Hello, I'm running postfix 3.4.5 and email sending/receiving is working. I am however noticing an message:
Jul 2 14:59:44 mail postfix/smtp[14345]: Untrusted TLS connection established to gmail-smtp-in.l.google.com[173.194.68.27]:25: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (2048 bits) server-digest SHA256 I've googled and i've checked for the options smtpd_tls_CApath and smtp_tls_CApath both of which are blank. My tls configuration is using letsencrypt-generated certificates. Is there a fix for this? Thanks. Dave.
