Nope.  Email performs a handshake, it does not probe an entire system to
communicate.  If it receives no response on its connection attempt, it
ceases activity.

A gentle port scan on every port it checks also performs a handshake.
It's TCP for god's sake.  In fact, if you have a firewall blocking access
to a port (DROP) that is not allowing the RST flag to get sent back to me,
are you not in violation of your handshake scenario?


Nope.  The portscan is not a standard service connection.  It is a shotgun
approach to inspect my system without my permission.  SMTP, HTTP, FTP,
HTTPS, SSH, TELNET, etc, are all standard methods of initiating specific
forms of communication.  The portscan is not.

The portscan is a tool for troubleshooting, security inspection, and
precursor to attacks...all depending upon somebody's motivation.  When it
isn't me, or someone I've authorized to perform such a scan, the
motivation is an unknown factor.  As such, it is tresspassing, as it was
done without my permission.
