About all you can discover from it is that said box is probably NAT'ed, and gave an EHLO with the 192.168 address on it. For Sendmail, you can fix that information leakage by adding CLIENT_OPTIONS(`Family=inet, Address=0.0.0.0, M=h') to your .mc file (the M=h causes it to use the interface name rather than the host hame on the ELHO). Oh, and that neither address has a workable in-addr.arpa PTR.. ;)
