My girlfriend is always talking about a movie where a boy travels by riding on a postage stamp, or travels by mail or something like that. She can only remember this part of the movie and she doesn't know the actor or title or whether it was animated or not? Does anyone know if this is a real movie, or is my girlfriend just crazy.:)

Nope, Your girlfriend is not crazy.

The Movie is Tommy Tricker and the Stamp Traveler. And it stars Lucas Evans and Anthony Rogers.
