If it's a machine performance issue then you could try limiting the number of children: # maximum number of children we allow at one time O MaxDaemonChildren=30 If it's for a major mail server then I would _not_ recommend this, as once the limit is reached all connections to port 25 will be refused. I had a play with this the other day when someone decided to forward 150Mb+ of their email from work to their home account, and it was severely loading the system. Otherwise, you could ipfw deny the IP [range], or do it at a higher level with sendmail as another poster suggested.
