That doesn't suprise me. I would also expect a few connections from worms/scanners that simply scan the net for open SMTP servers.

You should be able to tell sendmail only to accept connections from specific addresses. The sendmail docs should have this info hidden somewhere.

OTH, typically a server that's not supposed to get connections from the net in general should be behind a firewall, and if it's behind a firewall you should simply block traffic you don't whant before it ever reaches the server.
