ssl_min_protocol = TLSv1.3 does not work
...n, I'm getting an error that 1.3 is an "Unknown
ssl_min_protocol setting".
Reading the source code, it seems that `openssl_min_protocol_to_options` in
`src/lib-ssl-iostream/iostream-openssl-common.c` is simply missing an entry
like
{ SSL_TXT_TLSV1_3, TLS1_3_VERSION, SSL_OP_NO_SSLv3 | SSL_OP_NO_TLSv1 |
SSL_OP_NO_TLSv1_1 | SSL_OP_NO_TLSv1_2 }
Is this a bug, something intentional, or has it simply not been added yet
because nobody has been crazy enough to ask for it?
Kind regards,
Laurens

You need to set a minimal version.

[RFC master-2.2 0/1] Support OpenSSL 1.1 API for setting allowed TLS versions
Hi,
I came up with the following patch while trying to figure out a good solution
for the situation described in Debian bug #871987[1]. In short, OpenSSL in
Debian unstable has disabled TLSv1.0 and TLSv1.1 *by default*. That means that
unless an application requests otherwise, only TLSv1.2 is supported. In the
world of e-mail this is seemingly an issue, as there are still way too many old
clients
