The ones I have listed are free to use, although some of them will require you to pay for a subscription if you make a large number of queries per day. And yes, Barracuda’s RBL requires you to register your IP address with them, but well worth it since their RBL is very good. The only paid RBL that I’m aware of is dnsbl.invaluement.com.

Are all RBLS free to use? Or do you have to register/pay for them? I know barracuda does require a register. Do these settings also protect against spam being sent from the server?

That log message indicates that smtp.secureserver.net won’t talk to your host, so it sounds like a godaddy issue since it won’t talk to one of its own servers. I’m assuming there are multiple sites hosted on that same IP that you have & maybe another customer is sending out spam (maybe unknowingly) or doing something else that has caused the mail relay to refuse accepting mail from that host.

Norm, are these rules for intending do not receive spam only? Or they also help do not relay or send spam somehow?
