Yes, that's probably what's happening. > smtp_tls_session_cache_database This is undefined for all instances. > smtpd_tls_session_cache_database This is defined to the default for all instances: smtpd_tls_session_cache_database = btree:/var/lib/postfix/smtpd_tls_session_cache > Also, what is the configure random source, and what OS? > > tls_random_source This is fedora34: tls_random_source = dev:/dev/urandom Thanks, Alex
