Hi Pravesh, 

The specified string is not in the form required for an e-mail address

The problematic code was as follows:

MailMessage objMsg = new MailMessage(regEmail.Text.ToString(), "me@mysite.com");

I fixed the issue by replacing that code with this:

MailMessage objMsg = new MailMessage();

objMsg.From = new MailAddress(regEmail.Text.ToString());

objMsg.To.Add(new MailAddress("me@mysite.com"));

It is also helpful to use a regular expression validator in your user control to make sure the address is valid, you can use the following code for asp:

<asp:RegularExpressionValidator ID="regex1" ControlToValidate="regEmail" ErrorMessage="Please enter a valid email address" ValidationExpression="^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$" ValidationGroup="regGroup" runat="server" Display="None" SetFocusOnError="True"></asp:RegularExpressionValidator>

Or if you'd prefer to validate the email in C#

public static bool IsValidEmail(String Email)
{
    if( Email != null && Email != "" )
        return Regex.IsMatch(Email, @"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
);
    else
        return false;
}
