[MlMt] Showing all messages in subfolders

[Jon Nall]

Hi all,
I have an IMAP folder (parent) that contains subfolders (children). When 
I select the parent folder I'd like the message list to be populated 
with the aggregation of all mails included in the children folders (and 
grandchildren, etc). Is this possible?

It's my understanding that the folders aren't truly hierarchical on the 
IMAP server itself (that hierarchy is communicated via a naming 
convention), so I expect this would be a client feature.

Thanks,
nall.
