OK, this is annoying me.  From what I understand the table amavisd.wblist is related to a USERS white/blacklist right?  I may want to look into that in the future but for now I just want a general whitelist and blacklist.  Where do I add those?

Looking for a domain or global level.
So for example, how do i block everything from a ".rocks" domain?

I do not have Admin-Pro.

Thank you!
