Re: that part: but you don't even have any way to sign this electronically to begin with. They did not provide you with an electronic form/page/whatever to sign, nor an electronic address to send your signature to. The contract required you to personally sign and mail a letter into that P.O. Box, and unless you plan on downloading your signature into that P.O. Box, you don't really have any other option besides paper (unless you get clever with papyrus or something I guess). No matter how I slice and dice it I don't see how the E-Sign act has any kind of relevance here... except perhaps for the part that if you keep a scanned copy of your letter for your records, that'd be considered just as valid of a record as a photocopy?
