A few years ago GFI was configured here such that the filters move spam
email into separate spam folders under Inbox, with names such as Bayesian,
SPF, Keyword, and Blacklist. This was done initially so that we could get an
idea of which filters were catching spam, and which were more likely to get
false positives. We are now very tired of having to check all these folders,
so we're going to reconfigure them all to move mail to the user's Junk Email
folder.

My question is this: is there an easy way to delete all of these now
unnecessary folders? Or do I need to tell my users they will have to delete
them manually?

Thanks,
