I can not use any of the submission ports. Not supported by Telefonica. It is port 25 we use.
The more I hear about them, the more I think they're incompetent. Other ISPs have blocked port 25 due to security issues. Not supporting TLS is unbelievable However, if you absolutely must use port 25, then use the hosts file or local DNS to point to their IPv4 address.
TLS is not related to this. It is supported. See my log:
<2.6> 2019-08-19 16:29:46 Telcontar postfix 5421 - - 97C39320B46: removed <2.6> 2019-08-19 16:29:47 Telcontar postfix 5158 - - Anonymous TLS connection established to smtp.telefonica.net[86.109.99.70]:25: TLSv1.2 with cipher ADH-AES256-GCM-SHA384 (256/256 bits)
If HE does not allow me to use port 25 to connect to my ISP, I will not connect my main computer to IPv6.
Carlos, it's an experiment, for fun, but you keep putting up stumbling blocks for yourself. What does it matter if you can't use it send emails over?
It breaks mail in the sole machine which has the tunnel, which is the one that mails to me on my phone to tell me that my home IP has changed. If the machine happens to see IPv6 and prefers it, then mail breaks. On the other hand, mail was one of the things I wanted IPv6 for. For testing how it goes with it. Well, it doesn't, at all.
Btw, your ISP does not seem to use IPv6 -
# host smtp.telefonica.net smtp.telefonica.net has address 86.109.99.70
Oh, that's fortunate. Really, not kidding. :-) One problem solved. - -- Cheers, Carlos E. R.
