Delay makes your simultaneous connections number grow because time you spend
for serving a connection becomes greater with delays. Defer would work better
here - it does not require to hold a connection but reduces spammer's sending
speed. Just add hosts you want to delay connection with to your greylist and
do not let them send more than 1 message per 2 or 5 minutes.
