[Exim] Address "rewriting"

Hallo,

I changed the recipients in a -H file, i.e. the file now looks as follows:

16tOPi-0004La-00-H
mail 8 8
<>
1017992738 0
-ident mail
-received_protocol local
-body_linecount 114
-frozen 1017992739
-localerror
XX
1
newaddr@???

150P Received: from mail by server2 with local (Exim 3.33 #1 (Debian))
        id 16tOPi-0004La-00
            for <newaddr@???>; Fri, 05 Apr 2002 09:45:38 +0200
        043  X-Failed-Recipients: xxx@???
        055* From: Mail Delivery System <xxx@???>
        053F From: Mail Delivery System <xxx@???>
        027T To: newaddr@???
        059  Subject: Mail delivery failed: returning message to sender
        040I Message-Id: <E16tOPi-0004La-00@server2>
        038  Date: Fri, 05 Apr 2002 09:45:38 +0200

I replaced the original recipient address by the new address
"newaddr@???". When I now do a

exim -Mt 16tOPi-0004La-00

I get a "Spool format error for 16tOPi-0004La-00". How can I force exim to
send in each case? Or what is malformed in that header file (may be there's
a checksum)?

Thank you
Marco
