Elmah - Catch an Error, but still log it and send email?

Question

First I found that you can catch it and log it inside a catch, but this doesn't send an email. Then I found out about using the Error Signal class. That worked, however what wasn't apparent from reading, is that it treats the error like normal, so when I signal the error it goes to the custom error page still, I don't want that to happen.

What I want to do is catch that error, log it, send the email, but stay on the page the error happened so I can provide special feedback. I do not want it go to the custom error page.

How can I accomplish this?

EDIT: This is what I have and it redirects me to the custom error page.

    Try
        smtpClient.Send(mailMessage)
    Catch smtpEx As SmtpException
        errorSignal.FromCurrentContext().Raise(smtpEx)
    Catch ex As Exception
        errorSignal.FromCurrentContext().Raise(ex)          
    End Try

Edit: Posting my web.config sections that involve Elmah (besides the connection string hah) And there is nothing in my Global.asax file involving Elmah.

  <configSections>
    <sectionGroup name="elmah">

The below should work (i do the exact same thing you are talking about)

try {
  // do something
} catch (Exception ex) {
  Elmah.ErrorSignal.FromCurrentContext().Raise(ex); // logs and sends the error through elmah
  // write a message to the user
}

and if you want a nice framework for displaying the message you can check out smokesignals (disclaimer: it's my work)
