In this case, I'll have to agree with Steve Jobs[0] and say: "Change
your folders [sic] name. Not that big of a deal."

Since in a mailbox you will be inevitably storing mails, the -Mail part
is unnecessary anyway.

The same argument that you use to say that dbox-Mails should be allowed
can be used to justify the need for a folder called "zgo0kq2njs". One
just has to be more creative. :-)

And even if it's easy to type with command-completion, I doubt anyone
would have a clue to the purpose of a folder named like this, unlike a
folder with a descriptive name.

Nondeterminism means never having to say you are wrong.
