        Dim Mail As MailMessage = Nothing
        Dim smtp As SmtpClient = Nothing
        Dim Expediteur As String = CompteGmailDeLExpediteur
        Dim Destinataire As String = AdresseMailDestinataire
        Try
 
            Mail = New System.Net.Mail.MailMessage
            Mail.SubjectEncoding = UTF8Encoding.UTF8
            Mail.BodyEncoding = UTF8Encoding.UTF8
            Mail.Subject = "Test Smtp GMail"
            Mail.Body = "Message de Test Smtp GMail " & Now()
            Mail.From = New MailAddress(Expediteur)
            Mail.To.Add(New MailAddress(Destinataire))
 
            smtp = New SmtpClient()
            smtp.Host = "smtp.gmail.com"
            smtp.Port = 25
            smtp.EnableSsl = True
            smtp.Credentials = New System.Net.NetworkCredential(CompteGmailDeLExpediteur, MotDePasse) ' mot de passe d'application généré par Google 
 
            Try
                smtp.Send(Mail)
            Catch ex As Exception
                MessageBox.Show(ex.Message)
            End Try
            Mail.Attachments.Clear()
            Mail.Attachments.Dispose()
            Mail.Dispose()
 
        Catch ex As ApplicationException
