That's now far clear for me! As stated in a previous message replying to a
Mark's post, I make a mess interpreting wrongly several messages from our
services provider and some googled information. Ezmlm was behind the scene.
Sorry for the misinformation!

That's correct: messages are stored in separated files ordered in
subfolders named with a series from 0 onward. 0, 1... each subfolder holds
one hundred files, each of them with a complete message. I think the global
order could be provided by the subfolder order plus the name of each file
within a subfolder.
Mark's reply contents a simple line to get some concatenation. I'll play
with this idea and report back!

Most lists are public, so privacy is not a concern! You can find here the
complete folders' structure for one of the lists...
