Yes, all of that is possible with Exim. You would need to set up a manualroute router as described here: http://www.exim.org/exim-html-current/doc/html/spec_html/ch20.html You would add a condition to the router to detect if the domains were different, with something like: condition = ${if !eq{$domain}{$sender_address_domain}} You could store a list of domains which you want to filter, in a file and then add an option like this to the router: domains = lsearch;/path/to/file Alternatively you could do some other type of lookup, as per: http://www.exim.org/exim-html-current/doc/html/spec_html/ch09.html Finally, you'd need to make sure that mail that comes from the filtering host, doesn't get routed back to it, causing a loop. I'm not sure this is the best way of doing it, but I'd update the first condition that I mentioned earlier in the email as follows: condition = ${if and{{\ !eq{$domain}{$sender_address_domain}\ }{\ !eq{$sender_host_address}{ip.address.of.filtering.host}\ }}} I really wish you could add multiple "condition" options to a router so you didn't have to create messy configuration like that. -- Mike Cardwell (https://secure.grepular.com/) (http://perlcv.com/) -- ## 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/
