nnimap usage model

[David Abrahams <dave@boost-consulting.com>]

Hi, 

I was convinced to try IMAP by a friend who uses Mulberry to read mail
(and wishes he could edit in gnus/Emacs!)  His usage model sounds like
it would suit my needs well; basically he keeps a local copy of all of
his messages for fast searching, and so that he can easily work
"unplugged".  I'm having a hard time replicating that, especially the
unplugged part. I do have:

(setq
      gnus-cacheable-groups "^nnimap*"
      gnus-use-cache t)

But it seems to go back to the server a lot, especially to retrieve
headers.  Also I can't look at my messages at all in "unplugged" Agent
mode.  What am I missing?

BTW, I also wonder if it's possible to get GNUs to cache its notion of
each group's headers (summary buffer) between sessions.  My other
programs (Mulberry, Outlook Express) do that and that's one among many
other factors which seems to make them feel a lot more responsive than GNUs.

Thanks in advance,
Dave
