This is becoming a bit hacky now, since false is probably never returned anymore.

Maybe moving this exception to the consumer? I mean throwing in line 57 of mail_handler.php

In my understanding the return value false was not handled anywhere anyway, so I didn't mind. I was after throwing a correct error message instead of failing way later with a misleading error message. :)

Simplify logic (thanks Mukunda!)

FTR I gave this last version another test locally, feeding an mbox file with no subject header (which is accepted now without complaints), and bugging input again (which prints a correct error message instead of misleadingly complaining about a missing subject line)
