I’m sorry, I meant to talk about imap-ssl-program, which I mentioned
above that quote. So it should read: “imap-ssl-program in imap.el
only tries SSLv2 and SSLv3”
But you are right, I’m using “:stream ssl” among mail-sources.
If I remove that, the connection uses STARTTLS, which ultimately
calls starttls-gnutls-program, for which I suggested
(setq starttls-extra-arguments '("--strict-tofu"))
in bug#16978 to avoid MITM with “trusted” certificates.
Changing to “:stream tls” seems to invoke tls-program, about which I
filed bug#19284.
Best wishes
Jens
