Hi, Can anyone explain to me why I would get a perl error in one web browser but not in any others?
All I¹m doing is taking an email address from a form, feeding it to a validation sub that untaints it, then using it with the f option to sendmail. It works fine in Mozilla browsers on both Mac and PC, as well as in Safari on the Mac, but Internet Explorer on either platform gives ³Insecure dependency in piped open while running with -T switch² at the line where I open a pipe to sendmail. ... my $user_email = validate_email_address( param( "Email" ) ); ... open MAIL, "| /usr/lib/sendmail -t -i -f '$user_email' " or die "Could not open sendmail: $!"; The validate_email_address sub comes straight from ³CGI Programming with Perl² chapter 9. It¹s too long to include here but its final line is return $addr_to_check =~ /^$address$/ox ? $addr_to_check : ""; Any ideas on why this might be happening would be greatly appreciated. Best, Erik Rieselbach
