Your GW is mark spam, not hide internal host

when the tests succeed , probably yes .
But not before.

So what you do you mean with "professional"?

I expect you talk about professional help from our enterprise support team and a supported configuration.

nope, professional for me mean : not being blacklist by main smtp server (gmail, etc ...) at the first time , we install the Gateway.

SPF is not operationnal at the begining (i mean the doc can explain that DNS record must be setup ... just that)
DKIM is not implemented ... i found tutorial on the web.

Without this two thing the gateway is blacklisted in few day, ... few hours : first mail send , in the junk or spam of gmail !

This is not the case for me.
 
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.
