rewrite rule when using forwardfile

Hi,

I sent a mail to exim-users a month ago about my difficulties with
rewrite rules not being applied when using a forwardfile director.

I didn't get any replies, so I've left it a while before trying again.
I'd also appreciate any suggestions of more details I could include or
how I could be clearer to increase my chances for assistance :-)

If I am doing wrong by posting again, my apologies. I considered
posting simply the url to my previous message, but I presume that
would be worse because then people would have to follow it.

My original post follows (althought this time I have appended a Z to
my address, so it is spread over the internet a little less...):

I'm using Exim version 3.34 #3 built 04-Jan-2002 11:25:07

I have a set of addresses in /etc/exim/mailinglists/us, and the
following in my directors configuration:

lists:
driver = forwardfile
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply
domains = haus
file = /etc/mailinglists/${local_part}
no_check_local_user
forbid_pipe
forbid_file
errors_to = nick-errors@nickpiper.co.ukZ

I also have a bunch of rewrite rules such as

*@*.haus $1@haus
nicholas@haus nick@nickpiper.co.ukZ Ffrs

so that any machine inside my LAN can easily send mail, with a from
address such as user@melon.haus, which is then rewritten to their
correct address. I don't want to rewrite To: addresses, because
user@haus is deliverable, and I'd rather mail not try leave the LAN
only to come back in.

This appears to work just fine. If I send myself a mail via a simple
"echo test | mail nicholas" the mail starts with:

Hmm. I would have expected "nick-errors@nickpiper.co.ukZ", assuming that
that is a valid address.

Try running

exim -d9 us
test
.

to run a delivery with debugging turned on. The copious output will be
written to stderr. It may give you a clue.

Sorry for the long mail, I thought it better to include all the
context again.

It is valid, in that mail to it would work... it would arrive here,
and then my rule
*@nickpiper.co.uk nicholas@haus Tbc
would make it into nicholas@haus and deliver it to me.

I don't see anything which tells me what is wrong. Maybe there is a
clue and I'm missing it though, so I've included the results below.
For comparison, I've done the same thing with an "ordinary" address,
nicholas@honeypot.netZ. That rewrites just fine (AFAICS).

Oops. I should have said, "try running 'exim -d9 us' *as an admin
user*". Sorry about that.

The debug level has been forced down to 1 for a non-admin user. This
doesn't show anything interesting, unfortunately. I'm afraid you'll have
to try again, as root or exim or another admin user (if you have any set
up).

Ah :-)

I ran it as root, and I get

Verifying nick-errors@nickpiper.co.ukZ
nick-errors@nickpiper.co.ukZ in *@*.haus? no (end of list)

/me slaps head

I've now changed my errors address to one which will reach me, but not
in the domain nickpiper.co.uk.

Thanks for your help!
