What the Exim documentation actually says is
$host: When the "smtp" transport is expanding its options for encryption using |
TLS, $host contains the name of the host to which it is connected. Likewise, |
when used in the client part of an authenticator configuration (see chapter |
35), $host contains the name of the server to which the client is connected. |
Note the qualifications ("When ..."). The return_path option is a
generic option which is expanded before the transport is called, and
therefore before it connects to any host, so $host is unset at this
time. There may, of course, be a list of hosts to which it will try to
connect. It does not re-expand return_path for each host.
Exim just isn't designed for intermittently connected environments.
