I’ve followed the Wiki (pasted below) but can’t figure out how to delete the FTP account and keep the email address. Anyone have “better” instructions?
Workaround: Create the mail address not through panel Mail… but instead through Users | Manage Users | Add New User where you can choose a friendly login name from those not already taken on the DH system. Though this method creates also an FTP user of the same name, if you don’t want this you can delete it using […/ Delete] - check the box for user type ftp box not the box for user Type mail.
