Evolution HEAD doesn't notice updates to IMAP folders unless you click on
them.  For example, it won't notice that there's new mail in a folder, so
to check for new mail, you can't hit send/receive, but rather you have to
go through and click on each individual folder.  This is pretty painful.

This worked in evo 1.4.

On either Send/Receive or in the "Check for new messages every n minutes"
operation, Evo should do a recursive check of all folders visible on the
IMAP server. 

I see this behavior with both uw-imapd and courier imapd, over SSL.
