In the settings of the Plesk Email Security extension, in the "Server Settings" tab under the "Advanced" section, is a setting titled "DNSBL" where I can enable various DNS block lists:
How does this relate to the general "Mail Server Settings" / "Server-wide mail settings", which in the "Settings" tab has a setting titled "Spam protection based on DNS blackhole lists"?

Do they have the same function? Would it be best to disable the general setting when I'm using the Plesk Email Security extension?
In general, I haven't been able to find technical documentation about the Plesk Email Security extension and its settings. This would be much appreciated, especially since it's a paid extension.
