If you want all outgoing mail to go to a central relay site, define
SMART_HOST as well. Briefly:
LOCAL_RELAY applies to unqualified names (e.g., "eric").
MAIL_HUB applies to names qualified with the name of the
local host (e.g., "eric@mastodon.CS.Berkeley.EDU").
SMART_HOST applies to names qualified with other hosts or
bracketed addresses (e.g., "eric@mastodon.CS.Berkeley.EDU"
or "eric@[127.0.0.1]").
