If mynetworks is undefined then it takes its value according to
mynetworks_style and the default for this setting changed for Postfix 3.0 -

However external authenticated senders are not local (and I don't trust any
non-authenticated senders outside the host) so in such a case the message
from amavis is correct ('Nonlocal recips but not originating') while the
warning ('Open relay?') is unnecessary.
