Formular-Verarbeitung funktioniert nicht

[Monica]

"My" selfmail.pl sieht nach Euren Tipps übrigens mittlerweile so aus. Kannst Du bitte einen gnädig-kritischen Blick darauf werfen? Danke!

#!/usr/bin/perl

use warnings;
use strict;

my $Sendmail_Prog = "/usr/sbin/sendmail";

my $mailto = "meine E-Mail-Adresse";

use CGI;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
print "Content-Type: text/html\n\n";

my $query = new CGI;
@names = $query->param;

my $delimiter = $query->param('delimiter');
my $returnhtml = $query->param('return');
my $subject = $query->param('subject');

$subject =~ s/\s/ /g;

my $mailtext = "";
foreach(@names) {
  $name = $_;
  my @values = "";
  my @values = $query->param($name);
  if($name ne "return" && $name ne "subject" && $name ne "delimiter") {
    foreach my $value (@values) {
      $mailtext = $mailtext.$name;
      $mailtext = $mailtext.$delimiter;
      $mailtext = $mailtext.$value."\n";
    }
  }
}

open(MAIL,"|$Sendmail_Prog -t") || print STDERR "Mailprogramm konnte nicht gestartet werden\n";
print MAIL "To: $mailto\n";
print MAIL "Subject: $subject\n\n";
print MAIL "$mailtext\n";
close(MAIL);

print "Location: $returnhtml\n\n";
