Robert,

This is probably because sendmail itself is compiled with the tcp wrappers
libraries (libwrap) and so it's responsible for doing its own logging.
Using the libwrap library only causes an application to use the routines
that check the /etc/hosts.[allow,deny] files and allow or deny access but
it doesn't use tcp wrappers' logging mechanism.  The same is true of other
applications (such as ssh) that can be compiled using libwrap.

In order to see the error messages from sendmail I'm guessing you'd have
to adjust the LogLevel parameter in your sendmail.cf to a higher number,
but I haven't tried it so I don't know for sure.
