The reason was this line in /etc/dovecot/conf.d/10-ssl.conf:

Looks like support for SSLv2 was removed from openssl 1.1 completely
(not a bad move, it's known to be insecure since years) - but no longer
recognizing it as excluded protocol is (at least) a bit annoying ;-)

So - who should receive a bugreport? openssl for breaking backward
compability, or dovecot to adjust the default config?

Even though openssl removed the SSL_TXT_SSLV2 macro, one could also argue the
fault lies with the application. Compare this (non-dovecot) sample exhibiting
the same issue:

Note the distinct lack of a

else if (strcasecmp(ssl_name, "SSLv2") == 0) {
ec_log_debug("OpenSSL does not know about SSLv2, and I don't either");

section that would have addressed the issue one way or another.

This needs either a bugreport and/or a fix submission please.
