From the docs: ---------- primary_hostname Use: main Type: string Default: see below This specifies the name of the current host. It is used in the default EHLO or HELO command for outgoing SMTP messages (changeable via the helo_data option in the smtp transport), and as the default for qualify_domain. The value is also used by default in some SMTP response messages from an Exim server. This can be changed dynamically by setting smtp_active_hostname. If primary_hostname is not set, Exim calls uname() to find the host name. If this fails, Exim panics and dies. If the name returned by uname() contains only one component, Exim passes it to gethostbyname() (or getipnodebyname() when available) in order to obtain the fully qualified version. The variable $primary_hostname contains the host name, whether set explicitly by this option, or defaulted. ---------- So, if you leave this unset and then refer to $primary_hostname in sections of your configuration it will pull in from a call uname() and do exactly what you specify.
