What is bounce-debian-user ?

["USM Bish" <bish@nde.vsnl.net.in>]

Hi folk,

  Just a small clarification. The mail placed below was received
by me today from "bounce-debian-user".  This was NOT initiated by
me.  Quite surprised to see my name on the LOG (List of Greats!).

  Did others receive this mail too ?
   
  Could someone enlighten me on what this bounce-debian-user is ?
   
  TIA
