HI

finally i made a ticket to DO, they said they will consider to open port 25 after 60 days i create new droplet, cuz they worry about spam problem… so i agree with them. From now i just wait for a couple weeks ahead.

Hello,

I found solution somewhere if it helps you

Go to:/etc/postfix/main.cf

make these changes there:

# Enable IPv4, and IPv6 if supported
#inet_protocols = all

inet_protocols = ipv4

If it worked, just know that your vps/server doesn’t support ipv6.
