OK, as I'm going through the media links thread I'm finding some info. that may shed some light on the possible sightings information, and other things. Keep in mind that reporters do not always get things right especially if there are conflicting reports.
First, vasportsmom's post here contains info. as reported in the media about several possible sightings in the first days of the searching:

One of the possible sightings was found to have been a jogger (the rescue workers), and it is thought that the 3rd possible reported sighting was likely the same jogger. (see above comment for the various news links)

At this time, the La Plata County Sheriffs Department said Mark Redwine is not a suspect in his sons disappearance.
They are conducting a through search of the home to because it was the last place his son was seen.

OK, that's all I can add at this point about sighting and whether or not they were completely ignored, or investigated and dismissed - as in other cases there are lots of tips, leads, and possible sightings, and I have no reason to believe they completely ignored the mail carrier's report to them.
Still trying to get to the transcript of the DP show... Sorry it's taking me so long. Got side-tracked seeing some of those first posts on the media/timeline thread, and I'm having trouble with pages not wanting to load for me. Will check if anyone found it first when I hit "post".
