Problems with System.Net.Mail

Hi,

I have written some very simple code that runs within my website that
use system.web.mail to send an email using the SMTP server here. It
works fine. However when I alter the code to work using system.net.mail
instead and put the code in a VB.NET class library it no longer works.
It does not raise an exception though. The mail just does not get sent.

Does anyone have an idea as to why this might be? Hers the code that
does not work:

                Dim oMsg As MailMessage = New MailMessage
                Dim oAdd As MailAddress
                Dim SmtpMail As SmtpClient = New
SmtpClient(SMTP_SERVER)

                'Create email notification
                oMsg.From = New MailAddress(ATLS_EMAIL)
                oAdd = New MailAddress(***@me.com")
                oMsg.To.Add(oAdd)
                oMsg.Subject = "whatever"

                'TODO - put name in here of location manager
                oMsg.Body = "stuf...."

                SmtpMail.Send(oMsg)

Heres the code that does work:

            Dim oMsg As MailMessage = New MailMessage()
            oMsg.From = AppSettings("ATLS_EMAIL")
            oMsg.To = "m*@me.com"
            oMsg.Subject = "whatever"
            oMsg.BodyFormat = MailFormat.Html
            SmtpMail.SmtpServer = AppSettings("SMTP_SERVER")
            SmtpMail.Send(oMsg)

There's code differences between sending mail with
system.web.mail and sending mail with system.net.mail.

For complete examples using system.net.mail, see :
