Ang-st,

Here is a safer way to obtain the header values you need. If it works from the command line, e.g.,  cat mailmsg.txt | script.pl, it should work well within your script, allowing you to get further headers easily without writing more code:) 
#!/usr/bin/perl -w

use strict;
use Mail::Header;


my @liste = (<>);
my $header_object = new Mail::Header \@liste, Modify => 0, MailFrom =>
+ "COERCE" ;

my $to               =  $header_object->get('To');
my $apparently_from  =  $header_object->get('Return-Path');
my $from             =  $header_object->get('From');
my $mail_from        =  $header_object->get('Mail-From');

print '         To:  ' . $to;
print '       From:  ' . $from;
print ' maybe From:  ' . $apparently_from;
print '  mbox From:  ' . (split(/\s+/,$mail_from))[0];
print $/;


# our header keys
#    my @headerarray = $header_object->tags();
#    print $_.$/ for @headerarray;
