Johnny Cash recorded a song that's relevant. Wikipedia has a lengthy entry full of unisex names from around the world. Surely, someone, somewhere in the world makes up a new name every day. Based on a person's name alone, there's no way to assign a salutation with unattended automation without substantial and sustained effort and still not eventually fail in a potentially easily embarassing way. Much easier and safer to provide a field for users to fill in their own desired salutation. Bonus points if it's a text entry field instead of a dropdown list, for the same reasons that #24 through #29 are listed in the parent article.
