It looks like someone is retrieving mail from 207.253.6.3. The port
numbers tell you a lot. The connection is from the pop3 port on
207.253.6.3 to an unprivalaged port on 24.203.96.163. Is someone on
your network getting mail using Fetchmail, or something like Netscape
from a site outside your network?
One thing to keep in mind, input rule messages will show the IP of your
firewall as the destination address when they come from the internet.
This is because they have not hit the masquarding rules yet.
