Hello,

I run postfix as a mail relay. There is no local delivery on the host.
Mail is relayed to another server. I am using relayhost directive. Is
there any way I can have multiple relayhost in case one fails?

I would also like to limit relaying possibility to hosts in a list, is
that done through the mynetworks directive? It does not appear to work,
I guess I should be using something else...

Any help would be appreciated.
