If it is any help, there's really no concrete reason for mail systems to 
disable TLS v1.1 or v1.2 if they limit the ciphers to strong ones and 
are using a modern implementation (e.g. OpenSSL 3.x, LibreSSL 4, etc.) 
of TLS. Disabling everything except 1.3 is nice on a security checklist 
because it won't soon be obsolete and it's simple, but it is not 
justifiable by any tangible risks.
