I have a server with multiple interfaces, more than one of which is used for outbound SMTP according to various conditions.
Is there any way to log which local interface was used for the outbound connection, on the "=>" log line? I've been looking in section 49.15 of the 4.66 spec for a suitable log selector but I can't find one. There is "incoming_interface" and "incoming_port" but, it seems, only the corresponding "outgoing_port" and not the expected "outgoing_interface". I appreciate that where an outbound interface is not explicitly specified (e.g. the default configuration), Exim might not be able to actively discover the outgoing interface from the OS. However where it has been specified explicitly using the "interface" option in a transport, it seems to make sense to be able to log that (ideally using the "I=" notation to be consistent with incoming connections).
