which package has a binary like this sendmail one in exim?

[Britton Kerin <britton.kerin@gmail.com>]

Hi folks,

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

  brittonk@brittonkerin.com [~]# sendmail --version
  Exim version 4.76 #1 built 26-Oct-2012 16:41:54

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?
