Sorry. What I meant is: I did remove 'inet_protocols=ipv4', thus no
inet_protocols setting in my main.cf

Ok, understood.

Current setting:
mail> grep inet_protocols main.cf
inet_protocols = all
mail> postconf inet_protocols
inet_protocols = all
Now, I removed this line from main.cf, thus no more settings regarding
inet_protocols:
mail> grep inet_protocols main.cf
mail> postconf inet_protocols
inet_protocols = all
Now, I do reinstall postfix:
mail> pkg install -f -y postfix
(FreeBSD's package compiled by poudriere)
After reinstallation:
mail> grep inet_protocols main.cf
inet_protocols = ipv4
mail> postconf inet_protocols
inet_protocols = ipv4
That is what I meant, the line 'inet_protocols = ipv4' had been added.

Yes I do understand that.
Ok, I will keep 'inet_protocols = all' until IPv6 will be enabled by default.
Thanks for your explanations.
