Therefore, each Postfix instance still needs a main.cf file where you configure the myhostname, inet_interfaces, and the domain(s) that the instance will receive mail for (in mydestination, virtual_mailbox_domains, etc.).
> (in the same way of an Apache server with vhosts)Apache does not forward requests for vhosts. Instead, Apache looks at the HTTP client's "Host:" header in the http request, and then it serves files from the document tree for that host. Wietse It is clear Wietse , Topic closed... Many thanks for your time. Have a nice week-end...
