Hi, does anyone know how to restrict smtp internet access. All our email is sent via an ISP's email server. I want to stop spam coming in that doesn't go via the ISP's server so if I can only allow my ISP's server to send me email on SMTP then it may help.
I have read how to do it on SME 5 but the files it references aren't there in SME 6.
