I have a machine where IPv6 connectivity is second-class (Verizon Fios does not offer IPv6, so GRE tunnel via Hurricane Electric), and where historically there was more impedance (stricter inbound policies on remote servers) for IPv6 SMTP. So I chose to deliver only via IPv4: $ postconf -Mf smtp/unix smtp unix - - n - 150 smtp -o inet_protocols=ipv4 And for a few v6 only domains I have: $ postconf -Mf ipv6/unix ipv6 unix - - n - 150 smtp -o inet_protocols=ipv6 -- Viktor. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
