This error has NOTHING to do with sendmail, and there is nothing that suggests that it might!!! The errors indicate that two MAC addresses are using the same IP address. If you're using a switch, you should be able to trace through it's MAC forwarding table to find the ports attached to these addresses, and then follow the cables back to the devices.
