My understanding of Sendmail is that the main process, running as root, vforks a child that 
setuid's to "smmtp" for each incoming SMTP connection, there is a limit on how many 
children are forked and an overload condition results in the incoming port 25 connection 
failing. Nothing in this chain of events results in a child Sendmail process failing with an 
"overload" abort. This might only happen if the configuration files do not match the network, 
CPU and memory resources of the mail server. I would not think a milter author should worry 
about this lack of knowledge by the person configuering the mail server.
