The way I usually handle pseudo users via sendmail is to route
them via a dummy subdomain.
So, for example, my main server is 'apollo.backplane.com'. I route
mail destined for 'pop.apollo.backplane.com' to my special pop mail
backend.
My /etc/aliases and other forwarding

NFS isn't involved, but this is on a heavily used webserver.
NIC is a 3COM 3C905b.
Ifconfig up and down works for about 5 packets, that's it. netstat
was showing either errors inbound, or absolutely nothing.
This happens about once
