Hi,
To ensure that you
This could be your ISP. Try a traceroute and see if your first hop out of
your gateway is on a 10.x.x.x net. I know some of the cable ISPs in the US
use a 10.x.x.x subnet between their subscribers and the public networks.
Ifthis is the case, your ISP is could be using the POP3 port to test for
First off you should make sure its not internally-generated traffic.
Then you should make sure your router and your ISP's router are not
passing those packets. RFC X (requirements for ip routers or
something) requires that, I think.

It's not a routable address (in the sense of Internet routable) - read RFC
1918.
However, it can be used - perfectly properly - within your ISP's area of

uses for their cable modem system is a 10.0.0.0/8 space assignments
