How Reliable Is an IP Address Reputation Check for Security? or Should You Worry About Your IP Addres

Thanks for all the advice, y’all! Didn’t realize how many false positives were a thing.

I checked MXToolbox like a few of you suggested, and turns out I’m only on one minor blacklist. Gonna try delisting and see what happens.

Also, good call on the DNS settings—totally forgot about SPF. Gonna set that up today. Appreciate the real talk!
