# The keys are the group names associated with a Postfix role, and the
# values are the name and group (optional) of the instance dedicated

# For internal services, we also specify its (non-routable) IP address
# and port.
# XXX it's unfortunate that we can only specify a single address, and
# therefore have to limit the number of outgoing SMTP proxy and
# IMAP server to one. Since hosts(5) files cannot map and IP
# address to multiple hostnames, a workaround would be to use
# round-robin DNS, but we can't rely on DNS as long as our zone is
# unsigned.
