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