Anyone using PHPList on Shared Server?

I have successfully installed PHPList on my shared hosting account at Dreamhost. Unfortuately I haven’t found a way to get the “Embargoed” or “Scheduled” message feature to work. Has anyone using PHPList on Dreamhost got this feature to work properly?

I have a subscription-based e-mail that is sent on a daily basis. I need to know how to go about setting this up. I searched the forum here and have great difficulty finding anything. Also, I tried the PHPList forum and have had difficulty finding a solution that will work at Dreamhost.

Please help!
