Upgrading Plesk copies over this file. I've spent over a year customizing and tweeking my header_checks file to almost completely eliminate spam...and now after I upgraded Plesk to 12.5 it's gone.
I realize it's mostly my own fault for not thinking to back up this file...but Plesk really should NOT be copying over that file in the first place. Bad, bad, bad....
