In an old google post I found the following, which explains why I have
been unable to get rid of cached IMAP articles.  When you "expire" or
"delete" articles, this deletes the server copy of the article.  But
cached articles are never deleted unless you explicitly remove them
from the cache ala M-*.  While I can imagine some reason for this, how
do I both:

- cache all articles that are on the server
- cause B C-M-e (delete all expirable articles) to actually delete the
server AND cached copy of an article?

The default caching policy makes sense for ephemeral messages on NNTP
groups, but IMAP is persistant so it makes no sense to cache an
article that you have deleted on the server.
