Ahh, I hadn't read that yet.

What I remembered was in section 3.6:

By default all these message files are helf in a single directory
called input inside the general Exim spool directory. Some operating
systems do not perform very well if the number of files in a directory
gets very large; to improve performance in such cases, the
split_spool_directory option can be used. This causes Exim to split
up the input files into 62 sub-directories whose names are single
letters or digits.

While that doesn't directly contradict the above, it makes things a bit
unclear...

Sorry for the misunderstanding.

Cheers,
