Yes, the input list (Tranco) is likely heavily skewed towards HTTPS, but not exclusively so. If you know of a more specifically targeted list of top domains by SMTP traffic, I'd be happy to take a look at that. > Things should look noticeably different circa 2028. I think if we're looking for adoption purely through updates of the underlying library and its defaults, then I'd probably estimate that we'll get to maybe 30-40% by then? Granted, that's a big step up from where we are now. IME, organizations are very much married to the L in their OS's LTS releases, so unless those bring in the newest libraries, adoption will progress more on a 10-15 year horizon. The HTTPS ecosystem moved significantly faster because it's being driven on the client side by, effectively, two companies. The long tail on the server side there will also be long, I expect. -Jan _______________________________________________ TLS mailing list -- [email protected] To unsubscribe send an email to [email protected]
