Webmin and DKIM

[Linda Pagillo]

Good day everyone. Quick question and please forgive me if this is
redundant. I have a Postfix server running on CentOS7 and I use Webmin to
manage it. Is there a way for me to set up and configure DKIM using Webmin?
I have been searching Google and the only thing I could find was something
back from 2009 which says that it was not possible. Ten years later.. I'm
hoping that it is. Can someone please let me know if this is possible and
perhaps point me at the instructions? Thanks in advance.
