I have a new Digital Ocean Ubuntu 14.04 64bit box setup and am failing IPV6 tests with:
https://ssl-tools.net/mailservers/box.counterrisks.com
Any reason why IPV6 is failing?
It looks like the SMTP server (postfix on port 25) isn’t accessible over IPv6.
e.g.
telnet -6 2a03:b0c0:3:d0::c9:b001 25
fails.
It might be a local firewall issue on your end. I haven’t done much testing with IPv6 so it could be a bug in Mail-in-a-Box, although my box works fine.
