title: How to add TXT dns record for configure Opendkim
body: <p>I need to send e-mails from my virtual server, the problem is that the e-mail containing links comes to be considered as junk! But I need to insert links in my e-mails.<br>
  So I have installed Postfix, configured it for send e-mails using my SMTP mailbox, then I am trying to configure OpenDkim for signing my e-mails.  I have done all the steps correctly except one: adding TXT DNS record!
  I have read this guide: <a href="https://syslog.tv/2010/01/11/dkim-on-debian-with-postfix/" rel="nofollow">https://syslog.tv/2010/01/11/dkim-on-debian-with-postfix/</a>.<br>
  We have to add these 2 txt dns records:</p>
  
  <pre><code>_domainkey.DOMAIN.TLD. IN TXT "t=y; o=-;"
  SELECTOR._domainkey.DOMAIN.TLD. IN TXT "k=rsa; t=y; p=YOUR_PUBLIC_KEY_HERE"
  </code></pre>
  
  <p>But I don't understand HOW I can add this records... in my DNS control panel I must specify for each new DNS record at least 3 fields: the type is for sure TXT, ok, but what are the name of the record, and the value of the record?
  I have tried to add the first as follow:</p>
  
  <pre><code>Name: _domainkey.mydomain.example.
  Type: TXT
  Value: t=y; o=-;
  </code></pre>
  
  <p>But I receive an error message that tells me that it is not possible to add a subdomain? Then I have tried to reverse the fields/value:</p>
  
  <pre><code>Name: t=y; o=-;
  Type: TXT
  Value: _domainkey.mydomain.example.
  </code></pre>
  
  <p>But this time I will not see any type of message/error from my control panel, so I don't understand if there is a problem in it or something else?</p>
  
  <p>Can someone help me please?</p>
