Can I blacklist everything and only listen to whitelist?

When I tried to blacklisted 0.0.0.0 and whitelisted what I wanted it wouldn't work. I want to make sure that only a select few IP addresses can use SMTP services.

Did you try the IP range 0.0.0.0 - 255.255.255.255 then whitelist what you want? If that doesnt work, IMO the easier option may just to block all using the Winblows firewall and only allow access from IPs you want to the SM MailService.exe process.
