as far as i understood you would like to allow people to use your local
efw as an smtp for remote users.

efw is only designed to act as an smtp proxy, which means it intercepts
outgoing connections from a client to an smtp server, and backwards, a
connection from the outside to your local mailserver.

what you try to do is using the firewall directly as an smtp in order to
allow people to relay mails through it.
this does not work, because otherwise you would have an open relay which
allows spammer to send mails over it wherever they want.

you solve this by letting your remote users use their providers smtp
server, which has to allow relaying mails from its own local ip addresses.
