I sent this message to my personal domain from my Yahoo Mail account just now: Jun 16 01:46:01 shell postfix/smtpd[29319]: connect from nm4-vm6.bullet.mail.gq1.yahoo.com[98.136.218.165] Jun 16 01:46:01 shell postfix/smtpd[29319]: Anonymous TLS connection established from nm4-vm6.bullet.mail.gq1.yahoo.com[98.136.218.165]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) However, it appears that Yahoo's MX did not accept TLS for my outbound reply. That's concerning....
