[wp-hackers] What would strip $_POST before 'init' runs?

Is the 403 returned when WordPress receives the POST data? What data are
you posting? 

Do the usual trick of disabling all plugins one-by-one, and switching to
the default theme first. 

If it doesn't help - certain $_POST keys trigger different behaviours in
WordPress. $_POST['name'] is one of them, though will usually give you a
404 rather than a 403. Try prefixing all POST data with the name of your
plugin. $_POST['pluginname_name'], $_POST['pluginname_email'] etc. Any
luck?

Failing that, make sure you check your .htaccess file and virtual host
to check you haven't got any strange configurations in there.

Give a shout if none of the above helps.
