At the end I think the mail is received in plain text
Could be the problem at my side?
your problem is that you miss ssl3 support with yahoo still use :(
smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3
smtpd_tls_protocols = !SSLv2,!SSLv3
this makes it worse or have no effect if you dont have a ssl library
that support it anymore, yahoo should upgrade to a working tls to solve
it
you can disable starttls for there client ips, if thats solve it, write
to yahoo about it
