"By default, Postfix uses IPv4 only, because most systems aren't attached to an IPv6 network." According to Google, third of their users access their service via IPv6.

So, Google agrees with the Postfix docs, correct?

Based on occasional issues raised here, it appears that some distributions package Postfix with IPv6 enabled, resulting in issues for people in the common circumstance of having IPv6 enabled in their OS and doing some sort of autoconfig without connectivity to the global IPv6 Internet. I don't believe that we've ever had someone come here with an actual problem rooted in Postfix not enabling IPv6 by default. Do you have such a problem or is your concern purely on principle?
