I just talked a client through setting up their email client (Thunderbird) so I know it's set up correctly. They have never yet successfully connected to the ISPConfig mail server, so each time they try "Get Mail" the response is "Please enter password", so I know that's OK and I checked the username with them at the same time, exactly as I've entered them in ISPC. dig -t mx gives a sensible response and their web site is working. The error response after clicking OK, having entered the password, is "Sending the password did not succeed. Mailserver myclient.co.uk responded: Login failed" I'm getting earache. Anyone got any balm to salve it?
