Installing OpenDKIM

[QuakeMedia]

question - do we include the quotation mark before the v here?
v=DKIM1; k=rsa; "

I went through this tutorial and verified all the settings afterwards. There should be no quote marks at all in the record, otherwise it is marked as invalid. A good site to check your email verification and whether it will get sent to spam is http://mail-tester.com. It also includes other steps to take to ensure your email is not sent to spam.

Hope this helps
