By default sendmail treats addresses as case-insensitive.  As a result,
the address sent to lmtpd is adam+presentations, which doesn't exist. 
If you want to be able to post directly to certain mailboxes, I'd
suggest using all lowercase names for them.

This will never work.  Essentially 'adam' is your INBOX.

These are correct.

No.

postuser is a dummy userid which "owns" the shared folders.  It doesn't
_need_ to be set, in fact by default it is unset.

To post to this mailbox with postuser unset, you'd send to
+shared.PriceUpdates at ... (note that the upper/lowercase thingy is still
a problem)

If you set postuser to 'bb', then you'd send to
bb+shared.PriceUpdates at ...

I don't know if this makes it clearer or cloudier  ;)
