IMAP Splitting with multiple mailboxes (was Re: Spam splitting and multiple nnimap methods)

[Timothy Brown <tim@tux.org>]

Can someone provide a better explanation of how IMAP spam-splitting and
standard splitting, particularly with multiple servers, interact?  i've read
the manual and the sections on virtual server spam splitting but i'm still a
little lost, particularly in combinations using :spam-split.

In short:

 1) I am using fancy splitting;
 2) I have spam-split as part of my splitting rules;
 3) I am not specifying any nnimap+host:folder definitions. 

Do I need to be using the virtual server stuff, as 6.5.1 in the Manual
suggests?  If so, how does this work with fancy splitting?

Thanks,
Tim
