well, if your clients (some old server installations) only support tls1.0,
it's better to allow it than forgint it to go plaintext or reject the mail
at all.

Much to my amazement the Postfix (that comes with CentOS 7 - v.2.10
IIRC) defaults to using no TLS at all for outgoing mail. You need to
manually enable opportunistic TLS.
I remember there were servers that announced using TLS but failed
configuring it, producing temporary error.
For cases like this, you must be prepared to disable TLS for those
servers/domains, or be prepared to lose mail.
