   Trying to get my head around spf and dmarc. Once again trying to lessen my dependence on Google, but have my whole family hanging on the same domain which complicates things a bit

     @sldrant You can forget DMARC. It's not necessary, designed around corporate needs, and breaks participation in mailing lists. SPF is really easy, just allow the hostnames/IPs you want to allow to send mail with your domain on the envelope.

     @dalias spf does look straightforward. Dmarc I'm really not sure about, and dkim might be too far (or may have to move all family smtp to my server instead of their own Gmail etc, though not sure how they have it configured really)

     @sldrant DKIM I also dislike: it provides nonrepudiation, meaning if someone leaks your emails there's cryptographic proof of authenticity. Another corporate oriented, dubious for normal ppl thing. And you can totally do without it.
