[RCU] White List

For reasons too depressing to recite, I was required by my employer to move my personal e-mail from its previous, cosy environment to something more "Suitable." Since I already have material on Startlogic, I elected to make Stsrtlogic's RoundCube my default personal e-mail, and as such, it is working very nicely. However, the volume of incoming garbage is annoying. On my previous e--mail host, I maintained a White List of users or domains from which I was willing to receive e-mail. Any source not on my white list received a polite message asking them to request access to my e--mail.

Is there a similar feature on RoundCube?
