Woo. A security risk, eh? That sounds like admitting their code is
crap and that they don't check the memory they're writing to.. bad.
I'm glad these boxes are on their merry way to the scrap heap.

Sadly, I'm not that fortunate. The clients are end-users (and their
correspondents), using all kinds of broken MUAs. (The sheer number
of distinct M[TU]As out there that are broken in some way never ceases
to amaze me.)

That's a possibility, like the transport filter Tom suggested. I'm
hoping I can find a less expensive way to do it, though. But it's nice
to have some approaches to fall back to.
