Setting up TLS 1.2 on Zimbra desktop 7.3.1.13063 Win10

Using Zimbra desktop 7.3.1.13063 running on Win10; how is setting up TLS 1.2 only performed?
All the guides seem to make reference to the ZCS rather than the desktop version.

I'm looking for TLS on Zimbra Desktop as well.

For more info on SASLauthd, please see the following:
ZCS saslauthd.conf.in sample
Create a text file mapping which name/password should be used for each given outbound destination:

echo mailrelay.example.com username:password > /opt/zimbra/conf/relay_password
Create a postfix lookup table:

postmap /opt/zimbra/conf/relay_password
To test that the lookup table is correct, the following should return username:password:

postmap -q mailrelay.example.com /opt/zimbra/conf/relay_password
Configure postfix to use the new password map:

postconf -e smtp_sasl_password_maps=hash:/opt/zimbra/conf/relay_password
On 8.0:
zmlocalconfig -e postfix_smtp_sasl_password_maps=hash:/opt/zimbra/conf/relay_password
On 8.5 and later:
zmprov ms <server> zimbraMtaSmtpSaslPasswordMaps lmdb:/opt/zimbra/conf/relay_password
Configure postfix to use SSL authentication:

postconf -e smtp_sasl_auth_enable=yes
On 8.0:
zmlocalconfig -e postfix_smtp_sasl_auth_enable=yes
On 8.5 and later:
zmprov ms <server> zimbraMtaSmtpSaslAuthEnable yes
