I can't say that I know every single line of nmh and MH code since the dawn of time, but I've been in and out of it a lot. The assumption that you can represent email lines as C strings has been embedded in nmh and MH for as long as I can tell. Such emails don't work with nmh, and they probably don't work well with other MUAs either. Okay, fine, "don't work" is a bit of an oversimplification; it seems like those lines will be silently truncated at the NUL character, so they probably "work" fine and you just don't notice the NULs. --Ken
