Porting System.Web.Mail to System.Net.Mail

Question

The following function works fine:

    protected void SendWebMailMessage(string DisplayName, string From, string ReplyTo,
        string To, string Subject, string Body, string Attachments)
    {
        System.Web.Mail.MailMessage msg = new System.Web.Mail.MailMessage();
        msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver",
             "smtpout.secureserver.net");
        msg.Fields.Add(
             "http://schemas.microsoft.com/cdo/configuration/smtpserverport", 25);
        msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", 
             2);
        msg.Fields.Add(
             "http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", 1);
        msg.Fields.Add(
             "http://schemas.microsoft.com/cdo/configuration/sendusername", From);
        msg.Fields.Add(
             "http://schemas.microsoft.com/cdo/configuration/sendpassword",
             mailpassword);
        msg.To = To;
        msg.From = DisplayName + "<" + From + ">";
        msg.BodyFormat = MailFormat.Html;
        msg.Subject = Subject;
        msg.Body = Body;
        msg.Headers.Add("Reply-To", ReplyTo);
        SmtpMail.SmtpServer = "smtpout.secureserver.net";
        SmtpMail.Send(msg);
    }

However, I get a build warning saying that System.Web.Mail is deprecated and that I should use System.Net.Mail. So I used System.Net.Mail, and I came up with the following function to replace the old one:

    protected void SendNetMailMessage(string DisplayName, string From, string ReplyTo, 
        string To, string Subject, string Body, string Attachments)
    {
        MailAddress addrfrom = new MailAddress(From, DisplayName);
        MailAddress addrto = new MailAddress(To);
        MailAddress replytoaddr = new MailAddress(ReplyTo);
        System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
        msg.From = addrfrom;
        msg.To.Add(addrto);
        msg.ReplyTo = replytoaddr;
        msg.IsBodyHtml = true;
        SmtpClient smtp = new SmtpClient("smtpout.secureserver.net");
        smtp.Credentials = new NetworkCredential(From, mailpassword);
        smtp.Send(msg);
    }

I have no exceptions or errors, but my message never goes through. Can anyone tell me what I can do wrong? Thanks in advance.
