smartlist debugging

I am running RedHat enterprise server 4 and I am having difficulties getting smartlist to work. Procmail and Smartlist appear to have installed properly and I am able to create lists, however, when mailing to the list it does not send the email out. I've checked that email can be sent out the smartlist account and it works. I believe there is a mis-configuration somewhere, but I am unable to locate it. Has anyone actually been able to get this to work with enterprise 4?
