/^X-Mailer: MIME\:\:Lite/ REJECT I use this one in my Perl mail applications. It's a legitimate CPAN module (see http://search.cpan.org/perldoc?MIME::Lite) that is quite popular. Blocking it will probably reject a lot of email from scripts (of various nature, some probably spam, some not). -- Robin
