   4  * mailto.php -- mailto: url handler
   5  *
   6  * This page facilitates handling mailto: links in SquirrelMail.  It checks
   7  * to see if we're logged in, and if we are, it refers the user to the
   8  * compose screen (embedded in a normal, full SquirrelMail interface) with
   9  * the mailto: data auto-populated in the corresponding fields.  If there
  10  * is no user currently logged in, the user is redirected to the login screen
  11  * first, but after login, the compose screen is shown with the correct
  12  * fields pre-populated.
  13  *
  14  * If the administrator desires, $compose_only can be set to TRUE, in which
  15  * case only a compose screen will show, not embedded in the normal
  16  * SquirrelMail interface.
  17  *
  18  * If the administrator wants to force a re-login every time a mailto: link
  19  * is clicked on (no matter if a user was already logged in), set $force_login
  20  * to TRUE.
  21  *
  22  * Use the following URI when configuring a computer to handle mailto: links
  23  * by using SquirrelMail:
  24  *
  25  *  http://<your server>/<squirrelmail base dir>/src/mailto.php?emailaddress=%1
  26  *
  27  * see ../contrib/squirrelmail.mailto.NT2KXP.reg for a Windows Registry file
  28  * that will set this up in the most robust manner.
