I need the following entry for a autoresponder/vacation plugin for roundcube with plesk:

www-data ALL=NOPASSWD: /opt/psa/bin/autoresponder

But the system doesn't recognize www-data as a user. Only the "www" of www-data.

I have Ubuntu 12.04 on my server and I tried it on several machines.

How can I handle this?
