Yes, that's an unfortunate thing indeed.  I am not sure if nnmairix can
be tuned a bit to use the agent.  I download most of the groups I read
in a local Gnus agent cache, and then read them from the cache.  So I
will try to see if nnmairix can 'peek into the cache' instead of
fetching the articles over the wire.
