malformed header from script. Bad header=Recipient names must be specif:

the from page is http://msdcomputing.com/form.html

the comments.pl script used to send the mail is:

require('/var/www/cgi-bin/cgi-libs/forms-lib.pl');

# Read input from the form.
%input=&GetFormInput();

# Set the recipient, message, and sender.
$recipient = $input{'address'} || "mikesd at msdcomputing.com";
$message = $input{'comments'};
$sender - $ENV{'HTTP_FROM'} || "mikesd at msdcomputing.com";

#Specify the mailer
$MAILER = "/usr/lib/sendmail";

# Compose and send the mail message.
open(MAIL, "|$MAILER -f$sender $recipient");
print MAIL "To: $recipient\n";
print MAIL "Subject:  Comments on your web site\n";
print MAIL "\n";
print MAIL $message;
close (MAIL);
