| MH uses monotonically-increasing small positive integers to number
| messages within a folder.  Maildir, as I recall, uses large
| pseudo-random numbers, or what appear to be pseudo-random numbers.

Maildir uses the structure folder/{tmp,cur,new}/unique.file.name.
The files are required to be uniquely named, and there is a convention for
the intermediate directories.  djb has a brief but detailed specification
under cr.yp.to somewhere, if you want to google for it.
