OK.  I think, while you're at it, some documentation is needed of what
the "Options" field means when setting up nnir there.

Ah, thanks!

Not useful enough to justify the slowdown.  Seriously, it's **really**
slow.  I have too many groups.  I mostly don't sort messages anymore;
most of what's there is legacy stuff.

I'm familiar with them, thanks.

Yes, my problem is how to specify the "server" element.

Inasmuch as it describes my server, I thought it would help you describe
what should go in the "server" element.
