Exits you from MAIL without emptying the WASTEBASKET folder.   Thus,
  if  you  accidentally  issue the DELETE command to delete a message,
  you can cancel the  DELETE  command  by  issuing  the  QUIT  command
  instead  of  the EXIT command to exit from MAIL.  (QUIT performs the
  same function as <CTRL/Y>.)

  If you DELETE a message, press RETURN and enter  the  QUIT  command,
  your deleted message will be in the WASTEBASKET folder.  Whereas, if
  you DELETE a message and press  CTRL/Y  (instead  of  RETURN),  your
  deleted message will remain in the MAIL folder (instead of moving to
  the WASTEBASKET folder).

   Format:

       QUIT
