Hi,
I have setup DKIM as instructed in the tutorial in DigitalOcean droplet. But it is failing. This is what gets sent when I send an email:

Below is my DNS file setting in godaddy account:
<^>TXT
@
TXT value: "v=spf1 a mx ip4:104.236.55.45 ptr:secureserver.net ~all"

Host:mail._domainkey
TXT value: "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDPfYWbz5NrewMStqOI62sDvhFtrok JKxgl/tK90mWP0dXia3Stae60Do208l7LJSKWXdqApw0yTQrdXxxb7hMewDMvaSnc+rAz/9nuxDM0tQ1 UqrTYqINgSmVAHLKJoKIorqRcjXQ/AQO3AoIcEP+HBkpCP6XqUSxj7NxmvA6khwIDAQAB"

What is wrong in above setup?
