Yeah, When i recompile postfix from the source, I receive an "unsupported protocol: cyrus" in my mail log. And when I compile Postfix through a Postfix-MySQL RPM I've found I receive the "Login Failed" Error.
Also, i tried the "yum install --enablerepo=centosplus postfix" line mentioned in the tutorial again (as it worked for me when I first setup my mail server). But it doesn't include mysql support any longer. Any ideas why that is?
