According to the docs [1, 2], "smtp_tls_note_starttls_offer=yes" should log when a server offers STARTTLS. However, I've been testing among my own SMTP servers, and while I can verify that TLS is being used (with "smtpd_tls_loglevel=1" on the smtpd side), I can't tell what TLS capabilities the smtp (client) is seeing. I'm using Postfix 2.7.0.
How do I make smtp_tls_note_starttls_offer work? Thanks in advance. [1] http://www.postfix.org/TLS_LEGACY_README.html [2] http://www.postfix.org/postconf.5.html -- Yang Zhang http://yz.mit.edu/
