Hello Sorry if this seems a bit off topic ...
Postfix is really a great piece of software and we all thanks to Wiese for his tremendous work. But to fight spam and all other malicious problems it's getting more and more sophisticated and complex to configure every day. It is not a criticism it is a fact that jump to every sysadmin's face. Email communication require a more and more complicated machinery every day too. Does anyone has knowing of the future of SMTP ? Is there some project to replace it by some more secure protocol ? Understand me well , writing this I do not want to start some war I would like to know if there is some long term reflexion "somewhere" to build some other protocol. I know this would be a huge project ... Thanks for your attention
