Hi! Mail emitted by customs PHP script was from firstname.lastname@example.org, i change into webmin/network/network-configuration/DNS-client the Hostname from sd-22xxx to mysitename.com and now everything work nice with mails emitted from email@example.com.
So now, i have a problem with SSL certificate, i have a error because deliverer must be sd-22xxx and not mysitename.com!! Only for Website SSL, panel SSL work nice....
How to resolve this?
