Not sure I agree - it only takes one extra ACL test to listen on both and
reject on 587 if not authenticated - something like this which was posted by
Bruce Richardson on 11th April:
accept hosts = +auth_relay_hosts
condition = ${if eq {$interface_port}{587} {yes}{no}}
endpass
message = relay not permitted, authentication required
authenticated = *
(Hint: Marc - a simple Google query for 'exim port 587' found this...)
I always take the view that it's easier to change-control a single config
file than several, especially when you can easily encapsulate the
port-specific processing like this. But running 2 instances remains a valid
option.
