configurable, drop-in replacement for sendmail.

<description>
<p>Vulnerabilities have been discovered in Exim’s implementation of
set-uid root and when using ‘perl_startup’. These vulnerabilities
require a user account on the Exim server and a configuration that does
lookups against files to which the user has edit access.
