Hello!I recenly have put an smal server, with debian 2.2, on internet. I want to use it as a pop3 and smt server for no-local users. If I put "host_accept_relay = *" I can send mail form any place, me and everybody, so. What is the correct and secure way to do it. I have seen some ISP's that only accept mail form yo if yu have a username (mail acount) and correct password.
Thank all you for your help
