Hi, thanks for response.
the query i guess was more around how do i referenc the testblock.com domain in a rule? as its not Web traffic i assume i cannot use URL Category etc, so how can i block a whole domain based on domain name, not IP, would need to PA to do some DNS work somehow.
I don't ever recommend using an FQDN object when you're talking about SMTP traffic. If this domain was hosted on Microsoft for example you could end up blocking way more traffic then you intend.
