Here is a router from my configure file:
catch_all:
driver = redirect
data = admin@${lookup mysql {SELECT domain FROM domains \
WHERE type="local" and domain="${domain}" }}
regarding the part "driver = redirect"
what exactly does it do/mean?
I presume it redirects or tells the router to redirect.
where does it redirect from and to?
what tells it where to redirect to?
I am sure this is pretty basic stuff but the router syntax is just not
very intuitive to me.
