SPF DKIM DMARC Authentication - DNS - 07:53am Jun 17, 2020 CDT -
My MDaemon Pro 16.04 Setup Windows 2012 R2 (domains and IP's changed)
mail.PrimaryDomain.com IP: 208.56.125.25
I have a number of other domains on the same server, each domain pointing to/using the same SMTP host name and IP under Setup > Domain Manager.
domain2.com > mail.PrimaryDomain.com IP: 208.56.125.25
domain3.com > mail.PrimaryDomain.com IP: 208.56.125.25
So all mail domains are using the primary domains SMTP settings: mail.PrimaryDomain.com IP: 208.56.125.25
Is this ok?

Next under Security Settings > Sender Authentication
I would like ALL mail to go through SPF verification so SPF is enabled... |
