My exim server listens on localhost and the external interface, and on ports 25 & 587.
There are therefore 4 combinations available for connections. It strikes me that testing for these in an ACL would be useful; for example the only time I want to accept email "From:" an external address is when it arrives on the public IP, port 25. In pseudo-code, I want to "ACCEPT if Src=remote, Dst=public:25, Auth=no, From=non-local domain, To=local domain" (followed by "REJECT From=non-local domain") in order to represent "normal incoming email" and avoid relaying. However, I can't see the ACL conditions that would allow me to test for the destination IP/port ... how can I do this? -jim -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
