (attachments != null)
            {
                foreach (var attachment in attachments)
                {
#pragma warning disable 612,618
                    //TODO: replace with System.Net.Mail.Attachment if supported
                    mail.Attachments.Add(new MailAttachment(Path.GetFullPath(attachment), MailEncoding.Base64));
#pragma warning restore 612,618
                }
            }
#pragma warning disable 612,618
            SmtpMail.Send(mail);
#pragma warning restore 612,618
        }
