Elmah - Catch An Error But Still Log It And Send Email?

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.

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.
