[vchkpw] The header info lost ? what is the progress between qmail-local and vdelivermail ?

[Jerry Chou]

I set up a perl script to snap the mail by forward from .qmail file:

# to_file.pl    grasp the output by directed from .qmail
#!/usr/bin/perl -w

use strict;

open (DEST, ">>/home/test_sms/testfile.dat")||die "$!";
while (<STDIN>) {
        print DEST $_;
}
print DEST  scalar(localtime),"The Line Is End Of Here.\n";
print DEST "*" x 80;
print DEST "\n\n\n";
close (DEST);
#end********************

and the .qmail-vpc is:

[root@mail test_sms]# less /home/vpopmail/domains/vpc.jeje/.qmail-vpc
| /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox
| /home/test_sms/to_file.pl

so, the one copy sent to owner's localbox and another one copy written to
/home/test_sms/to_file.pl

and here is a copy of an entry of this file:

but I go to see the copy of owner's, only diffrence is
there are two lines than above:

Return-Path: <[EMAIL PROTECTED]>
Delivered-To: [EMAIL PROTECTED]

but any mail I forward with .qmail and .qmail-EXT has no such lines
and I notice many mailling list soft only has reciept user's email address
in that tow lines in whole header.

as qmail-local trasfer this parameter to vdelivermail but can not
trasfer to a file by a pipe ?

how vdelivermail knows who is the real destination of mail if
it get a mail from mailling list?

Thanks
