That's two questions.  :-)

1)  They're actually special files - these ones are sockets that
    actually live on the file system (as opposed to sockets that
    live in the networking namespace).  Another type of special
    file is a pipe.

2)  Yes, it's safe to ignore them.  Typically they're regenerated
    by the application that created them in the first place (in
    this case, most likely Postfix).
