But "Errors-To:" might do the trick.

These days sendmail lives in /usr/sbin on Linux, only Solaris still puts 
it into /usr/lib if I remember rightly.

I don't want to have to call the sendmail binary directly if I can 
possibly avoid it.
Also, make sure you do *really* thorough input validation on the $toAddr 
and $subject and $content. Can people give an email address of "no-one; 
rm -rf /;" ?

You need to be *very* careful calling sendmail like that, which is 
partly why I don't want to go down that route if at all possible.

Depending on how aggressive you wanted to be with the assumption that the return-path domain is the same, you could also pre-populate that email address and domain suffix in various places in the preferences file during installation as well.
