Evo can actually do this, but the ui wont let you.  Not sure how we
could make it do it either, without the awful outlook filter editor with
a million popups.

I wonder how we could do this in the ui (and the backend for that
matter).  It would be handy, and it's often been asked for.  Some sort
of nested tree-ish display I guess.  Perhaps a 'and' and 'or' 'rule part
type' which then has a sub-list of rules inside it ...

What were they thinking ... perfect candidate for an extension.


Actually mainly i'm curious as to how exchange defines its rules - are
they somewhat sieve (and for that matter, imap-search) like, in that you
have a bunch of specific tests/checks with and/or/not boolean
containers, or are they a bit camel-like in that you can do
almost-arbitrary expression on almost-arbitrary values.
