as a former headhunter i'd say that their recruiting dept was just sloppy. there are many reasons for a company to list positions confidentially the most common being that it is a really popular company and people will send applications regardless of the position causing the recruiter to have to weed out a lot of crap and possibly miss someone who is in fact qualified for the position. A close second is that the job to be filled is currently held by someone else who just might come across the ad and then behave in an undesireable manner.

Go ahead and put together a proper letter using their company name. it shows that you took the time to read the whole listing. it shows that you are able to pick out the important details. it shows that you are one of the VERY VERY VERY few individuals who still has the initiative to put together an appropriate letter. most folks just send crappy looking resumes and can't figure out why they don't get more calls.
