It sounds like the e-mail reply you received was an automated response that was set up for the sole purpose of letting applicants know that the company at least has your resume in their system. I received more than a few of these when I was sending out my resumes, also. The signature on the bottom of the e-mail could just be the signature that is programmed into all outgoing e-mails from the person who set up the response. Most likely that person is the actual person who will be contacting potential candidates for interviews.

You really have nothing to lose by giving them a call to verify that the position is still unfilled and that you are still being considered. I am sure with a start date that is a couple of months away that it is still unfilled. At the very least you will get a voice mail and at the very most you will be able to talk to the individual and maybe she will even give you a quick phone interview.

The company may also have anticipated that there would be many resumes sent to them and have provided themselves with a timeframe consistent with that probability and their anticipated start date for the position. If they are receiving a boatload of people applying, then your contacting the human resource individual will at last keep your name in his/her mind and when it comes to the culling of candidates and your resume gets looked at, more attention may be paid to you you because you showed that tiny bit of extra interest in the company and position.
