I found two more articles that give some more details, one shows 3 emails sent to the boy, but it doesn't show the emails the boy sent.

This article adds a little more to the confusion because it repeats that he didn't intern for Foley, but says this -
"Foley's spokesman released this statement: "The emails in question were a response to a handwritten thank you letter from a former page. There have not been any allegations made by anyone except by Tim Mahoney and the Democrats who are attempting to misrepresent a series of innocent communications to prop up a failing political campaign."
A handwritten thank you letter from a former page?

One way or another there is more here than meets the eye and I think we would be able to form a more educated opinion if we saw the original letter/email that started the exchange and all the emails on both sides.
This is interesting:
Update: Foley's opponent has called for an investigation, noting, "It is our understanding that a complaint was filed by the alleged victim, and that complaint should be fully investigated." Foley's office told ABC that "there is no official investigation into the matter and that Foley is only guilty of being friendly."
"Mahoney's campaign spokesperson, Jessica Santillo, said the campaign only recently became aware of the e-mails between Foley and the page."
I can't get my pdf viewer to work on these emails. Can you post the content?
