It's weird. This took me a while to find, too.

Pine's normal Folder-Collections *don't* look at INBOX. I dunno why. You have to turn on "enable-incoming-folders" in Pine. Then, if you look at the Folder List in Pine, you'll see a Folder-Collection "Incoming-Folders".

Your default "INBOX" should already be in there, and you can (A)dd additional inboxes.

It will ask for mail server name (I use something similar to this as well: hostname/user=username@virtual.doman/novalidate-cert), folder name, and a nickname. A folder name of 'INBOX' (without quotes) works fine.)

If the account is on the same server as other accounts that you are checking with that Pine instance, you have to be sure to use the /user=foo syntax or Pine will assume the same username. :-/

So if you want to read both the INBOX from an account and the other folders in that account, you set it up as a folder collection *and* (A)dd it into the Incoming-Folders collection.
