Testing frameworks hold on to all messages for as long as a test is
running, and store whatever mappings they need in RAM (like Python
dicts) for the duration; this is a matter of minutes (not months), and
has no UI, no provision for recovering from errors, etc.

You could do that, and it would be especially easy if using a friendly
mail-store format (like Unixish mbox format, not Outlook .pst).
