$sender_host_address

    When a message is received from a remote host, this variable
    contains that host's IP address. For locally submitted
    messages, it is empty.


Does "remote host" imply not localhost?

Locally submitted means -bs or -bS, right? $sender_host_address
is set for TCP connections from 127.0.0.1, so that description above
doesn't seem clear (would localhost be considered a "remote host"?).


In a verify_only router is it possible to detect connection from
non-local machines? Test that $sender_host_address is defined and
doesn't equal 127.0.0.1 or the IP address(es) of the localhost?
