If that would work, great, no awesome! But I just tried that quickly, and unfortunately it only binds to one address, the IPv4 address in my case. http://www.postfix.org/master.5.html does not state what happens if there are multiple addresses behind the given host. Duplicating or multiplying the number listeners just for the sake of having IPv4 and IPv6 available is really not ideal when tuning the process limits :-( Thanks ! Christian
