Zitat von c cc <sub...@gmail.com>:
Hi all, Thanks for all your help. Since we are using EC2 from Amazon and they don't support ip6 on EC2, they recommended me to force Postfix to send email using ipV4 by changing: inet_protocols = all to inet_protocols = ipv4 and restart or reload Postfix If I change to ipV4, would it create more problems for my Postfix? Once again, thanks for your help. Charles
You can't reach IPv6 only sites anymore, so no additional problem as of now. But this may change later in the century ;-)
