Hello! I'm on the way to migrate some web-projects from a managed vServer to "my own" vServer using virtualmin on debian 9. Currently I have disabled BIND becaus I want to use the nameservers of my hoster in order to save resources on my vServer and to spare out other challanges like redundancy and so on. Till now I was happy with this setup but now I have realized, that DKIM only works with enabled DNS feature out of the "virtualmin-box" (as described here: https://www.virtualmin.com/documentation/email/dkim).
So... would it be a good practice to enable BIND on my locale machine although I don't use it just to get DKIM working? Or is there an other way to get DKIM signed mails without enabled BIND feature? It also may be, that there are other advantages running a locale DNS server I don't see with my rookie-eyes...?
I would be very pleased to get some practical hints from you professionals.
kind regards, Thomas
