I have a problem with one particular host that is making SMTP connections
with us and then just hanging on, eating up lots of CPU time and eventually
making multiple connections which block our local sendmail from running the
queue.  Is there anything I can set in sendmail.cf or elsewhere to cause
connections from this host to be refused or to limit the time length of an
incoming SMTP session?

We are running U Toronto's sendmail on a Pyramid 9815.
