33This callback function is invoked on each connection to the mail 
34filter program.  The callback is to be implemented by the Milter
35application developers.  The name of the callback can be any valid
36function name.  The function pointer is to be assigned to the
37smfiDesc.xxfi_connect and the pointer to the smfiDesc structure
38is passed to smfi_register().
