+A note on PHP 4.3.x
+===================
+
+While the developers realize that PHP 4.3.x is the "latest and greatest"
+version of PHP to be available, SquirrelMail has not been extensively
+tested with it. There may be potential session issues with PHP 4.3.x,
+and PHP by default has a session warning which will need to be disabled
+if you wish to use it with SquirrelMail.
+
+Put simply: The SquirrelMail team does not recommend the use of
+PHP 4.3.x with SquirrelMail at this time.
+
+SquirrelMail will put a large ugly warning about the use of PHP 4.3.x on
+the login screen unless you add "$shootMyFootOff = true;" to
+config/config_local.php, or downgrade PHP.
