The original sentence I got from the provider said, translated to English:
the format is vpopmail (qmail - courier). I must recognise that I'm not
able to reconstruct the pathway that has led me to say that we were using
Maildir. Ezmlm was the actual software that created that lists. Both,
regular maildir account subfolders and ezmlm subfolders are stored in the
same folder in the archives structure. I think this was the reason why I
interpreted all of them are Maildir subfolders.

Here you can access to the whole structure of one of the subfolders...

http://datasource.idisantiago.es/r.users/

Here the indexes of subfolders 0 and 1 (ISO Latin 1 encoding required for a
correct rendering of all the characters)...

http://datasource.idisantiago.es/r.users/archive/0/index
http://datasource.idisantiago.es/r.users/archive/1/index

It looks like each subfolder in the row within /archive holds a maximum of
100 messages numbered from 0 to 99.

Each file within subfolders 0 and 1 contains a complete message, including
attachments (this is a guess, as files' size ranges from few Kbs to several
Mbs).

The link above gives access to a whole subfolder!

Once again: thank you for your help and, please, accept my apologies if I'm
not able to provide accurate and clear information about the issue: at
least for me, it is by no means easy to sail this sea plenty of different
standards!

All the best,
