[TYPO3] bf_xml_for_flash modifies my mailform

[Bartosz Aninowski]

This is verrry strange.
When I add normal mailform to a page it looks like this:
<form action="job/thank-you.html?type=444" 
name="d76cb3d001ad577e4d7e320e69e45009" enctype="multipart/form-data" 
method="post" target="bf_xml_for_flash" onsubmit="return 
validateForm('d76cb3d001ad577e4d7e320e69e45009',
Check target and acction. How is it possible that  bf_xml_for_flash modifies 
mailfrom??
