Applications: Is there an iOS email application that can be unsubscribed from IMAP folders?

I have a lot of folders on my IMAP servers that I do not need every day, they are really files. When using the mail application from Apple, there is no way to cancel the subscription to the folders, so these file folders make my folder look very uncomfortable.

Is there a third-party iOS email application that allows you to unsubscribe from IMAP folders? I see many reviews of email applications and the best, but this feature is niche enough to not qualify a mention.

It is difficult to find an answer with something like Google, because these applications are mostly compatible with some means of unsubscribing from mailing lists, so I receive many false positives (nothing more!).
