[Exim] transport error using exim 3.34

Hello everyone,

     I am running exim 3.34 on my MX 10 machine and exim 3.33
on my MX 20 machine.

     I just noticed that the little fail_percent thingy I put in
the "configure" file a few months ago has been failing on exim 3.34
(it still works properly with exim 3.33). I've read the release notes
but don't see anything about this.

The configure file for both machines has this in the "directors"
section:

fail_percent:
  driver      = smartuser
  local_parts = ^.*%
  new_address = ":fail: We do not accept addresses containing percent signs"

and this in the "routers" section:

fail_percent:
  driver      = domainlist
  local_parts = ^.*%
  route_list  = "* localhost byname"
  self        = local

If I send mail to blah%blah@???, it says this in the exim 3.33
exim_main logfile:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2002-01-06 12:23:56 verify failed for SMTP recipient blah%blah@???
from <jimbotest@???> H=f158.pav2.hotmail.com (hotmail.com)
[64.4.37.158]
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

which is what I want to happen, but in the exim 3.34 exim_main logfile
it says this:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2002-01-06 12:17:39 16NInb-0001ls-00 <= jimbotest@???
H=f155.pav2.hotmail.com (hotmail.com) [64.4.37.155] P=esmtp S=918

for blah%blah@???

2002-01-06 12:17:39 16NInb-0001ls-00 == blah%blah@???
R=fail_percent defer (-1): error in router: transport missing
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++



Not sure what kind of "transport" it's expecting me to create.
I guessed and tried:


fail_percent:
driver = smtp

in the transport section, but that didn't work.

Can anyone shed some light? Thanks!
