Ispconfig default postfix configuration
I am wondering why the default configuration for postfix is so ...poor. People are persistently asking the same after a perfect server install ...why is my server sending/getting spam?
Well, I understand that ispconfig must be flexible because each mail server can be set in several ways but must be more secure.
I'm not talking about spf, greylisting, dkim, rbls , fake mx, policies... just something more simple:
helo checks, helo restrictions, hostname restrictions,strict rfc.
With this settings the default config file remains flexible but really more secure.
Please do not misunderstand this post, I just trying always to help
