I've been doing a lot of work with the Whole IMAP thing... on your first item, one way is to test it in telnet to see if you're calling the right mailbox.
it could be something as simple as it being a sub-folder under your inbox which would make it INBOX/foldername
If you do telnet list it may help you see what it's seeing ..
TELNET hostname 143
? LOGIN username password
? LOGIN domain/username password
? LOGIN domain/username/alise password
? LIST "" "*"
(You need the question marks)
