You'd know better than I, since apparently you've disassembled it, and I
haven't. Without disassembling it myself, which I don't plan to do, I have
no idea what the above even says.

Not that I haven't done this sort of thing in the past, myself. But since
MultiMail is open source, if anyone wants to modify it, I recommend just
changing the source and recompiling it. Though I did notice that you're
using the XT version, and unfortunately that's the only one I've built with
a compiler that's not freely available.

The XT build is also, coincidentally, the only one with some manual
assembly-level optimization; but only in the PDCurses library (not the
MultiMail code per se), and only to deal a little better with CGA. (It will
work if you build it with the standard PDCurses library, but will either
have snow or be slower on a CGA system.)

 KH> (or, with compressing MM.EXE with PKLITE 1.5) ?

It's got an overlay, which sometimes is a problem with executable
compressors. But if it works, it works.

I think I tried it with LZEXE, myself, and it worked OK until it tried to
shell out. That might've been only with swapping on; I don't remember for
sure. (I'm not really even sure it was LZEXE, but that's what I normally 
use(d) on DOS stuff.)
