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