Did u pay for subscription/support?what can we do in order to make this mail gateway : professional one ?
when the tests succeed , probably yes .Did u pay for subscription/support?

But not before.
nope, professional for me mean : not being blacklist by main smtp server (gmail, etc ...) at the first time , we install the Gateway.So what you do you mean with "professional"?
I expect you talk about professional help from our enterprise support team and a supported configuration.
Gateway , yes.SPF record configuration has nothing to do with a Mail Proxy, you need this publish a SPF in DNS. DKIM is optional via CLI, but not needed by all as most add DKIM signature on their mail server.
You mix a few things up, the Proxmox Mail Gateway is acting as a gateway/proxy. If you configure it properly, you have a great and worry free SMTP gateway.
