It looks like the mail filter plugin
[https://wiki2.dovecot.org/Plugins/MailFilter] is almost exactly what I
want, except for this:

Is there any prospect of those code changes being made, so that the
filter can modify mail contents?
There's no indication in the docs or the code of what would break if the
contents were modified, but I'm guessing indexes and caches would be out
of date and would need to be rebuilt? Is it possible to just disable
those? I don't need high performance.

existing emails and new emails as they are received (though anything
that works for existing emails can probably just be run again for new
emails.) My mail storage is currently mdbox, but I could migrate to
another format if that helps.
