If it's for consistency, you would *not* have local mailers,
but you would configure everything to point at your HA postfix
relay. However I personally like local mailers as long as
something is automatically monitoring that they are well, and
you may find programs that will not work otherwise.

Not really, but it's basically going through the "basic
configuration readme" and answering

For local mailers:

        What domain name to use in outbound mail: $your_domain.com

        What domains to receive mail for: none at all

        What clients to relay mail from: localhost only

        What destinations to relay mail to: default (nothing)

        What delivery method: indirect:  relayhost = [mailout.$your_domain.com]

For your HA relays:

        What domain name to use in outbound mail: $your_domain.com

        What domains to receive mail for: none at all

        What clients to relay mail from: your local networks

        What destinations to relay mail to: nothing (not applicable)

        What delivery method: direct

Hope this helps.
