Hi All, I have my initial mailproxy setup with director through to my initial backend mailstore.? POP3 and IMAP user authentication is working ok on the proxy and the mailstore.? I just noticed when I do a "doveadm auth lookup" on the proxy it appears to give correct results but when I do it on the backend mailstore I get the error below.? Config on the mailstore below.? Any ideas??
