this is a configuration i've made vor a mailserver with no local users an
a lot of virtual domains on it...
and i still try to find out the concept of exim;)
it also works if i donot make any lookups in the router section:
----------------------------------------------------------------
lookuphost:
driver = lookuphost
self = fail_soft
transport = remote_smtp
self:
driver = lookuphost
self = local
transport = mysql_delivery
----------------------------------------------------------------
as i read in the doc's this makes the following:
look if the mx of a vhost = localhost -> if yes pass it to the
directors... [ i dont know why i need a transport here ]
(btw. what happens if the virt. domain has more MX eg. from a backup
mailserver)
then in the directors section i do some database lookups concerning
aliases, vacation... if this fails it also returns an error message
(unroutable domain).
so, finally: what and where is the best way to look if a domain is local
(it schold be in a mysql database)?
1.) in the router's configuration, or
2.) within the directors...
