Assuming you haven't mixed up the myIP and hackIP parts, this means
something on *your* system/network is trying to contact an smtp server
on what you are calling hackIP. TCP/IP connections are initiated with
a SYN packet. If they are accepted, you get a SYN,ACK packet back.
If they are rejected, you get a RST,ACK back.
Running 'host <hackIP>' might prove enlightening.
