[Exim] Bounces in Reject Log

Hi

I have added these lies to my config to block Emails from this domain. The
errors, however don't go into the reject log. How can I get them to go
there instead of in the normal log? I suppose I really want exim to
generate an error 550 don't I when it comes across a rogue sender? How
would I do that?

forced_fail:
driver = aliasfile
senders = *@webfusion.co.uk
file = /usr/local/etc/exim/bouncelist
search_type = lsearch*

bouncelist looks like this
*:      :fail:  550 You are not authorised to send mail to this recipient
