Hello,
I use tunnel broker in my server and when I was trying to sent email to google I receive this error message:
Jan 31 09:33:22 www postfix/smtp[31438]: connect to ASPMX.L.GOOGLE.COM[2a00:1450:400c:c08::1b]:25: Connection refused
My IPv6 is fine and working, also on postfix.
$ curl --verbose --verbose https://mail.yahoo.com
* Trying 2a00:1288:f03d:1fa::4000:443...
* Connected to mail.yahoo.com (2a00:1288:f03d:1fa::4000) port 443 (#0)
* ALPN, offering h2
any one have idea how to report the problem to HE to fix it ?
You can email HE at ipv6@he.net
