System mails not working

Hi!

I am trying to configure hestiacp. The correspondence works, but the control panel notifications (email account creation, user account creation) are not sent by the system. What else and where do I need to set it up for it to work? I opened these ports: 8083, 80, 443, 143, 993, 110, 995, 25, 465, 587

Thanks!

check exim mainlog, should provide some informations what fails.

Oracle cloud blocks outgroing mail traffic…

Ohhh… I didn’t know that…
It is strange, because I also enabled the ports required for sending mail in the Oracle control panel, and by typing the netstat -plntu command, it can be seen on the console that it is listening on that port.

its not about listening, its about sending.

I mean listening → opened and can send/receive packets.

OK, I moved from Oracle cloud to Linode.
Installed, but SPF and DKIM records missing from control panel hostname, wich is a subdomain (hcp.mydomain.xy)

Where can I see the spf and DKIM settings for the domain of the control panel on the control panel?
Control panel: hcp.mydomain.xy

have you got any idea?
