That is helpful, but it seems then, that it is telling me there is NO way to successfully pass a user-supplied From address to Mail::Mailer, if that module uses system, exec, or a piped open. I say this because in untainting an email address supplied by the user, you risk wrecking valid addresses since just about any character may exist within a valid address. I used Mail::Mailer because of its proported feature of avoiding the shell, in the interest of security. I don't believe that Mail::Mailer uses a piped open, as it is the module's goal to keep the message being sent far away from the shell. But the exec one seems a little tricky to get around.

I could supply a hard-wired From, and then pass the user's supplied From through the body of the message, but even that must pass through Mail::Mailer.

Surely I am just not seeing the simple solution. ;)
