Hi,
I tested under Debian Buster (actual testing version)
with openssl. After the installation I lost the possibility to serve TLS
to TLS1.0 and TLS1.1 Clients.
Debian buster runs with openssl 1.1.1 and a new TLS security setting.
In /etc/ssl/openssl.cnf we find
CipherString = DEFAULT@SECLEVEL=2
Of course there could be just a change to SECLEVEL=1 or SECLEVEL=0,
but than the security for the whole system will change.
With adding
SSL_CTX_set_min_proto_version(sctx, 0);
in tls-openssl.c
exim was able to serve TLS1.0 & TLS1.1 again.
I am not right sure where would be the best place to add this setting.
Regards
Torsten
