I recently migrated from emacs VM to mu4e. Using
mb2md.pl I successfully (well, modulo a few tweaks) reformatted ~140,000 emails. All good, really.
However, because of the single-file format of VM, and to keep that size manageable, I had several mail files all relating to a single aspect of my job. These got transformed into separate maildir directories. I would like to consolidate these directories into a single one, not just to be anal about it, but because when moving emails auto-completion can't resolve the destination smoothly with my naming conventions.
My question: can I get away with a single
mv command to reposition all those related emails in a single maildir, followed by
mu index, or do I need to manually move them all within mu4e?
