Question

Hello, on "DigitalOcean - DNS - View domain.tld - Add record - TXT (Enter name, Enter record) - Create" https://cloud.digitalocean.com/domains I want to add DKIM for domain on Debian (ISPConfig, Webmin), where I can find DKIM record on server? Thank you.

You need to generate the DKIM key yourself. On the server, first install the nessasary packages:

sudo apt-get install opendkim opendkim-tools

Now we can generate the key using:

sudo opendkim-genkey -s mail -d your-domain.com

This will create two files, mail.private and mail.txt 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:

cat mail.txt

You should now see something like:

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

The part in between the parentheses is what you'll want to paste into the DNS panel. For a full tutorial on how to integrate the DKIM key with postfix on Debian, check out: https://www.digitalocean.com/community/questions/dkim-on-dns-panel-digitalocean

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

1st part you could give the name you want, for me it's DKIM
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

I used that to validate : http://dkimcore.org/c/keycheck
