transport error generated frozen message, how to avoid?

I'm using a pipe driver to cyrdeliver, my delivery looks like

cyrus:
driver = pipe
command = /usr/sbin/cyrdeliver -r $return_path -m $
{substr_1:$local_part_suffix} -- $local_part
user = cyrus
group = mail
return_output
log_output
message_prefix =
message_suffix =

Now when exim receives an email for a valid domain, it doesn't know
whether cyrus can deliver the email. In the eximlog I get the
following output:

1HCGcn-0008KE-L2 <kpaf@markus.fischer.name>: cyrus transport output:
kpaf: Mailbox does not exist

This is fine, however it causes the message to freeze and generates an
email to the postmaster.

I would like to *not* freeze these kind of failed deliveries, exim
should just trash it and should *not* generate an email to postmaster
about this.

How can I tell exim so?

thanks,
- Markus

Why don't you use an LMTP transport?
<http://www.google.de/search?&q=exim+lmtp+cyrus> should reveal all
information you need.
