With my previous cpanel host, the “Deliver to folder” option on Mail filters provided an autocomplete feature that helped you find IMAP folders and correctly name their paths (with the “INBOX/foldername” kludge that Cpanel always seems to uses). Furthermore there was an option to test filters so you could make sure they worked how you meant.
Your filter interface not only is missing the feature to test, but it doesn’t even have any documentation (help) at all!
For example: when using the “matches regex” option in the conditions, am I supposed to surround my regex with slashes? And also, using “Deliver to Folder,” how am I supposed to pick a folder to deliver to? What is the syntax for this? And I assume it’s hopeless to ask for something to parse that and make sure the folder exists, I’m guessing if I get it wrong (leading slash? Yes? No? Include the “INBOX” part?) then it’ll just eat my email right?
