title: Mail SPF configuration?
body: <p><strong>THE SITUATION:</strong>
  I have ONE e-mail account per domain.
  I use e-mails such as [some-alias]@[one-of-my-domains-name]. (server: mail.[mydomain]:[secure port]
  My registrar (OVH) is different from my web host (Arvixe).
  My hosting plan is a mutualised .NET hosting.
  When I want to reply with one of my aliases, I use Mozilla Thunderbird 'Identities'. (Login = concrete domain mail account, FROM: 'the alias e-mail'.)
  (And yes, this is very efficient to avoid getting spams and unwanted mailing lists.)</p>
  
  <p><strong>THE PROBLEM</strong>:
  For some recipient using some spam protection services, I constantly get the error:</p>
  
  <blockquote>
    <p>Remote server replied: 550 Blocked by SPF ()</p>
  </blockquote>
  
  <p><strong>HINTS/QUESTIONS AND IDEAS IN SEARCH FOR A SOLUTION</strong></p>
  
  <ul>
  <li>a friend said I have to configure the TXT spf record of my domain.</li>
  <li>using different webmaster tools sites to get DIG info, I never get infos about the 'TXT' record. So I'm not sure: Should I edit this record on the side of my domain registrar or in the side of the hosting ?</li>
  <li>Current on my registrar's side the record reads:
  <code>v=spf1 a:mail.[mydomain] include:mx.ovh.com ~all</code>
  and on my hosting's side it reads:
  <code>v=spf1 a:mail.[mydomain]  ~all</code></li>
  </ul>
  
  <p><strong>THE BIG QUESTION:</strong>
  How can I solve this ?</p>
  
  <p>Thank you for your help</p>
