That's a very good call. I'm not sure the universe is up to creating that many directories. 99 levels of 99 directories in 99 directories is a LOT of directories: 99^99 = 3.69729638 × 10^197

Allowing for the creation of one directory per nanosecond (unrealistically swift, 99^3 in 23 minutes is nearly 1.5 milliseconds) and suspending all other physical limitations, it would take:
99^99 * 10^-9 / 60 / 60 / 24 / 365 = 1.17240499 × 10^181 years

Many, many, many orders of magnitude beyond current estimates of the universe's age.

As to your original problem, a recursive shell function would probably be the simplest approach.

NAME
new - report on folders with new messages fnext - set current folder to next folder with new messages fprev - set current folder to previous folder with new messages unseen - scan new messages in all folders with new messages SYNOPSIS
new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help] fnext is equivalent to new -mode fnext fprev is equivalent to new -mode fprev unseen is equivalent to new -mode unseen DESCRIPTION
New in its default mode produces a one-line-per-folder listing of all folders containing messages in the listed sequences or in the sequences listed in the profile entry "Unseen-Sequence". Each line contains the folder, the number of messages in the desired sequences, and the message lists from the .mh_sequences file. For example: foo 11.* 40-50 bar 380. 760-772 824-828 total 391. The `*' on foo indicates that it is the current folder. The last line shows the total number of messages in the desired sequences. New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order. Override this behavior by provid- ing foldersfile containing the pre-sorted list of folders new should check, one per line. In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively. In unseen mode, new executes scan sequences for each matching folder. FILES
$HOME/.mh_profile The user profile PROFILE COMPONENTS
Path: To determine the user's nmh directory Current-Folder: To find the default current folder Unseen-Sequence: The name of the unseen message sequence SEE ALSO
