SMTP localnet accept on PVE is not IPv6 compliant #5
Description
On PVE, /etc/postfix/main.cf has the following line (network obscured):
mynetworks = 127.0.0.0/8 192.168.4.45/22 [fe80::5a47:caff:fe74:8c3c]/64
'ss -lnt' shows what I believe to be the correct line:
[::]:25
As a "guess", postfix's SMTP is listening correctly, but I am not competent to open up the IPv6 firewall correctly.
I'm going to move along at this point until I develop the competence to resolve this later.
