is there a way to allow a user to send mail through our server without
putting his ip on sender_net_accept_relay?
we have many users from a lot of networks and it's not a good solution to
put every network on this exception list. I think smtp auth would be the
best solution, so the users can authenticate theirselves by giving their
username and password. I read the exim documentation but I didn't find
anything. Is there a way to do that? or is there a better solution to
filter, who we are relaying for and who we are not?
it's important that our users with mozilla and outlook also can use the
service.
