Mail.app & non-standard IMAP folders?

My domain provider just changed their email policies and now has a folder named "OldMail" as part of their email folders for older email.



Well, I would like to access this folder [via IMAP] in mail.app.





Is there anyway for non-standard IMAP folders to show up in Mail.app? [because I don't see it, even after I "synchronize"]







Any help would be great!!
