My SMTP server is acting as an Open Relay is as much as anyone can use it as an smtp server without presenting a valid email address or using SMTP authentication.
I see in the help pages that SMTP authentication is meant to be used but I can't see where to switch it on and I am able to send messages through it with it switched off and with a false email address.
Can someone advise urgently as there is enough spam in the world without me adding to it
Thanks
Steve
