crypt++ is not a good choice for transparent, on-the-fly compression;
for that I recomend jka-compr which is also distributed with Emacs now.
But that alone won't work because nnml.el won't operate correctly on the
compressed files.  For that a little bit of hacking in nnml.el is in
order:

- -----
#!/bin/sh

if test -f x-easymenu.el; then
  mv x-easymenu.el easymenu.el
fi

cp nnml.el nnml.el.orig
cat nnml.el.orig | sed 's/\[0-9\]+/\[0-9\]+\\\\(\\\\.gz\\\\)?/g' > nnml.el
- -----

This will at least let nnml work with gzipped mail files for the most
common tasks, allowing jka-compr to do it's thing.  There are a number
of other segments of Gnus' code that operate on directory listings that
this little bit of hackery won't patch, and I wouldn't rely on a brute-
force sed to do it.

The best complete solution, as I see it, is to build a regular
expression from jka-compr-compression-info-list, then modify any code
that references file name in a buffer to include that regexp.  In short,
it's going to be a pain no matter what.
