I am looking for the correct way to add postgrey to my system but whitelist everything except for com, org, and net domains. Most of my spam is from .info domains.
There seems to be no way to only go after certain domains, instead postgrey wants to go after everything except what you whitelist.
So my idea was to whitelist .com, .net, .org, .gov, and a few others while greylisting the rest.
The syntax for the files want FQDN, email addresses, or domain names.
But How do you just add a .TLD?
this sound right?
