DKIM on DNS panel DigitalOcean

You need to generate the DKIM key yourself. On the server, first install the nessasary packages: <pre> sudo apt-get install opendkim opendkim-tools </pre> Now we can generate the key using: <pre> sudo opendkim-genkey -s mail -d your-domain.com </pre> This will create two files, <code>mail.private</code> and <code>mail.txt</code> The first one is the key itself, and the second one shows the DNS TXT record that you’ll use. Let’s take a look at that by running: <pre> cat mail.txt </pre> You should now see something like: <pre> mail._domainkey IN TXT ( "v=DKIM1; k=rsa; " “p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDblMQxNcTE0LKzE8ypsmLVJGzWT0eR08+PcGKbK/lHo5el4n6pFgQarN/ppSSVM3Hvn64mPLBqq1JWkDYf1IhfC0ZTF6rN1kgCjBg2mb854dDCcM/wUcf593GVGtxiF+nPxXl7aecA+uyQVcdy+bxvyAHaVTx+zMxbxr48miJGGwIDAQAB” ) ; ----- DKIM key mail for your-domain.com </pre> The part in between the parentheses is what you’ll want to paste into the DNS panel.

I just found this tuto : https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy

into the DO Panel, under DNS, I add a TXT Record

1. 1st part you could give the name you want, for me it’s DKIM
2. 2nd part : you cut and past the string between ( ) or between " "; for me I cut the part between “” and i’d include them ; mail._domainkey IN TXT “v=DKIM1; k=rsa; p=AIAfAA3FSAqASIb3AQABAAUAA4GAADAAiAKAgAAkY3vvTZ0o3fcRXh8t+dtmaFnuq0sxVP6o+YN3wNin3TYq78X2mfBRH35Yt/40jTuDAnfAsAXPUxA/rAAEvO8WTBi/WIokPZNNAEYvDWTqvAVhvAnvT4ue0xa60YyYd7hI1FZ0So6x/tklQaYqndj+AmxnAfR3bZ9RzQNf73gXybwIDAQAB” ; ----- DKIM key mail for blipblip.net
