When users try to send an email via MailEnable, they receive the following error: Address Resolution Problem The message you attempted to send did not have any valid recipients. You must specify at least one recipient to a mail message. Please click on the 'Continue' button to modify the recipients of the message. When continue is click, it says: Message has been deleted and no longer exists. When trying to delete a message, all it does is refresh the screen. Messages are not being marked as read. I am think it is a permissions issue. I ran the Plesk Reconfigurator and Correct Disk Permission, but it did not help. Any help would be greatly appreciated. Thanks in advance.
