[Pkg-exim4-users] exim4 in etch - save all mails

I'm having a little trouble getting exim to do what I want, and I'm hoping
someone here could tell me what I'm missing...
Previously in exim3, I could configure an "unseen save" in the system
filter to save all mails passing the server. An extra X-Envelope-to:
header was added to the saved mail, so one could see both the
envelope-from and the envelope-to (i.e., up to 100 addresses) of all
Now, with exim4, the X-Envelope-to: headers appears to be abolished (see
Exim4.upgrade). When setting 'envelope_to_add' in the systemfilter file
transport, it nicely adds 'Envelope-to: system-filter' which of course
doesn't help me.
The only place where I have access to the $recipients variable containing
all recipients, is INSIDE the system-filter file. So something like
headers_add = "X-Envelope-to: $recipients"
in the systemfilter_file transport results in a panic.
On the other hand, adding an extra header in the system-filter file before
doing the unseen save does give me an x-envelope-to header in the saved
mail, but this header also appears on all copies delivered to end-users or
That's highly unwanted...
So, I tried the next setup in the system filter file:
headers add "X-Envelope-to: $recipients"
unseen save "/tmp/allmail"
headers remove "X-Envelope-to"
But now the X-Envelope-to headers don't even appear in /tmp/allmail.
It seems that they are being removed before the "unseen save" is started.
So, even though exim4 really is a lot more clean than exim3, I can't save
all mail including envelope to. For outbound mail with Bcc addresses, I
really need a record of those addresses in something like an envelope-to
Oh, and something else I tried: create a new router (also unseen) to just
send every mail through a copy-transport. This also doesn't do what I
want: every recipient address is passed though this router individually,
so messages are saved one time for each recipient. The first_time
condition can help reducing the number of times a message is saved, BUT
then only the first recipient is recorded.
Also tried fiddling around with batch_max stuff. At this customer's site
outbound mail is being held and pushed out every 5 minutes as long as the
DSL line is up. Otherwise it is pushed out every 30 minutes over fallback
ISDN. Problem here: addresses for held domains are not even routed until
actual delivery is attempted. So still multiple copies if a locally
originated message has both local and remote recipients.
I'm at a dead end here. Could someone help me out? Many thanks in advance!
