We were having a discussion on the possibility to disable TLS 1.0 and 1.1 for
MTA to MTA communication, and based on the numbers we've seen so far, it
doesn't look that far fetched.
What's the common consensus in the mail community about this currently?
I don't really see the point, unless

TLS in SMTP mail is also not sad; it's fundamen

Mailspike is the worst RBL that we test (out of 33).
They have the lowest catch rate (last month: 41.9%) and a high false
