In germany you have to set up minimum 2 nameservers for your domains.
for that reason i decided to use external solution from namecheap.
i installed hestiacp successfully without dns server
when i setup email i can click on that nice button dkim support
but i know i have so setup additional entry in dns to get whole thing to work
but i am stuck at this moment
and do not know where to read out the dkim information for my dns setup
help appreciated
