I agree, but I don't know how to control rules for 587?
How do I tell it to do something only on port 587?
I am not sure why you are saying that clients on port 25 must
authenticate. Port 25 should be recieving mail for local users
from anywhere in the universe? Perhaps you mean that clients
submitting outgoing email must authenticate on Port 25? Ideally,
I wouldn't have any mail submitted on 25 accept for local deliveries.
I am thinking that 25 is for incoming email and 587 should be an
outgoing mailbox, recieving mail from local and authorized users
to send out to the universe.
