Getting rt_mailgate to work with exim

Greetings.

I’m not having any success getting rt-mailgate to work with exim.

I tried following the instructions at
http://www.exim.org/pipermail/exim-users/Week-of-Mon-19991018/014792.html
to no avail.

added the following to /etc/exim.conf:

MACROS

RTPATH = /opt/rt/bin
RTQUEUE = eritmo

deliver to the rt scripts

rt_pipe:
driver = pipe
path = “/usr/local/bin”
command = “perl -T /opt/rt/bin/rtmux.pl
rt-mailgate eritmo
${substr_1:${local_part_suffix}}”
log_output
user = rt
group = rt

rt:
driver = smartuser
transport = rt_pipe
domains = “rt.MDOM”
local_parts = “^rt(-.*)?”
suffix_optional
require_files = “+RTPATH/rtmux.pl”

and removed the ineffectual

rt: “| /opt/rt/bin/rt-mailgate eritmo correspond”

from /etc/aliases. when attempting to send mail to the rt address,
nothing happens. Has anyone else faced these problems and overcome them?
