Insecure $ENV{PATH} while running with -T switch at /usr/local/share/perl5/MIME/Lite.pm

[Mimi Cafe]

I am using MIME::Lite::TT::HTML in my module to send emails and this worked
until I decided to use taint mode. Now Perl is not happy anymore. This is
the first time I am using taint mode, so I am not sure whether my code is
causing this exception or the underlying  MIME::Lite::TT::HTML or
MIME::Lite.

Insecure $ENV{PATH} while running with -T switch at
/usr/local/share/perl5/MIME/Lite.pm line 2689., referer:

In my mobile I have this sub for sending mail and it has always worked until
I switched on the -T.

sub sendmail {

    my (%params, %options, $received_arg);
    $received_arg = shift;
    %params = %$received_arg;

    $params{site_name} = $site_name;

    # Template directory path
    $options{INCLUDE_PATH} = '/var/www/html/templates/';

    my $mail_msg = MIME::Lite::TT::HTML->new(
        From        =>  "$public_email",
        To          =>  "$params{'E-mail'}",
        Subject     =>  "$params{'Subject'}",
        Template    =>  {
              text    =>  "$params{'Text_Tmpl'}",
              html    =>  "$params{'HTML_Tmpl'}",
                         },
        TmplOptions =>  \%options,
        TmplParams  =>  \%params,

    );

    $mail_msg->send;

}



Main program has this codes somewhere.

my %password_reset_mail_parameters = (
        'Fname'     => "$db_fname",
        'Lname'     => "$db_lname",
        'E-mail'    => "$reset_email",
        'Subject'   => "Your  Password Reset",
        'Link'      => "$reset_link",
        'Text_Tmpl' => "password_reset_confirm.txt.tmpl",
        'HTML_Tmpl' => "password_reset_confirm.html.tmpl",
    );

    # Send the requested information.
    sendmail(\%password_reset_mail_parameters);

Any ideas?
