The Mailbox structure usually is not changed that often. Maybe just 
provide a way to dump/export the current mapping to a specially formatted 
text file and a way to manually load/import a provided dump file.

This way, administrators can configure daily cron jobs to dump the current 
mailbox state and if a mapping really gets lost, a "pretty good" mapping 
could be reconstructed without any runtime penalty.

Yes, for example, with the option to overwrite this synthesized mapping 
with the latest dump.

Greetings,
