Why SPF matters for a plumber

We moved SPF for a plumber to a provider that supports DNSSEC. It added five minutes to the migration and closed a class of attacks they did not even know about.

There is a difference between a site that loads and a site that works. SPF is part of the second category for a plumber.

We found a booking tool that demands an account during a routine check of SPF. The site had been leaking referrer data for six weeks before anyone noticed.

Six months later, a plumber asked us to look at something unrelated. While we were in the panel, we noticed a booking tool that demands an account had crept back. We fixed it before it caused trouble.

The vendor promised a plumber that SPF was handled. We verified: it was not. Trust but verify has saved more uptime than any product we have used.

Search consoles like honest sitemaps. Every loc should be a document. Reserving ten thousand empty shells and hoping Google does not notice is not a strategy for SPF.

We have seen agencies charge a plumber for a yearly SPF audit that consists of a screenshot and a paragraph. Ours is a working config file they can apply themselves.
