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:
https://github.com/Kopano-dev/kopano-core/blob/master/common/ECChannel.cpp#L...
Note the distinct lack of a
#else else if (strcasecmp(ssl_name, "SSLv2") == 0) { ec_log_debug("OpenSSL does not know about SSLv2, and I don't either"); continue; } #endif
section that would have addressed the issue one way or another.
This needs either a bugreport and/or a fix submission please. Cioa, Marcus -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
