It can only be done in sendmail. sendmail stops accepting mail if your load 
average exceeds 9 (by default). You could drop this to a lower value. You 
can also stop accepting mail when you reach a number of children. I'm not 
sure if you can stop accepting mail with a certain queue volume. Have a look 
at the sendmail config options. ->
