<p>Hi Tim,</p>
<p>Been through this recently. I have a couple of cloud VMs that need to send email from my domain. Adding openDKIM fixed that. There's a few resources on the net describing the procedure, searching for "install opendkim on ubuntu" or whichever linux distro you have will get you there. There's sites to test the headers, spaminess, etc, in the instructions.</p>
<p>DKIM adds an email header signed with a private key, the public key goes in a DNS record so the receiver can validate the header.</p>
<p>regards,</p>
<p>Glenn</p>
