That might be interesting solution, maildir per time period. But still
fuse zip caches all the data until unmounted. So even with just reading
it keeps growing (I hope I'm not accusing fuse zip here, but this is my
understanding form the code). This could be simply alleviated by having
it periodically unmounted and mounted again (perhaps from cron).

Well, if your granularity will be one archive per year of mail, it
should not be that bad ...
