One of the things I think we lack of a message-ID -> message map. We
have discussed ways to store per-message meta-data outside of the
message file many times, and I don't think we ever came to a conclusion
Weeellll ... I mean, we have the command-line INTERFACE for that, I
think; pick(1) seems like the obvious answer. Sure, right NOW it
trawls through every message in a folder, but there's no reason it
couldn't look at some kind of metadata index. Paul Vixie wrote
something like that a while ago.
so, it's gonna be okay to do:
send -> my-back-post-replacement -> disk
disk -> send -> post
Yeah, that should be fine.
