My report is specifically/solely about the addition/use of the

I don't see that in your configuration.
Are you using it? In a config using Dovecot's submission proxy?
Hi,
In my Centos-8 server, it was not necessary using "Options = ServerPreference" parameter.
My openssl.conf look like that :
openssl_conf = default_modules [ default_modules ] ssl_conf = ssl_module [ ssl_module ] system_default = crypto_policy [ crypto_policy ] *.include /etc/crypto-policies/back-ends/opensslcnf.config*
And /etc/crypto-policies/back-ends/opensslcnf.config : CipherString = @SECLEVEL=2:kEECDH:kRSA:kEDH:kPSK:kDHEPSK:kECDHEPSK:-aDSS:-3DES:!DES:!RC4:!RC2:!IDEA:-SEED:!eNULL:!aNULL:!MD5:-SHA384:-CAMELLIA:-ARIA:-AESCCM8 Ciphersuites = TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256:TLS_AES_128_CCM_SHA256 MinProtocol = *TLSv1.1* MaxProtocol = TLSv1.3

Hi,
In my case, it's value for MinProtocol that was wrong : must by TLSv1.1

sry, then i'm unclear re: the point you're trying to make.
this issue is ONLY about the problem re: THAT parameter's use, not re: general SSL error messages/causes.
