Danielle

You need to put my suggestion inside the connect ACL on your system. For
example you could have something like this:


# This will probably be near the top of the config
acl_smtp_connect  = acl_check_connect
.... more "acl_xxx =" lines

....

begin acl

acl_check_connect:


warn  condition = ${if ={587}{$interface_port}}
      set acl_c_mail_submission_port = 1
      domains = !+local_domains

# You need to actually accept it as well!
accept domains = !+local_domains

# end of connect acl

... other acls ...

begin routers

## Note how the condition is put within the router definition
## remember more than one router can be run on a message,
## so I've added in a no_more
smart_route:
    driver = manualroute
    domains = !+local_domains
    transport = remote_smtp
    route_list = * ip_address_for_smart_host
    condition = {if acl_c_mail_submission_port{1}}
    no_more

other_route:
    driver = manualroute
    domains = !+local_domains
    transport = remote_smtp
    route_list = * ip_address_for_another_host
    no_more

.. other routers perhaps

begin transports

remote_smtp:
    driver = smtp

The above is untested and likely to have errors somewhere!

Test syntax first:
#exim -bV

Now test functionality:
#exim -bhc ip_address_for_a_mail_submission_port_system

....
helo name_that_the_client_system_might_use
....
mail from: user@???
....
rcpt to: user@another_example.co.uk
....
data
Type anything you like here and finish with a fullstop or period and hit
enter again
.


Choose the IP address and email addresses carefully and you will be
testing what exim would actually do to your email without trying it out
for real.  Read the output to each bit of the test carefully.

This is the reason why I bought exim in the first place 8)
