It seems to me like the right way to handle your situation would be to 
adjust the QueueLA and RefuseLA parameters on the HP/UX box's sendmail.  
That way you fix the situation no matter what the source of the 
bombardment is, as opposed to just fixing it from your Mailman server.

>From /etc/sendmail.cf on a generic system:
# load average at which we just queue messages
O QueueLA=8
#
# load average at which we refuse connections
O RefuseLA=12

Just change QueueLA to, say, 1 and RefuseLA to, say, 2 or 3.  Once the 
load average drops back below the threshold, sendmail will start 
accepting/delivering mail as appropriate.

Just a thought.
