SPF records have a strict limit of 10 DNS lookups to prevent excessive DNS queries. Exceeding this limit can cause SPF authentication to fail, leading to emails being rejected or marked as spam.
I get it. It's 2025. You should be able to do anything on your phone or tablet that you can do on your laptop.
Except this site. I think the design is best left for wider screens. Besides who wants to look at DNS records on a tiny screen?
So rest easy for now and load us up when you're back at your desk!
