The remote host is running a version of PHP earlier than 4.2.2.

The mail() function does not properly sanitize user input.
This allows users to forge email to make it look like it is
coming from a different source other than the server.

Users can exploit this even if SAFE_MODE is enabled.

Solution : Contact your vendor for the latest PHP release.
