Guys I have search the forum but can't seem to find the right answers. I have ISPConfig 2.2.18. Everything has been running fine until just 2 days ago. I have noticed mail comes into the Mailboxes and after 2-3 minutes it disappears as though its been deleted from the server. My email Client (Thunderbird) is configured to leave all mail on server, so I am at a loss. I have run the Database Optimising and repair checks in ISPConfig, but to no avail. I have also deleted main offending email address and recreated, and to no avail, any help would be appreciated greatly. Thanks Roy.
