Early versions of the GNOME Evolution email program used an abstraction layer
for the local mail storage. This allowed the mail program to present the user
with a virtual view of mail storage folders that looked familiar. But, under
the hood, the actual mail storage could be done via maildir, mbox, mh, imap, or
whatever. What was really cool is that the user could right click on a folder
and switch that particular folder from one format to another at will. So I
could have my spam folder be mbox format, which made it easy for me to submit
the whole folder to spamassassin periodically for learning. And I could have my
other folders in maildir format, which was safe, fast, and had no mail or size
limits to worry about. 

Sadly, Evolution later dumped this scheme in favor making all local storage in
mbox format, imposing the usual limits, slowdowns, and corruption dangers. It
was dumped not because of any technical issues but (I think) because of the
overall GNOME project's drive to remove user configuration options and choices
where ever possible to "simplify" things for dumb users. I've since figured out
a less than ideal workaround that allows me to sort of use maildir with the
current version of Evolution but it's not pretty. I'd switch to Thunderbird
instantly if it provided a flexible local storage system like the Evolution
v1.4 era client had.

The code probably still exists somewhere and was GPL'd so maybe it could even
be reused as a starting point for a Thunderbird mail storage virtualization
layer?
