Hey guys,

at first, I am new with cPanel and I am little frustrated.

We have an external mailserver, so far so good.....

MX point to the mailserver and all mails are rejected as spam we send from our Server.

Tried to configure /etc/mailips
Tried to whitlist the cPanel Server on the Mailserver
Tried to set DNS with DKIM DMARC and SPF same like our Mailserver but impossible about the hostname on cPanel

What is the right way or workaround to make it possible. Always get authfailure......

Think is not a big thing but I am forced to use cPanel about an application.

Need some help and can provide RSPAMD logs.
