Hello, I have been tasked with creating a way to block all spoofed emails from getting into our employees inbox/Junk email inbox. We have an SPF record in place (if I did it correctly), but I guess what the question is, and I will give you an example....let's say johndoe [at] xyz works for our company. He at times receives email from johndoe [at] xyz sent to johndoe [at] xyz and those emails are adult oriented in nature. Our email is hosted by another company, my manager is under the assumption that because we have an SPF Record in place that all emails like this should be blocked because they are coming from outside the domain and that the SPF Record should be blocking the email from being received. I guess what my question is, Is there no fail safe way to prevent all spoofed email from coming in, and if there is a way to block this type of email 100% what am I doing wrong. I should also throw in there....we have several network devices and servers that send alerts out when something stops working etc. Any input would be greatly appreciated.
