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

11 Running 'host <hackIP>' might prove enlightening.
