Exim can do this.  In fact I do it.  I never send bounce messages.
Every email is either rejected to SMTP time, or accepted.  This is not
something you could get away with on a heavily loaded SMTP server, but
for an organisation like the one I work for with 300 employees it is
fine.

The package is called Exim4 on Debian.  It is the SMTP server Debian
will install by default.

Exim has a learning curve, but its nothing compared to Sendmail and its
far more flexible than sendmail.  It also has by far the best
documentation of any SMTP server I have used, provided you have the
patience to read it all.  In comparison with Postfix Exim is far more
powerful, but you pay for it in complexity.

Home page: http://www.exim.org/  From there the path to documentation is
obvious.
