what should be in a vmail folder?

[crypted]

Okay, I was using ISPC2 for a few years and it wasn't using the same mail service as ISPC3 uses now. However, all mail was moved over and imported. I believe it was originally mbox and then transferred to mailbox.

Currently, I have this:

I end up with a bunch of random folders in my IMAP Outlook account that I have to hide. However, my IMAP cellphone software picks up every directory in vmail and calls it a subfolder of Inbox.

I'm thinking there's a bunch of useless crap here that needs to be removed.

Thoughts?
