Your sendmail is configured to listen to 127.0.0.1 only. I don't run
sendmail, so I can't tell you how to fix it, but I thought I saw a
message last night with details.
Basically, NetBSD as shipped does not listen on *any* ports. You need
to reconfigure to listen for incoming connections from other machines.
