title: How to fix SPF issue
body: <p>So I'm using mail-tester.com, which is great, except now I'm royally confused. The first time I ran a test, here's what it said (in the SPF section, where the problem is that: <strong>You are not allowed to use one of your sender email addresses</strong>)</p>
  
  <pre><code>What we retained as your current SPF record is:
    v=spf1 a mx ~all
  
  It should be changed to:
    v=spf1 a mx ip4:some-ip-address ~all
  
  Need guidance? Visit the guide for cloudflare.
  </code></pre>
  
  <p>When I clicked the link to the guide for CloudFlare, it literally said my new TXT record should be <code>v=spf1 a mx ~all</code>, which basically contradicted the previous page. So... perhaps the initial diagnostics page was specific guidance while the guide for CloudFlare was just general guidance, on where to put the record? Anyway, so I didn't have a <code>TXT</code> record with <code>v=spf1 a mx ~all</code> in CloudFlare (unusual again given the previous page said it had retained a SPF record as such), so I added it. It didn't do anything to fix my score. </p>
  
  <p>So what I thought then was, OK let's follow the diagnostic's page's specific guidance and add the IP address. The next time I ran a test, I got:</p>
  
  <pre><code>What we retained as your current SPF record is:
    v=spf1 a mx ip4:some-ip-address ~all
  
  It should be changed to:
    v=spf1 a mx ip4:some-ip-address ip4:different-ip-address ~all
  
  Need guidance? Visit the guide for cloudflare.
  </code></pre>
  
  <p>And... you guessed it, following these instructions continually just gets me to a never ending cycle of new ip addresses being added to the record, but nothing actually changing my score. Like, now I'm at:</p>
  
  <pre><code>What we retained as your current SPF record is:
    v=spf1 a mx ip4:some-ip-address ip4:different-ip-address ~all
  
  It should be changed to:
    v=spf1 a mx ip4:some-ip-address ip4:different-ip-address ip4:another-ip-address ~all
  
  Need guidance? Visit the guide for cloudflare.
  </code></pre>
  
  <p>Has anyone else had experience with this? If you can't tell, I'm a total noob to SPF and have no idea how to fix this honestly. For context, My domain and mail are managed by Gandi, but redirected through CloudFlare, so CloudFlare is where my DNS records are actually kept.</p>
