How will the IMAP account behave with the current mail_location setting below?

mail_location = mbox:~/mail:INBOX=/var/mail/%u

That is, where will the IMAP account's mail "go"? Right now it goes to /var/mail/[localusername]. Maybe incorrectly, I assumed IMAP required Maildir format? How are folders handled with this setting?. The one IMAP account would be used for spamassassin training, it would need 2 shared/public folders ("spam", "ham").

IMAP is a protocol: it does not dictate the storage format. You're free to use whatever format dovecot supplies a backend for, including mbox or maildir.

What your mail_location specifies is that the INBOX is a mbox (not maildir) formatted file located at /var/mail/[localusername]. Other mailboxes are located in ~[localusername]/mail/* (also mbox formatted).

If the IMAP account requires 2 externally supplied mailboxes or folders (spam, ham) accessible via IMAP, you'll either have to copy them into the IMAP user's mail/ folder, or setup special name spaces that maps to the mailboxes' path. The mailboxes need appropriate file permissions so that the IMAP user can access it.
