[exim] which package contains the sendmail binary?

Hi folks,

I know exim sometimes contains a sendmail binary because on one system I
get this:

brittonk@??? [~]# sendmail --version

But on my debian box (current stable distribution), there is no
/usr/bin/sendmail binary even though I have exim installed. There is a
/usr/sbin/sendmail binary, but it doesn't seem to be the same one because:

$ /usr/sbin/sendmail --version
exim abandoned: unknown, malformed, or incomplete option --version

I also found /usr/lib/sendmail but it does the same thing.

Does anyone know what debian package provides the /usr/bin/sendmail program
or its equivalent like on the first system described?
