Hello, even when i choose in ISPmanager->Sites->options "external mailserver" ispconfig "2.2.11" makes record into /etc/postfix/local-host-names and /etc/postfix/vitualusertable which means that php or apache mailing functions and also any mailuser from local server cannot send email to specified domain, because postfix is trying deliver emails for domain locally, when mailserver is located outside Can it be solved any way ??
No, ISPConfig is definately not writing the domain of this website to the virtusertable. But it writes the co-domains to the virtusertable if you did not set them to external mailserver too. Solution: You must set all co-domains to external mailserver too.
