  snail mail
       n : any mail that is physically delivered by the postal service;
           "email is much faster than snail mail" [ant: electronic
           mail, electronic mail, electronic mail]

  snail mail
       
           (Or "snailmail", "smail" from "US Mail" via
          "USnail"; "paper mail").  Bits of dead tree sent via the
          postal service as opposed to electronic mail.  One's postal
          address is, correspondingly, a "snail (mail) address".  There
          have even been parody USnail posters and stamps made.
       
          The variant "paper-net" is a hackish way of referring to the
          postal service, comparing it to a very slow, low-reliability
          network.  Sig blocks sometimes include a "Paper-Net:"
          header just before the sender's postal address; common
          variants of this are "Papernet" and "P-Net".  Note that the
          standard netiquette guidelines discourage this practice as a
          waste of bandwidth, since netters are quite unlikely to
          casually use postal addresses and if they really wanted your
          snail mail address they could always ask for it by e-mail.
       
          Compare voice-net, sneakernet, P-mail.
