CyberPanel E-Mail for multidomain
how can I change the default mail hostname in cyberpanel ?
I have four domains where i would like to set up email for.
One static ip address with a ptr record.
When i set up mail for domain a cyberpanel automatically creates a mail.a.com subdomain.
the same for domain b and c.
Where can i change the default domain for the mail server ? When the server will talk to another mail server there will be a HELO domain issue when using this different domains ?
