Okay, this has been bugging me for awhile and I've just not posted about it due to laziness however since I posted the courier issue I thought maybe I would post this one as well. I would like people to have to authenticate in order to send mail through my server. As it is now if you even try to authenticate it wont let you. Here is the contents of my main.cf What do I need to change in order to get the server to authenticate instead of just letting anyone send mail through the server?
SMTP authentication is enabled by default in any ispconfig 3 setup. Please make sure that you installed your server exactly as described in the perfect setup guide for ispconfig 3 and the linux distribution you are using.
