Is there an end-user control panel?

[unco]

Is there a control panel for the domain end-user to do things like control his email forwarding, etc? I checked the manual, but it didn't help me. I have a user set up for testing, and I go to https://domain.com:81, and I have tried logging in with

domain.com_unco / passwd
unco@domain.com / passwd
unco / passwd

None of these is working. Unfortunately, I didn't install this and I have no access to anything but the ISPConfig control panel as the admin user. We have probably 25-30 domains on there with users who would like to have a control panel for, well, control over their accounts.

What have I done wrong here? I hate having this feeling like every time I have to do something with ISPConfig, I'm going to cry. I've almost quit my job over it a few times.
