Note that the "sendmail" path and options should be configurable,
someone might want to use /var/qmail/bin/qmail-inject for example, and
it should allow wrapping the thing up in /usr/bin/env should that be

I'd like to have a closer look at how you invoke the MTA so as to
prevent shell metacharacter abuse.

Don't use system(). Don't use execlp() or execvp().  (Better force the
user to set the fully qualified path in the configuration file.)

Use fork() and either of these: execv(), execl(), execle().
