How to disable open relay on Postfix?
Hi everyone,
Open relay, yet again, concerns me. I followed the Falko's guide on installing Debian postfix with some other stuff, things've been running cool, except for the open relay problem. As I configure MS Outlook to test email, even with no password, the test emails can still be sent. A open relay problem, isn't it?
I've tried several ways to disable it, but none worked. Can anybody help me out?
Thx alot ^^
