I know enough to get myself in trouble and prefer to avoid trial by error with my issue hence why I am seeking help.
I use my domain mainly for email, I have had it forever. of late people have been telling me that they do not receive my emails or they get flagged as spam. upon further investigation, I looked into authenticating my domain. It looks like I have old SPF and DKIM records from mandril which I no longer use anymore (maybe that is part of the issue?)
please advise ways to authenticate my domain? also, how do I properly set up DKIM and SPF, generate new appropriate records and am I even barking up the right tree?
